Guy Sella
guy-sellags2747 at columbia.edu

Guy received a B.Sc. in Physics and Mathematics from Tel Aviv University, a M.Sc. in Neural Computation from the Hebrew University (with Itamar Pitowsky and Eva Jablonka), and a Ph.D. in Mathematics from Tel Aviv University (with Ilan Eshel and Marc Feldman, Stanford University). Before joining Columbia University, he was a faculty member at Hebrew University (Israel) and a visiting Professor at Stanford University and the University of Chicago.


Yuval Simons

yuval-simonsGraduate student

Yuval received a B.Sc. in Physics from the Hebrew University (Israel) and a M.Sc. in solid-state physics from the Weizmann Institute of Science (Israel), before joining the lab in 2012. His earlier work focused on the effects of recent demographic history on the burden of deleterious mutation in human populations. He now combines modeling and statistical inference to study the processes that underlie quantitative genetic variation in humans.


 Guy Amster

img_0263-1Graduate student

Guy received a B.Sc. in Statistics and Mathematics and a M.Sc. in Mathematics from the Hebrew University (Israel) and worked in the high-tech industry before joining the lab in 2013. He works on diverse topics, including modeling life history effects on neutral patterns of polymorphism and divergence (e.g., to explain differences between X and autosomes and the mutational slowdown in apes) and developing methods to infer changes in mutation rate using polymorphism data.

 

 


 David Murphy
davidGraduate student

David received his B.Sc. in Neuroscience from Brandeis University in 2009, then worked as a research assistant in the Hatten lab at Rockefeller University. He joined the graduate program in Biological Sciences at Columbia in 2013. His research is focused on the effects of linked selection on diversity levels in the human genome.

 

 


Laura Hayward

laura-hayward-1Graduate student

Laura received a B.Sc. in Mathematics from Cape Town University (South Africa) in 2011 before joining the Ph.D. program in Mathematics at Columbia. Before joining the lab, she worked on evolutionary game theory. She now works on modeling polygenic adaptation.

 

 


Jeremy Berg
jeremyPostdoc

Jeremy received his B.Sc. in Biology from the University of Wisconsin. He was a graduate student at Graham Coop’s lab at UC Davis, where he worked on methods to detect polygenic selection in humans and on modeling selective sweeps from standing genetic variation. He joined the lab in 2016 and is working on elucidating the causes of quantitative genetic variation.


Alumni

Etam Benger

Former M.Sc. student

Etam received his B.Sc. and M.Sc. in Mathematics from the Hebrew University (Israel). During his M.Sc., he developed a mathematical model that described the effects of changing selective pressures on substitution patterns. Etam now works as head of research at Taykey (Israel).


Luba Broitman
lubaFormer M.Sc. student, jointly supervised by Ran Nathan

Luba received her B.Sc. in Physics and M.Sc. in Ecology and Evolution at the Hebrew University (Israel). During her M
.Sc., she used mathematical models and computer simulations to study how characteristics of the environment affect animal movement.

 


Eyal Elyashiv
eyalFormer M.Sc. and Ph.D. student

Eyal received a B.Sc. in Mathematics and Computer Science from Tel Aviv University (Israel), before joining the lab for his M.Sc. and Ph.D. in Ecology and Evolution at the Hebrew University (Israel). His masters work focused on characterizing genome-wide shifts in the efficacy of purifying selection between populations and species of yeasts. For his doctoral research, he developed and applied methods to infer the parameters of linked selection from patterns of genetic diversity. Eyal is now a research scientist at Ancestry.com.


Arbel Harpak

arbel-harpakFormer M.Sc. student

Arbel received his B.Sc. in Physics and Mathematics at the Hebrew University (Israel), before joining the lab for his M.Sc. in Ecology and Evolution at the Hebrew University. For his masters, he developed models for genetic diversity levels in evolutionary experiments with bacteria. He is now pursuing his Ph.D. with Jonathan Pritchard, at Stanford University. 


Oren Kolodny

oren-kolodnyFormer M.Sc. student

Oren received his B.Sc. in Physics before joining the lab for his M.Sc. in Ecology and Evolution at the Hebrew University. His masters focused on methods for inferring the parameters of adaptation from patterns of genetic variation. He then completed a Ph.D. in Biology with Arnon Lotem at Tel Aviv University (Israel) and is now a postdoc with Marc Feldman at Stanford. 


Shmuel Sattath

289e85bFormer research scientist

Shmuel received a B.Sc. in Physics and Mathematics, a M.Sc. in Mathematics (with Azriel Levi), and a Ph.D. in Psychology (with Amos Tverski) from the Hebrew University (Israel). He was a co-founder of Pilat, and was a part-time research scientist in the lab from 2007-2013. Shmuel’s work focused on learning about adaptation in Drosophila species using genetic variation data. He is currently Chairman and Founder of Mobeeart.com (Israel).
