- Molecular Pharmacology
The overarching goal of my research program is to investigate the structure, function, and regulation of G protein-coupled receptors (GPCRs), their interacting proteins, and their roles in neuropsychiatric disorders, including schizophrenia, depression, and substance use disorders. We also seek to understand how environmental factors and chronic drug exposure reshape behavior through molecular, cellular, and neural circuit mechanisms. Our research integrates a broad range of interdisciplinary approaches, including computational structural modeling, molecular pharmacology in cellular systems, neurochemistry, epigenetics, mouse behavioral assays relevant to psychiatric disorders, and functional analysis of postmortem human brain tissue samples. By combining these complementary approaches, we aim to elucidate the mechanisms by which GPCR signaling contributes to both normal brain function and disease pathology. Ultimately, our goal is to translate fundamental mechanistic discoveries into novel therapeutic strategies for the treatment and prevention of psychiatric disorders.
