Jan Geliebter, Ph.D., has had an interest in science at the age of eight when his parents bought him a chemistry set. Following postdoctoral training in the molecular genetics of the Major Histocompatibility Complex with Dr. Stanley Nathenson at the Albert Einstein College of Medicine, Dr. Geliebter's career has focused on the molecular pathogenesis and immunology of cancer, as well as immunological diseases.

Over the last 19 years, with the help of supportive chairs, supportive faculty and graduate students, Dr. Geliebter has been the director of the medical microbiology course for second-year medical students. During this time, he has maintained an active research laboratory and mentored residents, graduate students, medical students, M.D.-Ph.D. students, undergraduate students, and high school students.

Research

Dr. Geliebter's laboratory uses RNASeq to interrogate the landscape of gene expression alteration in PTC in clinical samples. By comparing PTC and samples of normal tissues from the same patients, the researchers have gained insight into the molecular changes driving PTC, as well as potential therapeutic targets. As men have a lower incidence of PTC than women, the lab is concentrating on the role of androgens in the etiology and progression of PTC. The results indicate that androgens exert an anti-proliferative effect and result in a G1-S block in the cancer cell cycle.
