Parul is an Assistant Professor at the University of North Carolina, Chapel Hill, in the Department of Biology and the Department of Genetics, with an affiliation in the Integrative Program for Biological and Genome Sciences. Before that, she was a postdoc at Arizona State University, advised by Jeffrey D. Jensen, and frequently collaborated with Brian Charlesworth from the University of Edinburgh. She earned her PhD in the Evolution, Ecology, and Behavior program at Indiana University, Bloomington, under the supervision of Michael Lynch. Prior to that, she obtained a Master's in Biology from the Tata Institute of Fundamental Research in Mumbai, and a Bachelor of Science in Mathematics from Delhi, India.
Postdocs
Jacob earned his PhD at the University of Western Australia, Perth, advised by Dave Edwards where he focused on analyzing patterns of linkage disequilibrium in local regions of the genome. He is working on quantifying and modeling the linked effects of selection across the genome.

Graduate students
Austin earned his bachelor’s degree in Genetics from Texas A&M University in College Station, Texas, where he worked in Vaishali Katju’s laboratory studying the mutation rate and selfish genetic elements of C. elegans. He is co-advised by Dan Schrider in the Department of Genetics. In the Johri Lab, he is working on estimating the distribution of fitness effects of new non-coding mutations and transposable elements.

Alumni
Sachin Kaushik (July 2023 - Sep 2024) - Sachin earned his PhD at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bangalore, India, advised by Kavita Jain, where he developed theoretical models to explain genetic variation in a changing environment. As a postdoc in the Johri Lab, he developed a diffusion theory framework to model selective sweeps in non-recombining populations. He is now a Senior Data Scientist at Broadridge Financials in Bangalore, India. googlescholar
