Air travel can be made safer with artificial intelligence guarding against human error. That’s the vision of Andrew Dassonville, an engineering senior at Oregon State University, who recently took second place in a national airport design competition.

Human error is the leading cause of commercial airline crashes and general aviation accidents, according to the Federal Aviation Administration. Dassonville, who studies computer science and robotics, zeroed in on radio communications as one source of human error where AI can provide a critical safety check.

Dassonville was awarded second place in the runway safety category at the 2022 ACRP University Design Competition, which challenges students to create innovative solutions for issues facing airports and the National Airspace System. The competition is sponsored by the Airport Cooperative Research Program, part of the National Academies of Sciences, Engineering, and Medicine’s Transportation Research Board.

In Dassonville’s design, an artificial intelligence-based system constantly “listens in” on radio exchanges between pilots and air traffic controllers, looking for discrepancies in communication, such as readback errors. Suppose, for example, a controller instructs aircraft ABC to climb and maintain 8,000 feet, but the pilot reads back 9,000 feet. The eavesdropping AI would catch the error and avert potential disaster.

“This system is capable of identifying that discrepancy and would alert the controller that the aircraft might not be doing what they’re expecting,” Dassonville said.

Dassonville, an avid pilot who discovered his passion for flying though the Oregon State Flying Club, saw the competition as a perfect overlap of his interests in aviation and computer science.

“As a pilot, safety is always on your mind, and you’re taking on some risk whenever you take off,” Dassonville said. “Being able to use my skills that I’ve learned at Oregon State through computer science in order to help mitigate risks in aviation is pretty cool.”

Kiri Wagstaff, associate research professor of computer science at Oregon State, advised Dassonville on the project.

“Andrew is an outstanding student and pilot,” Wagstaff said. “As a pilot myself, I’m very excited about Andrew’s concept, and I have thoroughly enjoyed discussing AI, flying adventures, and flight training with him.”

After graduating, Dassonville plans on a career that involves aviation.

“I’d love a career that combines computer science, robotics, and aviation,” he said. “It could be something that involves self-flying planes, autopilot technologies, or aviation instruments.”

Some of the reasons Andrew Dassonville loves being a pilot.

Gabor Temes, professor of electrical and computer engineering at Oregon State University, received the IEEE International Circuits and Systems Society’s Lifetime Achievement Award for his “contributions to delta-sigma converters, analog filters and signal processing, and engineering education.”

His work has improved technologies like cellphones and medical devices, and his mentorship of more than 100 students has multiplied the impact of his work.

Among his many awards, Temes received the nation’s highest professional distinction for engineers in 2015, when he was elected to the National Academy of Engineering. He was also named a fellow of the National Academy of Inventors in 2020.

Temes earned his undergraduate degrees at the Technical University and Eotvos University in Budapest, Hungary, from 1948 to 1956, and his Ph.D. in electrical engineering from the University of Ottawa, Canada, in 1961.

Prior to arriving at Oregon State in 1990, he held academic positions at the Technical University of Budapest, Stanford University, and UCLA. He also worked in industry at Northern Electric R&D Laboratories (now Bell-Northern Research) and Ampex Corp.

“Any achievements of mine are largely thanks to the excellence of my students and the support I received from my school and industry over many years,” Temes said upon receiving the award at the IEEE International Symposium on Circuits and Systems.

For the 15th year in a row, Pacific Power has awarded a grant to Oregon State University for engineering scholarships. To date, more than 100 students have received Pacific Power scholarships, which help future engineers obtain their degrees, especially in electrical and computer engineering.

“We believe in the power of education to create a lifetime of opportunity,” said Stefan Bird, president and CEO of Pacific Power, in an article about the company’s latest round of grants.

Eduardo Cotilla-Sanchez, associate professor of electrical and computer engineering and associate head for graduate programs in the School of Electrical Engineering and Computer Science, has seen how the scholarships provide benefits for his students.

He regularly takes his classes on field trips to learn about the power system equipment at Pacific Power facilities, where employees, including some Oregon State alumni, show students how the equipment operates.

“Our courses in power and energy systems provide a strong foundation to tackle problems that electrical and computer engineering graduates will encounter in the utilities industry,” Cotilla-Sanchez said. “Partners like Pacific Power are instrumental in translating the application of, for example, power system protection concepts, by facilitating co-curricular activities.”

Jeffrey Chu, a postbaccalaureate computer science student at Oregon State University, had a perfectly fine career as an attorney. After earning a law degree in 2016 from the University of Texas at Austin, Chu worked first as a felony prosecutor, then as a civil litigator.

