Matt grew up in Maryland and Japan before heading to New York to pursue his undergraduate degree 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-pathogen 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 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.

Mary Darby, a native of Mississippi, grew up in Oxford, MS and attended Mississippi State University. After graduating with a bachelor’s degree in biological sciences, she joined the lab of Brian Akerley at the University of Mississippi Medical Center. Mary Darby studied immune evasion mechanisms and sialic acid-mediated resistance in nontypeable Haemophilus influenzae and was awarded her Ph.D. in Microbiology and Immunology in May 2020. As a new member of the Barber lab, Mary Darby is excited to extend her knowledge in bacteriology to study how host-microbe interactions shape immunity and bacterial adaptation. In her free time, she enjoys running and exploring the area with her husband and dog.

Caitlin is a northeast native and grew up in New Hampshire. After receiving her BS in Biology from Stonehill College in Massachusetts, Caitlin returned to New Hampshire for graduate school at Dartmouth. While at Dartmouth, she joined Robert Cramer’s lab where she investigated the influence of hypoxia on filamentous fungal biofilms and pathogenesis utilizing the human fungal pathogen Aspergillus fumigatus. She was awarded her PhD in Microbiology and Immunology in April 2020. Caitlin’s graduate work leveraging natural strain heterogeneity and experimental evolution got her interested in the adaptation of host-associated microbes. In the Barber lab, Caitlin is excited to investigate how host-microbe and micro-microbe interactions shape microbial adaptation. Outside of lab, Caitlin can be found exploring in the mountains, trail running, or enjoying a local sour beer.

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.

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.

Killian is originally from Spokane, WA and obtained his undergraduate degree from Eastern Washington University, where he worked with Dr. Andrea Castillo. After that, Killian went on to work at Fred Hutchinson Cancer Research Center as an NIH-PREP post-baccalaureate student in the lab of Harmit Malik. There he worked alongside Tera Levin studying host-pathogen interactions between Legionella and amoeba. Killian is currently a graduate student in the Institute of Ecology and Evolution, and is interested in the evolution of host-pathogen interactions. In his free time, Killian enjoys listening to rap music, running, and cooking.

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.
Clara grew up in Portland, Oregon and attended University of California, Los Angeles, where she studied the effects of aminoacyl-tRNA synthetase editing deficiency on Escherichia coli viability, before earning her Bachelor of Science degree in Biology at University of Oregon in 2020, where she researched 3D genome organization of Schizosaccharomyces pombe. She is currently a research assistant in the Barber and Kern-Ralph labs, and is interested in spatial population genetics, coevolution, and host-pathogen interactions (and hopes to combine all three someday!) In her spare time, she’s usually in the wilderness, drawing, or spending quality time with her bearded dragon.
