Matt Barber

Assistant Professor of Biology

Matt grew up in Maryland and Japan before heading to New York to pursue his undergraduate degree in molecular biology at Colgate University. He completed his Ph.D.  in the labs of Or Gozani and Katrin Chua at Stanford University studying the biochemistry and cellular functions of mammalian protein deacetylases. After developing an interest in evolutionary biology, Matt went on to investigate host-microbe genetic conflicts in Nels Elde’s lab at the University of Utah. He joined the University of Oregon as an assistant professor in September 2016. Outside of lab Matt enjoys spending time with his family and exploring the beautiful Pacific Northwest.


Kristin Kohler

Research Associate & Lab Manager

Kristin grew up in the small town of Jackson in Northern California and obtained her bachelor’s degree in biology at the University of the Pacific. During her time at Pacific she worked in the laboratory of Craig Vierra where she identified silk genes of the Black Widow spider. She completed her Ph.D. in the lab of David Schatz at Yale University studying the targeting of Somatic Hypermutation in activated B cells. In the Barber lab Kristin applies her knowledge of immunology to study several projects at the interface of evolution and bacterial-host interactions. Outside of work Kristin enjoys hiking with her dog, trail running and baking.

Postdoctoral Fellow


Omoshola Aleru

Ph.D. Student
NIH T32 training grant recipient

Omoshola (Shola) grew up in Fresno, California and obtained her bachelor’s degree in biology at California State University Fresno in 2017. She is a current Biology Ph.D. student in the Institute of Ecology and Evolution and is excited to integrate her knowledge of microbiology in studying the evolution of host-microbe associations.


Nicole Paterson

Ph.D. Student
NIH T32 training grant recipient

Originally from the San Francisco Bay Area, Nicole did her undergraduate research in the lab of Kenneth Stedman on a NASA-funded project on acidophilic thermo-stable archaeal proteins. Subsequently she worked in the lab of Curt Machida at OHSU testing the bactericidal properties of bioactive resins on S. mutans biofilms, and then in the lab of Jason Taylor at the Portland VA studying immunological defects in a mouse model of Fanconi anemia. She also has a Master’s degree from work done on spindle orientation in the lab of Ken Prehoda at UO. Nicole is excited to combine her research on the immune system with her early experience in evolutionary ecology to study how immune receptors evolve new functions in primates. She loves animals and almost became a veterinarian, in her spare time she serves the public on the City Council Toxics Advisory Board and hikes mountains with her dog.


Ryan Sayegh

Research Assistant

Ryan grew up in Abu Dhabi in the United Arab Emirates, and his family is originally from Lebanon. He is a recent graduate of the University of Oregon, where he attained a Bachelor of Science degree in Biology, with minors in Chemistry and Theatre Arts. During his undergraduate degree, he worked in Annie Zemper’s laboratory where he studied the roles of proteins in the colonic epithelium of mice. Ryan is incredibly excited to learn about the evolutionary processes shaping host-microbe interactions. Ryan enjoys drawing, going on hikes, and cooking.


Dimitra Fellman

Undergraduate Student

Dimitra grew up in Westchester, NY before moving to Portland, OR at the age of 14. Growing up, she was always interested in science, but discovered her passion for infectious diseases and global health in high school. She is now a student at the University of Oregon working towards a B.S. in biology as well as minors in global health and dance. Dimitra is excited to learn and explore as she continues through college and beyond. She enjoys spending time with friends and family, dancing and singing along to her favorite songs.
