John Novembre


I got my start in this field through a combination of enjoying computer programming as a hobby and thinking about evolution as one of the world’s most fascinating natural processes. Now, my main research tackles statistical and theoretical problems to help enable discoveries about evolutionary processes and the nature of disease variation. Much of that work is in the context of human genetic variation, which is doubly fascinating because of the connections to fields like linguistics, archaeology, and history. For my training, I earned my undergrad degree in biochemistry at the Colorado College, studied for my PhD in Integrative Biology (with a designated emphasis in Computational Biology & Genomics) at UC-Berkeley under Montgomery Slatkin, and did a postdoc in Human Genetics at Chicago with Matthew Stephens. My first faculty position was in the Ecology and Evolutionary Biology Department at UCLA and then I returned to the University of Chicago in 2013. Outside of my work I enjoy travel, music, and a variety of different outdoor sports.

Xinyi Li

PhD Student in the Genetics, Genomics and Systems Biology Program

Xinyi is interested in studying natural selection and the evolution of complex traits to increase our understanding on disease mechanism, especially immune traits. Prior to joining the lab, Xinyi worked on statistical method development for estimating disease heritability in admixed populations.

Ahmed Selim

PhD Student in the Biophysics Program

Ahmed is broadly interested in utilizing methods from physics and probabilistic modeling to understand evolving populations, especially scale-dependent processes. Prior to joining the lab, he worked on the ecology and evolution of microbial metabolic networks.

Maggie Steiner

PhD Student in the Human Genetics Program

Maggie is interested in studying spatial processes in evolution and impacts on human disease traits. Her current research focuses on the impact of geographic sampling and dispersal on rare variant ascertainment and models for the spatial spread of adaptive alleles. Prior to joining the lab, she graduated from George Washington University with a BS in Mathematics and studied evolutionary genomics in retroviruses.

Hannah Moots

Neubauer Postdoctoral fellow joint with Maanasa Raghavan, David Schloen, and James Osborne

Hannah’s PhD training was in archaeology and genetics, specializing in questions of connectivity in the Mediterranean. For her postdoctoral fellowship, she is leading interdiscplinary projects with continued emphasis on themes of temporal changes in connectivity.

Hao Shen

Postdoctoral fellow

Hao’s expertise is in theoretical population genetics and statistical genetics. His PhD work included an analysis of causal inference in the presence of direct and indirect genetics effects. For his postdoctoral research, he will be investigating models of time-varying migration rate in spatial population genetics.

Luke Anderson-Trocmé

Postdoctoral fellow (arriving Jan 2023)

Luke is interested in visualizing the spatial distribution of genetic variation. His PhD work included the analysis of genetic, genealogical and geographic data from Quebec.


After more than ten years now as a lab, we have an even spread of alumni that have gone into academics and industry. Thus far, geographically our alumni can be found in the United States, Mexico, Canada, Switzerland, and Germany. While we work in a university setting and train ourselves in the practice of research and teaching, this prepares our alumni for a broad set of careers.
