Hello! I am a tenured Associate Professor at Florida International University's Robert Stempel College of Public Health and Social Work in the Department of Health Promotion and Disease Prevention. I have over 15 years of experience in design, implementation and analysis of HIV/STI prevention, substance use, and health promotion projects with couples, primarily with sexual minority and gender minority adult populations (e.g., LGBTQ+) in the U.S. and abroad. 

My program of health disparity research with sexual and gender minority couples leverages digital health and relationship science to improve health outcomes by developing, testing, and evaluating couples-based prevention interventions. As PI or Co-PI, I have successfully led a variety of NIH-funded projects (e.g., R34s, R21s), and I am currently leading six funded projects (e.g., R01, R01, R34, R21, Admin Suppl.), including 3 randomized controlled trials and two cohort studies. My program of research: is theoretically guided by the Couples Interdependence Theory for Health Behavior Change; is web-based (Digital Health); applies mixed methods; collects qualitative, quantitative, biomedical, and para/intervention data from both partners of the relationship (i.e., dyadic data); focuses on couples. My content expertise and experience in conducting research with couples centers on behavioral and biomedical approaches to HIV/STI prevention, substance use, and relationship dynamics (e.g., communication, commitment, sexual agreements and guidelines, trust, communal coping, and transformation of motivation). In addition, I also conduct research on approaches to multiple health behavior changes with couples. 

In conjunction with research, I enjoy mentoring at all academic levels, from undergraduate and graduate students, postdoctoral research associates to junior faculty. Often, mentees are involved in any number of my ongoing projects to gain practical experiences and skills to apply to their own program of research and interests. Courses I have taught primarily focus on research methodologies, health behavior theory, and/or application of digital health to improve the public’s health.
