Biography

At Roswell Park Comprehensive Cancer Center, my clinical practice and research is focused on immunodeficiency-associated skin cancers and skin disorders associated with solid organ transplantation. My research has centered on defining the role of immune cells called macrophages in tumor progression. The focus of these studies has been to identify pathways of tumorigenesis critical to a variety of murine tumor types including lung carcinoma, melanoma, colon carcinoma and cutaneous squamous cell carcinoma. Parallel studies in identifying tumor-promoting pathways induced by infiltrating macrophages in human cutaneous squamous cell carcinomas from immunosuppressed versus non-immunosuppressed patients is the current focus of our lab.

I am a member of several professional organizations related to my clinical and research interests. Specifically, I am the president-elect of the International Transplant Skin Cancer Collaborative, the largest international organization dedicated to studying and treating skin diseases that develop after solid organ transplantation. Further, I am also a member of the American Academy of Dermatology, Society for Investigative Dermatology and American Dermatologic Association.

As a native Texan, I graduated from The University of Texas, where I earned a BS in Pharmacy in 1995, and of Yale University where I earned a PhD in Cell Biology in 2003 and an MD, with election to Alpha Omega Alpha medical honor society, in 2004. I completed an Internship in Internal Medicine and a Residency in Dermatology at Yale-New Haven Hospital. In 2015, I was honored to receive the Young Physician-Scientist Award of the American Society for Clinical Investigation and the 2017 Young Investigator Award of the American Academy of Dermatology.
