Staff Scientist

Dr. Tarnecki (formerly Larsen) investigates the relationship between host-associated bacterial communities (microbiota) and host health. Her current research projects include: isolation and testing of beneficial bacteria, or probiotics, to improve aquaculture production of finfish; examining indirect effects of environmental stressors such as oil exposure and harmful algal blooms on vertebrate health via their manipulation of the host microbiota; and identification of antimicrobials produced by bacteria isolated from marine environments that are effective against antibiotic-resistant human pathogens
