My name is Arslan Zaidi and I’m a statistical geneticist at the University of Pennsylvania. I’m interested in understanding how demographic processes such as admixture, population bottlenecks, expansions, non-random mating, and selection shape genetic variation underlying complex traits in humans.
I am from Pakistan, where I completed my undergraduate degree in genetics from the University of Karachi under the advisorship of Dr. Ahsan Vahidy. My graduate work, which I did with Mark Shriver at Penn State, focused on studying the evolutionary genetics of physical traits such as skin pigmentation and 3D facial shape. Then I did a postdoc with Kateryna Makova, also at Penn State, where I studied the transmission dynamics of mitochondrial DNA heteroplasmies in human families, and mito-nuclear interactions in admixed populations. Currently, I’m a postdoc with Iain Mathieson at The University of Pennsylvania. I’m studying how human demographic history and population stratification impact inference in large-scale genome-wide association studies. I am also investigating whether or not (and to what extent) mitochondrial-nuclear epistasis contribute to phenotypic variation in humans.
