Radolf and Caimano Laboratory
Justin Radolf, M.D., Professor of Medicine, Genetics and Developmental Biology, and Pediatrics
Justin Radolf received his B.S. degree in biology from Yale University in 1975. He attended medical school at the University of California, San Francisco, graduating in 1979. He was a resident in internal medicine at the Hospital of the University of Pennsylvania from 1979 to 1982. As a fellow in infectious diseases at UCLA (1982-1986), he began his research career in spirochetology, specifically studying Treponema pallidum, the cause of syphilis, a sexually transmitted disease. His efforts to use recombinant DNA to identify outer membrane proteins of T. pallidum led to the discovery of the unique protein-deficient outer membrane of T. pallidum. Following fellowship, he continued his spirochete research as a faculty member at the University of Texas Southwestern Medical Center. In the late 1980s, as Lyme disease began to emerge as an important public health problem, Radolf expanded his research program to include Borrelia burgdorferi, the cause of Lyme disease, the most prevalent arthropod-borne pathogen in the United States. In 1999, he relocated to UConn Health where he is currently professor of medicine, pediatrics, and genetics and developmental biology. He is an author or co-author on more than 150 peer-reviewed publications and more than 30 chapters or review. His spirochete research has been continuously funded by the NIH since 1988.
Melissa Caimano, Ph.D., Assistant Professor, Medicine
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 postdoctoral 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. She also has served on the Editorial Board of Infection and Immunity since 2006.
Ashley Groshong, Ph.D., Postdoctoral Fellow
Ashley Groshong received a B.S. in Biology and a B.A. in Chemistry and English from the University of Arkansas at Little Rock in 2009. She attended graduate school at the University of Arkansas for Medical Sciences completing her dissertation work on Borrelia burgorferi pathogenesis in the mammalian system and genetic manipulation related to the RpoS regulatory pathway in the laboratory of Dr. Jon Blevins. In 2014, Groshong obtained her Ph.D. and joined Dr. Justin Radolf’s laboratory at the University of Connecticut as a postdoctoral fellow to continue her evaluation of specific genes within the RpoS regulatory pathway and their impact on the enzootic cycle.
Sanjiv Kumar, Ph.D., Postdoctoral Fellow
Sanjiv Kumar received his Bachelor’s Degree in Veterinary Sciences and Animal Husbandry (B.V.Sc. & A.H.) in 2003 from the Veterinary College, Bangalore, India. He received his Masters’ Degree (M.V.Sc.) in Veterinary Microbiology in 2007 from Lala Lajpat Rai University of Veterinary & Animal Sciences (LUVAS), Hisar, India. He then moved to CSIR-Institute of Genomics and Integrative Biology, Delhi, India, for Ph.D. training (2009-2013) in Biotechnology. His doctoral dissertation involved the identification and characterization of potential adhesins of Mycobacterium tuberculosis. After receiving his Ph.D. in 2013, he joined the Metagenomics and Systems Biology Group at IISER Bhopal as a postdoctoral fellow. He enjoys reading, blogging, and table tennis and learns shell scripting in his free time.
