Jacob Cook is the definition of an overachiever. This spring he had the rare distinction of graduating with not one but two honors bachelor’s degrees from the College of Engineering at Oregon State University, in bioengineering and electrical and computer engineering, as well as a minor in computer science.

“Successful completion of a dual degree requires unparalleled dedication and discipline to meet requirements for both programs,” said Matthew Johnston, assistant professor of electrical and computer engineering.

Cook’s achievements were recognized with the Burgess/Tektronix Award, given each year by the College of Engineering to a senior who has demonstrated exceptional participation in activities beyond academic performance. 

In addition to excelling in two challenging academic programs, Cook also completed a MECOP internship, participated in research for two different labs, served as both an undergraduate learning assistant and a resident assistant, and was an active community member.

“Jacob’s dedication and productive contributions to multiple hands-on research programs is remarkable, and it speaks to his future potential for contributions to the industry,” Johnston said.

Although he put in a huge amount of work on his own, Cook says he was lucky to have had tremendous support from his family. 

“Both my parents are computer engineers who taught me great perseverance and an intense work ethic,” he said. “They raised me to do my best and encouraged me to go to college. Likewise, my grandfather was a businessman who taught me the importance of leadership and interpersonal skills for success. I cannot imagine where I would be without my family, and I wouldn’t have received this award without their help.”

The Burgess/Tektronix Award was initiated in 1990 to honor Fred Burgess, past dean of the College of Engineering. Cook received a plaque and a check for $500 and will be recognized at the fall College of Engineering Celebrate Excellence event in the fall.

Eta Kappa Nu at Oregon State University is an honor society for electrical and computer engineering majors through IEEE. At the end of each school year, the club recognizes two students with awards. This year winners were Yeojin Kim for the Robert Short TA of the Year award, and Noah Koontz for the Sophomore of the Year award.

Noah Koontz has been fascinated with the fusion of hardware and software from an early age. In middle school he got his first Arduino and attempted to build an open-source laser tag system with it.

“I’ve been a maker ever since,” he said.

At Oregon State, he has been working at the Open Sensing Lab, which has allowed him to apply his passion and skills to solve real-world problems in agriculture — building internet-connected devices for farmers and researchers to monitor their crops.

“I will continue to seize opportunities to work with embedded systems and solve real-world problems, hopefully having fun along the way,” Koontz said.

Laurel Hopkins was awarded the Future Investigators in NASA Earth and Space Science and Technology fellowship to support her doctoral research to improve species distribution models. The models link environmental variables to species occurrences and are useful tools for science and conservation.

Hopkins, a graduate student of computer science in the College of Engineering at Oregon State, was inspired by a class project in which she was modeling butterfly occurrences. She realized she could improve species distribution models using deep learning methods to analyze satellite images.

“Deep learning methods are incredibly powerful in extracting semantic information from images, meaning these techniques are well suited to analyze remotely sensed data,” she said.

She will use a large dataset of NASA Landsat images to train deep networks which, based on preliminary results, she expects will produce habitat summaries that are more descriptive than traditional methods, and lead to more informative species distribution models.

 Hopkins will publicly share the image library and deep network architectures so other researchers can use them to advance ecological research.

The award is for $135,000 to support her research under the guidance of Rebecca Hutchinson, assistant professor of computer science, and of fisheries and wildlife.

“I am thrilled to be working towards better understanding how we can limit our footprint and help support biodiversity,” Hopkins said. “It is phenomenal to get this support from NASA because it means that they understand the need and importance of this area of work.”

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.

Support with teaching from the undergraduate learning assistants was appreciated even more than usual spring term, as all classes switched to remote teaching due to the coronavirus pandemic. In recognition of the students’ efforts, a new award was created in the School of Electrical Engineering and Computer Science. Greg Healy and Nadia Najim received the awards this year which included a certificate and $500.

Greg Healy holds bachelor’s and master’s degrees in civil engineering and is pursuing a degree in computer science to become a full-stack web developer. He has been the learning assistant for the web development course for the online degree program in computer science for postbaccalaureate students.

In course evaluations, the students said Healy was as the most influential component of their success. In addition to being extremely responsive to student questions, he also created video demonstrations to walk students through more challenging content. When asked by the course instructor, Eric Ianni, to review assignments and suggest improvements, Healy went one step further and designed several assignments that built to a towards a final assignment.

“Greg is a once in a lifetime undergraduate learning assistant,” Ianni said.

Nadia Najim is a bachelor’s student in applied and computational mathematics. She has been an undergraduate learning assistant for large electrical engineering courses and served as the head assistant where she managed a team of up to 12 other assistants. Najim was nominated by four faculty who wrote in their letter that she “made sustained and absolutely outstanding contributions to the education of more than 2,000 undergraduate students.”

By creating reusable content, Najim has made an impact beyond her own interactions with students. She generated weekly topical material, including group and individual practice problems, as well as guidance and training for fellow assistants on best practices, tips, and tricks for approaching each course topic.

Najim’s skills were especially appreciated by Pallavi Dhagat, professor of electrical and computer engineering, who taught engineering fundamentals for the first time in spring term.

“All through the term, she kept ahead of me, alerting me to what was coming next in the recitation sessions, creating sample problems for help sessions before the midterm and final exams, rallying the other learning assistants and students during stressful times in the term, advising me on concepts she felt I could reinforce in my lectures and giving me valuable feedback on the length and difficulty of my exams,” Dhagat said.

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.

Computational notebooks—such as Azure, Databricks, and Jupyter—are a popular, interactive paradigm for data scientists to author code, analyze data, and interleave visualizations, all within a single document. Nevertheless, as data scientists incorporate more of their activities into notebooks, they encounter unexpected difficulties, or pain points, that impact their productivity and disrupt their workflow. Through a systematic, mixed-methods study using semi-structured interviews (n = 20) and survey (n = 156) with data scientists, we catalog nine pain points when working with notebooks. Our findings suggest that data scientists face numerous pain points throughout the entire workflow—from setting up notebooks to deploying to production—across many notebook environments. Our data scientists report essential notebook requirements, such as supporting data exploration and visualization. The results of our study inform and inspire the design of computational notebooks.

Congratulations to the 512 students majoring in electrical and computer engineering or computer science who made the College of Engineering Dean’s List for winter term of 2020! These undergraduate and postbaccalaureate students achieved better than a 3.75 GPA with at least 12 credits.
