I am an Associate Professor of Public Health Sciences at the University of Rochester Medical Center. I completed my pre- and post-doctoral training in epidemiology, social, behavioral science, and global health. I have strong expertise in using complex data-driven and epidemiologic methods to assess research gaps, intervention opportunities, and the efficacy/effectiveness of existing interventions and health programs in various research contexts. Furthermore, I have an unparalleled passion for cultivating organic, diverse, inclusive, and sustainable environments across various settings through my professional services, research, and teaching.

I teach PM416: Advanced Epidemiologic Methods, PM451: Infectious Diseases Epidemiology, PM510: Causal Inference in Epidemiology, and I am directing PM460: Master of Epidemiology Thesis Workshop. I enjoy mentoring and working with students of various backgrounds and helping my students to become academically competent.

My research focuses on leveraging advanced quantitative/qualitative methods, social-behavioral theories, implementation science, and technology (e.g., social media) to design/implement novel prevention interventions to tackle a wide array of research priorities, such as social stigmatization among marginalized populations (e.g., LGBTQ populations), health messaging, substance use, mental health, social determinants of health, quality-of-life, and infectious disease prevention (e.g., HIV, STD, and COVID). I have served as the PI/Co-PI/Co-I of multiple institutional and NIH-funded studies and published frequently in reputable peer-reviewed journals. My research involves close collaboration with multidisciplinary teams in academia, medical/clinical institutions, community-based organizations, and government (e.g., CDC, Department of Health).