He liked his job but came to realize that it wasn’t his passion.

Outside the courtroom, Chu’s time was occupied not only with preparing his cases, but also with a ton of monotonous data entry tasks.

“The worst was tracking billing hours,” he said. “I had to keep track of what I was doing every six minutes.”

Chu, who lives in Houston, was working every weekend and didn’t get many days off. In order to make better use of his time, he decided to teach himself to automate some of the mundane tasks. That’s when he fell in love with programming.

Around the same time, one of Chu’s friends completed a six-month coding boot camp and told him about job offers he had received, which motivated Chu even more to make a career switch. Though he could have chosen to attend a boot camp, Chu researched his options and decided he needed a computer science degree.

“I thought the best opportunity for me was to pursue a CS degree, to get a strong foundation and give myself more time to absorb the concepts,” he said.

The degree and the foundation, Chu believed, would help him develop a career as a software engineer, not just a coder. He also realized that a computer science program would give him the opportunity to pursue internships, which would in turn give him an advantage in obtaining a full-time job.

Making an informed decision

Chu dove in to researching online computer science programs.

“One thing you learn in law school is the ability to look for things and do it efficiently,” he said. “So I was pretty confident in my ability to make an informed decision after I did all my research.”

Chu liked Oregon State’s program because he wouldn’t have to take, or retake, core curriculum classes. He could dive in to computer science classes right away. He also perused LinkedIn and found that Oregon State alumni had jobs everywhere: big tech companies, small companies, and startups.

What really convinced him to choose Oregon State was the online community he found in the student-led Slack channel, where anyone can ask questions and many will share their perspectives. Students and alumni constantly interact over a wide range of topics — including classes, interviews, career choices, and professional development opportunities.

“There were great reviews about the program there,” Chu said. “And people were so helpful, building each other up and giving advice. Other programs I looked at didn’t have that sense of community.”

A funny thing happened on the way to a degree

Though Chu quit his job as an attorney to become a full-time student in 2020, he landed a full-time cybersecurity job in 2021, while still pursuing his computer science degree. Chu thought cybersecurity would be an interesting path, and a friend connected him with another friend who worked in the field, who ultimately offered him a job.

Chu has since decided that cybersecurity isn’t the field for him. He anticipates graduating in December 2022, two years after beginning the program. In the meantime, he recently finished an internship at Amazon in Washington, D.C., and is currently on a second internship at Ford in Dearborn, Michigan.

“I’m the type of person who just likes to try multiple things and see what sticks,” he said.

Jeffrey Chu’s interview tips for career-changers

Even before he started the online postbaccalaureate program in computer science, Jeffrey Chu was a fan of the student-led Slack community. During his time at Oregon State University, Chu has been an active participant in the channel, including the following, his contribution to a recent discussion about getting through a technical interview.

To give you some perspective and to contrast with some stories here, my very first tech interview went well and I got an offer for an internship after. My first year at OSU I had major imposter syndrome and didn’t apply to any internships so I was pretty stressed going into this year’s internship recruiting season as it will be my final one (hopefully). I think I owe my success to mostly luck, but there are some things I did to reduce uncertainties.

Get familiar with the interview process.
- Essentially, know how the interview will go. (Will it be purely behavioral? Two tech questions, one behavioral? Only tech questions?)
- There are a lot of anecdotes from people who have interviewed with some companies in the past if you do some research online.
Reach out to people you may know who work for the company.
- Being older, leverage the professional network you have already built.
- Even if that person doesn’t work in a tech role, they can probably put you in touch with someone who does to get some insight into how the interview may go or what it’s like working there.
Do Pramp/mock behavioral AND technical interviews.
- Practice doing LC-style questions while speaking out loud while someone watches over you and judges you. When I did my first mock tech interview I floundered on an easy merge intervals question just because I wasn’t used to the pressure.
- Behavioral wise, practicing the STAR method out loud is much more difficult than in your head.
It’s not always about getting the right/optimal answer on tech questions.
- Interviewers want to see your thought process, how you bounce back from setbacks, and how you take direction.
- Sometimes you have to get the right answer though.

Students in the School of Electrical Engineering and Computer Science, along with their family and friends, commemorated their graduation during the school’s graduation celebration on June 10, 2022.

“Our last in-person celebration was in 2019, so it was great to see how happy everyone was to watch the students walk across the stage and be recognized for their achievements,” said Gaulke Professor and School Head Tom Weller.

