Sarah Cobey

Principal Investigator ·

Sarah is an assistant professor in the Ecology & Evolution Department at the University of Chicago.

Kangchon Kim

Postdoctoral Researcher ·

Kangchon is a postdoc at Cobey lab. She received her PhD in Evolutionary genetics from Ewha Womans University, Seoul, Korea and studied computer science for BS at the same university. She is interested in population genetics of viruses and antibodies and host-pathogen coevolution.

Phil Arevalo

Postdoctoral Researcher ·

Phil is a postdoc at Cobey lab. He completed a Bachelors degree in Applied Mathematics from Brown University and received his PhD in Microbiology from MIT. Phil is interested in exploring the link between the history and processes involved in adaptive immunity and the population-level dynamics of influenza.

Frank Wen

PhD Student ·

Frank is a fourth-year MSTP student at the University of Chicago, from which he graduated in 2013 with a BA in biology and a BS in biological chemistry. His current work examines the effects of vaccines on the evolution of seasonal influenza.

Marcos Vieira

PhD Student ·

Marcos moved to the University of Chicago for his PhD studies after completing his Master's in Ecology & Evolution (Universidade Federal de Goiás) and his BS (Universidade Federal do Ceará) in Biology in Brazil. He's currently interested in the coevolutionary dynamics of pathogens and antibody repertoires, and his background interests include ecological networks and a bit of evolutionary behavioral ecology.

Rahul Subramanian

PhD Student ·

Rahul Subramanian is a first-year PhD student at the University of Chicago in the Department of Ecology and Evolution. He is interested in understanding the effect of prior influenza infection history on antibody responses and the larger interplay between past infection histories, seasonal vaccination, and antibody responses. He enjoys combining his love of engineering, immunology, and public policy by utilizing mathematical models to understand infectious disease evolution. He received a B.S.E. in Electrical Engineering from Princeton University in 2015.

Sylvia Ranjeva

PhD Student ·

Sylvia is a sixth-year MSTP student at the University of Chicago and Pritzker School of Medicine, pursuing a PhD through the Department of Ecology and Evolution. She is co-advised by Greg Dwyer. Broadly, she is interested in mathematical modeling of human disease processes with implications in public policy. Sylvia received Bachelor of Science degrees in engineering science and French literature from Pennsylvania State University in 2012.

Graham Northrup

Research Assistant ·

Graham is a fourth-year undergraduate at The University of Chicago majoring in Computational and Applied Mathematics. He is interested in a wide range of questions at the intersection of biology and mathematics, and is currently working to build a computational model to help understand B cell immunodominance.

Rohan Dandavati

Research Assistant ·

Rohan is a third-year undergraduate student at the University of Chicago, planning to major in Mathematics and Computer Science
