Curriculum Vitae:

Melissa Caimano received a B.S. degree from the University of Rhode Island in 1989. She attended graduate school at the University of Alabama at Birmingham doing her thesis work on the genetic elements involved in Streptococcus pneumoniae capsule biosynthesis. In 1996, Caimano began a post-doctoral fellowship with Dr. Justin Radolf at the University of Texas Southwestern Medical Center in Dallas, relocating to the University of Connecticut in 1999. Her work has focused primarily on the regulatory pathways and molecular mechanisms underlying mammalian host adaptation and maintenance of Borrelia burgdorferi within its natural enzootic cycle. Most notably, these studies have led to the discovery that the alternate sigma factor RpoS plays a critical role in the down-regulation, as well as up-regulation, of borrelial genes specifically in response to mammalian host signals. She has published more than 46 peer-reviewed articles on microbial pathogenesis and related areas in high impact journals. Her work examining the interaction between the Lyme disease spirochete and its arthropod vector is supported by grants awarded to her by the National Research Fund for Tick-Borne Diseases (NRFTD) and the National Institutes of Health (NIH/NIAID). Caimano currently is an Assistant Professor in the UConn Health Department of Medicine and holds a secondary appointments in the Departments of Pediatrics and Molecular Biology and Biophysics. She has served on the Editorial Board of Infection and Immunity since 2006 and PLoS Neglected Tropical Diseases since 2015.

Her work has focused primarily on the regulatory pathways and molecular mechanisms underlying mammalian host adaptation and maintenance of Borrelia burgdorferi within its natural enzootic cycle. Most notably, these studies have led to the discovery that the alternate sigma factor RpoS plays a critical role in the down-regulation, as well as up-regulation, of borrelial genes specifically in response to mammalian host signals. More recently, Dr. Caimano has identified a central role for the small nucleotide second messenger, c-di-GMP, for maintenance of B. burgdorferi in its arthropod vector. She has published more than 60 peer-reviewed articles on microbial pathogenesis and related areas in high impact journals