Oregon State University alumna Nadia Payet, who earned a Ph.D. in computer science in 2011 and is the Senior Engineering Manager for Navigation on Google Maps, shared words of wisdom for the graduates.

After losing her younger sister to cancer in 2017, Payet changed her outlook on life and offered three lessons:

Figure out what you want. It’s not what your parents or society wants for you. After her sister died, Payet shifted her focus from solely building a career to building more meaningful relationships. “I still love the successful career,” she said. “Because I listen more carefully now, I’m just a more human leader; someone who truly cares and puts her people first.”

Don’t put off until tomorrow what you can do today. She urged the graduates to pretend they don’t have all the time in the world to get things done. “I remind myself that we don’t have forever, so let’s make today count,” Payet said.

Lead with empathy and kindness. “Leadership is taking care of yourself, and empowering others to do the same,” she said, and advised the audience to practice gratitude as a path toward leading with empathy and kindness.

The graduation celebration also recognized faculty, staff, and students with awards.

Dmytro Shabanov and Harry Herzberg — Oregon State University students Dmytro Shabanov (left) and Harry Herzberg are working on a startup company to help students get better grades.

Two Oregon State University students are winning entrepreneurship awards as part of the team developing Alerty, a mobile app to help students — especially those with ADHD — perform better in class.

Most recently, the team won the Social Entrepreneurship Award at the TiE University Global Pitch Competition and was one of 30 teams to advance to the semifinal round, out of some 1,400 accepted into the competition.

Harry Herzberg, a senior in computer science, and Dmytro Shabanov, a senior in finance and marketing, are joined on the Alerty team by their business partners Jade Zavsklavsky, Artemis Kearny, Nicholas Craycraft, Alexander Victoria Trujillo, and Freya Crowe.

The Alerty app transcribes class lectures in real time to help students not only to review content, but also to see what they might have just missed.

Herzberg explained that students with attention-deficit/hyperactivity disorder may unintentionally lose focus in class and — because college courses are often fast-paced, with information that builds upon itself — quickly get left behind.

“I’ve had many classes where I’ve missed the teacher talking about the homework assignment, or a key point,” said Herzberg, who has ADHD. “Then I’m spending the entire day or even weeks trying to catch up, just because I missed that one important point.”

Herzberg got the idea for Alerty when he was in high school. His sister worked as a paraeducator who assisted students with learning disabilities by sitting with them in class, giving them one-on-one support.

“I wanted to make something that people would want to use as a tool, without drawing attention to themselves,” Herzberg said.

During the COVID-19 pandemic, when classes were being taught asynchronously online, Herzberg liked that he was able to go back and replay the lectures and absorb concepts he may have missed in real time.

“I was able to get better grades and even made the Dean’s List because I was able to go back and replay, slow down, and speed up the videos,” he said.

Alerty is a two-way street. The instructor must use the app in order for students to use it themselves. When the instructor makes an important point, they press a button on the app, which alerts students with a vibration on their phones or tablets. The app also highlights the corresponding part of the transcript in blue.

After class, students can review the lecture and, if necessary, select a portion of the transcript to ask the instructor for clarification. This feature also helps instructors to see where students are struggling over certain concepts.

The app can help many other students as well, including those who have different learning styles, English language learners, and those who have difficulty hearing.

In addition to the TiE award, Alerty earned second place in the College of Business’s Launch Academy competition, and a grant from the 1517 Fund.

Shabanov, who is responsible for the company’s business strategy, marketing, and financial planning, is working on obtaining additional funding.

Mike Bailey, professor of computer science, beta-tested Alerty in one of his classes during spring term. “For those who have difficulty focusing and taking notes in class, I think this could be a game-changer,” he said.

Jonah Siekmann and Yesh Godse A research paper on robotics authored by computer science researchers at Oregon State University was recently named one of the top four out of more than 2,000 accepted submissions at a prestigious conference.

Students Jonah Siekmann and Yesh Godse presented their research findings at the 2021 IEEE International Conference on Robotics and Automation. In their paper, “Sim-to-Real Learning of All Common Bipedal Gaits via Periodic Reward Composition,” they report on their work using simulations to teach two-legged robots how to run, skip, and hop.

The paper is co-authored with Alan Fern, professor and associate head of research in the School of Electrical Engineering and Computer Science, and Jonathan Hurst, professor of mechanical engineering and robotics.

Traditionally, researchers have tried to train bipedal robots to move by first creating a “reference trajectory,” which tells the robot at each moment where its joints and velocities should be. This approach, however, doesn’t work particularly well since it is difficult to figure out the reference trajectories, and it doesn’t take into account the uneven surfaces the robot needs to deal with.

