Research Interests

Dr. Goswami's laboratory is pursuing a mechanistic understanding of the role intracellular redox-state plays in regulating the mammalian cell cycle, and the application of these findings in aging and cancer research. His lab first reported the concept of a redox-cycle within the cell cycle linking cellular metabolism to cell cycle progression. His lab discovered a new mode of cellular aging, chronological lifespan which is defined as the duration during which normal human quiescent fibroblasts retained their capacity to re-enter the cell cycle. Recent research efforts focus on understanding mechanisms regulating metabolic reprogramming during aging of normal human fibroblasts and their effects on cancer progression and therapy response in a stromal environment.

Research efforts are also focused on understanding the cellular and molecular mechanisms regulating cancer cell growth-state specific response to therapy. These efforts are based on a clinical study where the clinicians observed that the survival of head and neck cancer patients is significantly worse in patients with lower pre-therapy tumor F-18 Fluorothymidine (FLT) uptake (SUVmax ≤ 5.5; p=0.04), suggesting that cancer cell growth-state contributes to therapy outcome. Ongoing efforts investigate whether cancer cell growth-state specific metabolism regulates therapy response.
