Bio

Karen E. Nelson, Ph.D. is the President of the J. Craig Venter Institute (JCVI). Prior to being appointed President, she held a number of other positions at the Institute, including Director of JCVI's Rockville Campus, and Director of Human Microbiology and Metagenomics in the Department of Human Genomic Medicine at JCVI. Dr. Nelson received her undergraduate degree from the University of the West Indies, and her Ph.D. from Cornell University. She has authored or co-authored over 170 peer reviewed publications, edited three books, and is currently Editor-in-Chief of the journal Microbial Ecology. She also serves on the Editorial Boards of BMC Genomics, GigaScience, and the Central European Journal of Biology. 

Dr. Nelson is an elected member of the National Academy of Sciences and serves on their Board of Life Sciences. Other honors include being named ARCS Scientist of the Year 2017; a Fellow of the American Academy of Microbiology; an Honorary Professor at the University of the West Indies; and a Helmholtz International Fellow.

Dr. Nelson has extensive experience in microbial ecology, microbial genomics, microbial physiology and metagenomics. Dr. Nelson has led several genomic and metagenomic efforts, and led the first human metagenomics study that was published in 2006. Additional ongoing studies in her group include metagenomic approaches to study the ecology of the gastrointestinal tract of humans and animals, studies on the relationship between the microbiome and various human and animal disease conditions, reference genome sequencing and analysis primarily for the human body, and other -omics studies.

Research Priorities

Microbiome in health and disease

  • Interrogating microbiome profiles and host microbe interactions

Emergence of Antimicrobial Resistance

  • Understanding the intricate play between infectious species, gene transfer and the emergence of resistance

Understanding Resistance mechanisms in microbial species

  • Deep investigations into how microbes respond to different types of drugs

Identification of novel species

  • In different environments including the oral cavity, plants, and artic sediments
