About Me

I chose to pursue medicine because I wanted a career in which I could directly and tangibly help people. The field of oncology was rapidly advancing while I was in medical school, and we were gaining a better understanding of how cancer develops at the molecular level and how we could intervene. As a medical oncologist, I find it so rewarding to help my patients by identifying the problem and implementing a comprehensive treatment plan.

At Perlmutter Cancer Center, I recommend and create treatment plans primarily for people who have gastrointestinal cancers, with a particular focus on pancreatic cancer. I coordinate their treatment by collaborating with multiple specialists, including surgical and radiation oncologists and pathologists.

Every person is unique and has unique needs, so I take a personalized approach to care. I want to understand people’s goals of care and their individual priorities. I’m concerned with how far they’re traveling to receive care and who will accompany them, so I can factor these variables, among many others, into their treatment. Cancer care is a combination of science and compassion, and I aim to provide both for my patients.

I also run clinical trials that I design and develop with my colleagues. Currently, I am studying immunotherapy for pancreatic cancer, including how to improve treatments and how the microbiome interacts with pancreatic cancer. Our goal is to develop effective treatments for gastrointestinal cancers at every stage. If there isn’t a cure or if current treatments have unpleasant side effects, then we can work toward creating better care.

I am the institutional principal investigator for the ECOG-ACRIN Cancer Research Group, which is a national cooperative oncology group that conducts clinical trials that are funded by the National Cancer Institute. Additionally, I am a member of the American Society of Clinical Oncology.
