Abigail JS Armstrong, PhD

Postdoctoral Fellow


B.S. Biology, Calvin University, 2014
Ph.D. Microbiology, University of Colorado, Anschutz Medical Campus, 2020


Abigail Armstrong is a postdoctoral fellow in the lab of Dr. Martin Blaser studying the role of the human microbiome on health. Abigail received a PhD in microbiology from the University of Colorado Anschutz Medical Campus performing her dissertation work on the role of the gut microbiome in people living with HIV in the lab of Dr. Catherine Lozupone and a BS in Biology from Calvin University performing her thesis work creating computation methods for microbial community mass spectrometry in the lab of Dr. John Wertz. Abigail’s work is focused utilizing existing and creating new computational tools to better understand the human microbiome with the larger system of the human body. She is passionate about communicating scientific findings and resources both between conventional bench scientists and computational scientists and to the general public.
