Alex Harris, Ph.D.

Department of Genetics,
University of Pennsylvania


2014 B.S. Genetics, Cell, and Developmental Biology; Biochemistry—Arizona State University, Tempe, AZ

2020 Ph.D. Molecular, Cellular, and Integrative Biosciences—The Pennsylvania State University, University Park, PA

2020-Present PennPORT fellow, Department of Genetics—University of Pennsylvania School of Medicine, Philadelphia PA

Research Mentor: Sarah Tishkoff, Ph.D.
Research Topic: I am interested in characterizing the microbiomes of diverse African populations. Understanding the microbiome is key to understanding the health of any population, and I am particularly interested in approaching this topic from a metabolic perspective. To do this, I am studying the interaction between host metabolic traits, host genome, and microbiome functions, using various approaches. My hope is to translate this work toward health interventions in global populations with African ancestry.

Teaching Interests: Introductory Biology, Introductory Biochemistry, Population Genetics
