Graduate Students

Jared Johnson, PhD student  (co-advised by Chris Curtin)

Jared is a Food Science Ph.D. student working on characterizing the cheese facility microbiome. He started working with Joy and Chris Curtin immediately following his master’s degree, which explored the role of ‘wild yeast’ during the early stages of winemaking. His interests are primarily in the microbiology of fermented foods and beverages. Jared also earned his bachelor’s degree from OSU studying food science with a focus on fermentation. When he’s not in the lab, he spends most of his time exploring the Oregon outdoors with his family. Some of Jared’s favorite pastimes are fishing, rockhounding, and cooking. He also enjoys writing and playing music, and spent several years as a touring musician before starting his college education.

She received her BS in biology from Ohio State University and after graduation, spent a year in AmeriCorps as an English tutor to the immigrant and refugee populations of Dayton. She then moved to Los Angeles where she earned a MA and a teaching credential in Secondary Science Education from California State University, Los Angeles. She taught public high school chemistry and biology in downtown Los Angeles for four years before returning to school at California State University, Northridge for a Master’s in Public Health. Stephanie is currently a Food Science Ph.D. student particularly interested in extension work and education. Outside of her studies, Stephanie is interested in coffee, traveling, cooking, sewing clothes and quilts, fiber art, reading, and spending time with her family.


Immanuel Rodriguez, MS student

Immanuel was born and raised in Riverside, California. He received a BS in Microbiology from Weber State University, in Ogden, Utah. He is pursing an MS in Food Science and Technology at OSU. Immanuel has a wonderful wife and 4 children. He loves to mountain bike, hike, and cook.


Carson Davis, MS student

Carson is from Ogden, Utah where he has lived most of his life until attending graduate school.  He finished his undergrad at Weber State University in microbiology. He has an agricultural background as well, growing up on a family farm and beef ranch. In his free time he likes to go to semi truck shows, mountain bike, hike, and go on drives just for the views. Carson has a passion for growing things, he still has a patch of blackberries and raspberries that his family is tending to in his absence. Currently he is working on a masters in Food science, evaluating organic and conventional dairy products.


Rebecca Bland, MS student (co-advised by Jovana Kovacevic)

Rebecca is a Food Science Masters student studying Listeria spp. in food processing environments with interest specifically in produce safety. Following her first year at the Corvallis campus of OSU, Rebecca will continue her research at the Food Innovation Center in Portland under Dr. Jovana Kovacevic.

Originally from San Diego, CA Rebecca received her bachelor’s degree in Food Science from Cal Poly in 2019.


Brandon Riesgaard, MS student 

Brandon grew up in Nebraska before moving to Oregon to earn a Culinary Arts degree from OCCI in Coos Bay. After a 15-year career as a professional chef he returned to college to pursue a degree in Food Science at Oregon State University.  During his undergraduate he worked in the OSU creamery where he helped to standardize a new Gouda cheese recipe. He is now working to earn a MS in Food Science focusing on pathogens in cheese.  

Brandon is an outdoors enthusiast, avid gardener, live music snob, mushroom forager, and occasional surfer.


Alejandro Torres Beauchamp, MS student 

Alejandro is from the island of Puerto Rico; he has lived all his life in the capital of San Juan and recently finished his BS in Microbiology at the Interamerican University of Puerto Rico. Alejandro is now pursuing a MS in Food Science and technology at OSU. In the future, Alejandro wants to work in a Food Safety oriented environment where he can combine his passion for Microbiology with his knowledge about Food to solve future problems that may arise from the industry itself. In his free time, he is mostly listening to music (he is an audiophile) and doing road trips around Puerto Rico. Now that he is in Oregon, he wants to explore the beautiful outdoors that surround Corvallis.


Andrea Domen, MS student