Instead, the researchers’ new approach trains the robot in simulation, and rewards the robot when it is accomplishing the goal, and gives negative rewards when it is not.

“We use an approach that simply specifies constraints on the foot forces and velocities which allows us to specify the different types of gaits and smoothly move between them,” Fern said. “This worked much better than we ever expected.”

Siekmann, a master’s degree student in robotics who earned an honors bachelor’s degree in computer science from Oregon State in 2020, provided some additional insights.

“We were trying to train a neural network to learn various bipedal behaviors from scratch without any kind of motion capture or reference to what those behaviors looked like,” Siekmann explained. “To do this, we used deep reinforcement learning that allows a neural network to maximize a reward function.”

Added Godse, “It turned out that there was a simple mathematical framework for describing the full spectrum of all bipedal gaits and their corresponding reward/cost functions.”

Godse graduated in just three years with a bachelor’s degree in computer science from Oregon State in spring 2021 and began working on robotics research as a freshman.

Both Siekmann and Godse are now working as controls engineers at Agility Robotics, the company co-founded by Hurst that develops the robots used in Oregon State’s Dynamic Robotics Lab.

The Defense Advanced Research Projects Agency (DARPA) has named Margaret Burnett, Distinguished Professor of Computer Science at Oregon State University, to the Information Science and Technology Study Group for a three-year term beginning this summer. The group brings 30 of the brightest scientists and engineers together to identify new areas of development in computer and communication technologies and to recommend future research directions.

Burnett is the second Oregon State member of the study group. Tom Dietterich, Distinguished Professor of Computer Science, a part of the steering committee for the group.

“This is a chance to be a part of making a real impact together with some of the leading minds in science and technology, and change the world for the better,” Burnett said.

Burnett specializes in research at the intersection of human computer interaction and software engineering, and is known for her pioneering work in visual programming languages, end-user software engineering, and gender-inclusive software. She has received recognition from national organizations including the CHI Academy, the National Center for Women and Technology, ACM SIGSOFT, and IEEE Symposium on Visual Languages and Human-Centric Computing.

The Information Science and Technology Study Group was established by DARPA in 1987 to support its technology offices and provide continuing and independent assessment of the state of advanced information science and technology as it relates to the U.S. Department of Defense.

Lizhong Chen, assistant professor of electrical and computer engineering in the College of Engineering at Oregon State University, joins five others this year who were inducted into the Hall of Fame of the IEEE International Symposium on High-Performance Computer Architecture. It is the top venue in the field and there are only 53 inductees in its 26-year history who meet the requirement of having at least eight publications accepted to the symposium.

“I feel honored, as most of the current members in the Hall of Fame are senior researchers who are IEEE and/or ACM Fellows,” said Chen. “I appreciate the recognition as it acknowledges my technical contribution to the computer architecture community in the past decade. It also helps to increase the visibility of Oregon State in this research field.”

Earlier this year, Chen received the Best Paper Runner-Up Award at the 2020 IEEE International Symposium on High-Performance Computer Architecture. He also received the prestigious National Science Foundation CAREER Award in 2018.

Chen is the founder and organizer of the Annual International Workshop on AI-Assisted Design for Architecture. He is a Senior Member of the IEEE and the Association for Computing Machinery, and currently serves as an associate editor of the IEEE Transactions on Computers.

Ni Trieu (’20 Ph.D., Computer Science) was recognized for her work in an area of cryptography called private set interaction. It allows two entities to compare databases to find items in common without leaking other information such as passwords.

Trieu received the dissertation award from the School of Electrical Engineering and Computer Science for research that improved the speed and security of private set interaction. She also developed the first practical techniques to compare more than two sets of data.

“Ni has a great aptitude for research, and a compelling vision of how cryptographic tools can protect the privacy of everyday people,” said Mike Rosulek, associate professor of computer science in the College of Engineering. “She matches her technical aptitude with an equal measure of hard work and persistence.”

Trieu grew up in Vietnam and received a scholarship to do her undergraduate studies in Russia at St. Petersburg State Polytechnic University. During her time there, she developed an interest in theoretical computer science, including cryptography, which she describes as a bridge between theory and practical applications.

As a student at Oregon State, Ni also spent several summers as a research intern at Bell Labs, Visa Research, and Google. She is currently a postdoctoral researcher at University of California, Berkeley. She will be joining Arizona State University as an assistant professor this fall.
