My research encompasses discovering novel molecular drivers of melanoma, and using these discoveries to identify novel melanoma prevention and therapeutic strategies. My contributions in this area broadly include elucidating the role of inflammatory and metabolic signaling in cancer for prevention and therapy resistance. My research employs integrated analysis of high-throughput biological screens and functional genetics assessments. With these approaches, we hope to identify molecular features that promote melanoma and those which could be targeted for its treatment.
Solar ultraviolet radiation (UVR) is the predominant cause of cutaneous melanoma. My basic science research is directed towards identifying molecular mediators of melanoma driver mutagenesis induced by UVR exposure. Multiple events occur between UVR-mediated skin damage and oncogenic transformation of melanocytes. The goal of this research is to understand these events and develop melanoma prevention strategies post-UVR damage to the skin.
Targeted therapies and immunotherapies have meaningfully improved the survival time and quality of life of melanoma patients. However, resistance to these treatments is a significant problem, which eventually leads to disease progression and mortality. My translational research is directed towards identifying molecular and metabolic vulnerabilities in treatment-resistant melanomas, and targeting them to counteract therapy resistance.
