Current Members


Andrew Oberst, PhD

Professor of Immunology

Andrew graduated from Amherst College and pursued his graduate studies in Europe, in a collaborative program between the Universities of Rome and Paris. He completed postdoctoral training at St. Jude Children’s Research Hospital in Memphis, TN. He joined the Department of Immunology as an Assistant Professor in 2012, and was promoted to Associate Professor in 2018 and Professor in 2023. He definitely doesn't have more grey hair now than he did when this photo was taken.


Joshua M. Ames, PhD

Senior Fellow

Josh earned his PhD from the Graduate Education in Medical Sciences program at the University of Illinois at Chicago, where he studied the immune response provoked by herpesvirus infection of the eyes and nervous system. He joined the Oberst Lab in 2021. He's supported by a Helen Hay Whitney postdoctoral scholarship and a Burroughs-Wellcome PDEP award.  Josh makes amazing home-made hot sauce, which he shares with the lab. 


Suny Chavarria

Graduate Student

Suny earned her undergraduate degree from the City College of New York, and gained research experience at Mt. Sinai in New York before joining the Oberst Lab in 2021. She's supported by UW Cellular and Molecular Biology training grant. 


Lan H. Chu, PhD

Senior Fellow

Lan earned a Ph.D. from the Driskill Graduate Program in Life Sciences at Northwestern University, where she discovered a role for oxidized phospholipids in controlling inflammasome activation. Lan started her postdoctoral training in the Oberst Lab in 2019. Observations indicate that Lan is largely nocturnal, typically working from mid-afternoon 'till the wee hours of the morning.

Cassidy Hagan

Graduate Student

Cassidy completed her undergraduate studies at Colorado State University, and joined the Oberst lab in 2019. She is working towards a PhD in immunology. Cassidy once biked from Seattle to the Cascades towing a trailer full of skis, skied all day, then biked home, all for "fun." 


Sigal Kofman

Graduate Student

Sigal graduated from the University of California, Irvine with a BS in biology. She is currently pursuing a PhD in immunology. Sigal joined the Oberst lab in 2018.


Aletta Li

Undergraduate Student

Aletta is a fourth-year student at UW majoring in biochemistry, and she joined the Oberst lab in March of 2020. Aletta used to love chocolate, but has eaten so much of it over the years that she's now sick of it - she now snacks on (and sometimes shares!) a variety of other treats, including matcha-flavored KitKats! 


Katrina Lichauco

Graduate Student

Katrina graduated from the University of Arizona with dual degrees in Biochemistry and Molecular & Cellular Biology. Katrina joined the Oberst Lab in the summer of 2020.


Megan S. Molina, PhD

Senior Fellow

Megan earned a Ph.D from the University of Arizona, where she studied the effects of chemotherapeutic agents on native and transplanted immune cells. Megan joined the Oberst lab in 2021. Megan is supported by a CRI Irvington fellowship. Megan's commitment to research is so strong that she literally has a piece of data tattooed on her arm.

Valerie Sheehan

Lab Manager

Valerie graduated from UW with a degree in Biology in 2022, and joined the Oberst Lab the same year. To our surprise, and only after hiring her, we learned that Valerie was once deported from Ireland!
