Current Lab Members

Molly Przeworski

Dept. of Biological Sciences
Dept. of Systems Biology

mp3284 at

Molly received a B.A. in Mathematics from Princeton University and a Ph.D. from the Committee on Evolutionary Biology at the University of Chicago, working with Brian Charlesworth and Dick Hudson. Her postdoc was in the group of Peter Donnelly in the Statistics Dept. of the University of Oxford, and was followed by a two year stint as a research scientist at the Max Planck Institute for Evolutionary Anthropology. Before moving to Columbia University, she was a faculty member at the University of Chicago (where she was also a Howard Hughes Medical Institute Early Career Scientist) as well as, briefly, at Brown University.

Ipsita Agarwal

Graduate Student

ia2337 at

Ipsita has an undergraduate degree in Biology and Economics from Amherst College (2013). She is a Ph.D. student in the Biological Sciences doctoral program. Her research focuses on human genetics, including sex differences in human germline mutation and polygenic scores.


Zachary Baker

Graduate Student

ztb2002 at

Zach has an undergraduate degree in Biological Sciences from Cornell University where he concentrated in Genetics, Genomics and Developmental Biology (2014). He is a Ph.D. student in the Integrated Program in Cellular, Molecular and Biomedical Studies doctoral program. His research focuses on the evolution of recombination in vertebrates.

Zachary Fuller

Postdoctoral Researcher

zlf2101 at

Zach has an undergraduate degree in Biology from Creighton University and received his PhD in Biology at Penn State (2017) where he worked with Steve Schaeffer. His dissertation focused on investigating the mechanisms establishing chromosomal inversions in populations of Drosophila, as well as analyzing adaptive evolution in African honey bees. For his postdoc, Zach is investigating the dynamics of deleterious alleles in humans, funded by an NRSA postdoctoral grant, as well as the population genetics of coral.

Arbel Harpak

Postdoctoral Researcher

ah3586 at

Arbel studies questions linking genetic variation and evolution: What are the major forces guiding the evolution of populations? How do molecular mechanisms shape genetic variation? How does natural selection act on many traits and on many genes simultaneously? Arbel holds B.Sc. degrees in Mathematics and Physics, M.S. degrees in Ecology/Evolution and Statistics and–most recently–a Ph.D. in Biology working with Jonathan Pritchard as a CEHG fellow at Stanford University. Arbel is a Junior Fellow at the Simons Society of Fellows.

Carla Hoge

Graduate Student

crh2152 at

Carla studied Biology and Biochemistry at the University of Pennsylvania, where she received her undergraduate and masters degrees (2017). She is currently a PhD student in the Biological Sciences doctoral program and a recipient of an NSF pre-doctoral fellowship. Her research in the lab focuses on the evolution of recombination in vertebrates.

Luke Sarre


crh2152 at

Luke is interested in the relationship between phenotypes, variation, and the evolutionary forces that cause them. He graduated from the University of Sheffield with a Bachelors (2016) and Masters (2017) degree in Molecular Biology, and worked at the Salk Institute of Biological Sciences exploring polymer synthesis in plants. He is now working as a technician between the Przeworski and Andolfatto labs. .

Jihanne Shepherd


crh2152 at

Jihanne is a current Science Research Fellow of the Columbia College class of 2021 and has previously worked in the Cornish lab at Columbia on characterizing promoters in yeast. She is pursuing a major in Biochemistry and a concentration in Computer Science in the Department of Biological Sciences and now continues undergraduate research at the Przeworski lab. .

Felix Wu

Graduate student

flw2113 at

Felix has an undergraduate degree in Organismic and Evolutionary Biology from Harvard University (2014). He is a Ph.D. student in the Integrated Program in Cellular, Molecular and Biomedical Studies doctoral program. He currently works on estimating mutation rates in primates. Outside of the lab, Felix is interested in music and cooking, but he swears that he doesn’t sing Verdi in the kitchen.
