I am currently Associate Professor in and Director of the Health Policy Program at the University of the Sciences in Philadelphia. I also have an appointment as a Researcher at the National Center for Homelessness Among Veterans at the US Department of Veterans Affairs.

My research has focused on homelessness and housing. From here, my work has extended to institutions that intersect with homelessness, such as the military, jails and prisons, and child welfare. Additionally, I've researched health issues that are prevalent among homeless populations such as mental illness and HIV/AIDS. My research has appeared in a wide range of peer-reviewed publications, including JAMA, the American Journal of Public Health, and Social Service Review.

I have consulted for public and non-profit organizations, mostly with assisting them in using their administrative data to more effectively and efficiently provide services.

My teaching covers a variety of sociology and policy courses, mostly on the graduate level, and I have advised and mentored numerous students on PhD dissertations and other research. I have also worked with Temple University's Inside Out program in teaching criminal justice courses in Philadelphia jails.

I have a PhD in Sociology from the University of Pennsylvania, an MA in Urban Studies from the University of Texas at Arlington. Prior to coming to Philadelphia, I did casework and advocacy around homelessness in San Antonio and Fort Worth, Texas.
