Research Interests

My research focuses on determining molecular mechanisms involved in the regulation of gene expression and signal transduction pathways in cancer development and drug resistance by using high throughput sequencing technologies and cancer mouse models. I have recently identified CDK4/6 as a target for therapeutic intervention in melanoma. Therefore, I have utilized a CDK4/6 inhibitor (CDK4/6i) to suppress melanoma growth. Palbociclib is an FDA-approved CDK4/6i that has received a Breakthrough Therapy Designation and has emerged as a powerful anti-cancer therapy. It is currently being evaluated in clinical trials for many types of cancers such as melanoma, breast cancer, and glioblastoma. I am currently working on dissecting the molecular mechanisms of both intrinsic and acquired resistance to CDK4/6i in order to improve CDK4/6i based therapies and to overcome its resistance. My long-term goals are (1) to discover novel cancer therapeutics by identifying molecules and pathways that are critical for cancer development and drug resistance and (2) to improve cancer treatments by identifying druggable targets.
