Carlos Eduardo G. Amorim

eduardo_croppedPostdoctoral Researcher

cg2827 at

Eduardo holds a B.Sc. in Biological Sciences and a M.Sc. in Animal Biology from the University of Brasília (Brazil). He completed his Ph.D. in Genetics with Prof. Francisco Salzano at the Federal University of Rio Grande do Sul (Brazil) in 2013 working on the influence of demographic, cultural, and adaptive processes on the genetic diversity of Amerindians during the settlement of the New World. His postdoc project, supported by a Science Without Borders fellowship from Brazil, is focused on understanding the role of balancing selection in shaping the genetic diversity of modern humans and other primates.

Chen Chen

Graduate Student

cc3499 at

Chen has an undergraduate degree in Biological Sciences from  Tsinghua University, China (2012). She is a graduate student in the Biological Sciences program at Columbia University. She is currently studying variation in the germline mutation rate as a joint student with Molly Przeworski at Columbia and Joe Pickrell at the New York Genome Center.

Ziyue Gao

Ziyue_CroppedGraduate Student


Ziyue received a B.A. in Biology from Tsinghua University in Beijing, China (2010). She is a graduate student in the Genetics, Genomics and Systems Biology program at the University of Chicago and the recipient of the Biological Sciences Division Harper Dissertation Fellowship. She has worked on modeling and identifying long-lived balanced polymorphisms, and is now focused on estimating neutral and deleterious mutation rates in humans.

Priya Moorjani

priyaPostdoctoral Researcher

pm2730 at

Priya has an undergraduate degree in Computer Engineering from University of Mumbai and M.S. in Bioinformatics from George Washington University. She received her Ph.D. (2013) in Genetics from Harvard University (advised by David Reich and Nick Patterson). During her dissertation, she developed novel methods and approaches for analyzing genomic data to learn about population history, particularly focusing on populations of mixed ancestry such as West Eurasians and South Asians. During her postdoc, Priya is interested in investigating meiotic recombination and germline mutation in humans.

Abhi Ratnakumar

Postdoctoral Researcher

ar3506 at columbia dot edu

Abhi has undergraduate degrees in Software Engineering and Science from the University of Sydney. She worked on comparative genomics projects as a Bioinformatics research assistant at CSIRO, then moved to Uppsala University to work on dog genetics, identifying selective sweeps associated with breed creation and domestication. Her postdoc project focuses on the study of natural selection in contemporary human populations.

Sonal Singhal

ss4776 at columbia dot edu

Sonal graduated with her B.A. in Biology from Washington University in St. Louis and with her Ph.D. (2013) from University of California, Berkeley, advised by Craig Moritz. In her dissertation, Sonal studied speciation and hybridization in five co-occurring hybrid zones, all of which formed between Australian rainforest lizards. For her postdoctoral research, she is studying the evolution of recombination in wild populations of birds.
