Cancer Research Interest
- Disease Site Focus: No Specific Disease Site, Multiple Myeloma, Breast, Gynecology, Hematologic Malignancies, Leukemia/ Lymphoma
- Research Focus Area: Carcinogenesis, Treatment, Informatics
- Type of Research: Basic, Translational
- Research Keywords: Programmed cell death; apoptosis; necroptosis; ferroptosis; structural and chemical biology; membrane and signaling proteins
- Research Interest Statement: Programmed cell death plays a central role in normal biology and cancer pathogenesis. Our laboratory uses structural and chemical biology to explore the mechanisms underlying cell death. We are interested in identifying and understanding how programmed cell death pathways can be targeted as a therapeutic approach. The mechanisms that manipulate programmed cell death play critical roles in regulating homeostasis but are often deregulated in cancer, which leads to chemotherapy resistance. Our research encompasses elucidation of the regulatory mechanisms responsible for apoptosis initiation as well as necroptosis and ferroptosis execution, all of which involve membrane permeabilization events. Additionally, we are designing small molecule chemical probes for key targets in these pathways for use in preclinical cancer research broadly applicable to many types of cancer.
