Research Summary

I am a physician-scientist experienced in clinical and translational laboratory efforts to understand and improve upon cancer immunotherapies.

Clinically, I see patients in the Cancer Immunotherapy Program where I am an attending physician, principal investigator, and co-investigator on early-phase/first-in-human trials testing novel immunotherapies in advanced solid tumors, with a particular focus on genitourinary malignancies. This includes high-risk modalities such as bispecific T cell engaging therapies, immune agonist antibodies, intratumoral immunotherapy, and adoptive cell therapies.

In the laboratory, I study samples from prostate and bladder cancer patients treated with immunotherapy using unbiased platforms such as single-cell RNA sequencing and T cell receptor sequencing. The goal of this work is to discover and validate novel T cell populations and antigenic specificities that are responsible for anti-tumor efficacy as well as immune-related adverse events (IRAEs) resulting from treatment.
