Guy Amster

img_0263-1Former Graduate 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. During his Ph.D., Guy worked on diverse topics, including modeling life history effects on neutral patterns of genetic diversity within and between species, e.g., to explain differences between X and autosomes and the molecular clock in apes. He is now a Staff Machine Learning Software Engineer at Flatiron Health.


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).


Jeremy Berg

Jeremy received his B.Sc. in Biology from the University of Wisconsin. He was a graduate student with Graham Coop’s at UC Davis, where he worked on methods to detect polygenic selection in humans and on modeling selective sweeps from standing genetic variation. For his postdoc, Jeremy investigated population genetic models of complex diseases. He is now an Assistant Professor at the University of Chicago.


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 how selection affects patterns of neutral genetic diversity. Eyal is now a research scientist at Ancestry.com.
