Dr. Katherine Maki is an Assistant Clinical Investigator in the TBHD at the NIH CC and the head of the Biobehavioral and Integrated metagenOMics (BIOM) Unit.


The BIOM Unit designs, plans, and conducts research integrating biological, physiological, behavioral, psychological, and environmental factors to a) understand and synthesize microbe-brain signaling mechanisms connecting the oral and gut microbiome to health and disease b) combine multi-omic methodologies with in vivo and in vitro tools c) model disease-specific research protocols that identify shared and unique biomarkers and novel therapeutic targets.

Dr. Maki received her Bachelor of Science in Nursing from Marquette University in May of 2009, and her Master of Science in Nursing in May of 2015 from the University of Illinois at Chicago with a focus as an Adult-Gerontology Primary Care Nurse Practitioner. Dr. Maki was a pre-doctoral research fellow in the Laboratory of Sleep Neurobiology at the University of Illinois at Chicago Nursing Department, and she completed her PhD from the University of Illinois at Chicago in December of 2019.

Dr. Maki was an intramural postdoctoral research fellow in the Translational Biobehavioral and Health Disparities Branch from 2020-2022. In 2020 she was the winner of the American Heart Association Martha Hill Early Career Investigator Award, and she received the Outstanding Thesis/Dissertation Award from the University of Illinois at Chicago Graduate College, Life Sciences division.
