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 establishment of a link between reactive oxygen species (ROS)-signaling and other aspects of intracellular signaling network during normal cell aging and cancer cell therapy response.

Research efforts are focused on understanding the possible role of mitochondria generated ROS-signaling pathways regulating (a) normal fibroblast aging; (b) fibroblast aging on cancer cell proliferation and therapy response; and (c) cancer cell quiescence and radiation therapy response. Molecular and pharmaceutical methods are used to determine a mechanistic role of antioxidant and cell cycle genes regulating fibroblast aging and cancer cell therapy response.

Additional research efforts include investigating the role of oxidative stress regulating cellular response to polychlorinated biphenyl (environmental pollutant) and antioxidants mitigating these adverse effects.

The knowledge gained from these research projects may provide novel insights into the redox-regulation of the mammalian cell cycle both in physiological as well as pathological states. This knowledge may allow us to develop antioxidant-based preventive and therapy protocols to promote healthy-aging and delay the onset of age-associated proliferative diseases.
