Katherine Andrinopoulos's research focuses on uptake of HIV testing and adherence to the HIV care continuum for key populations. She recently developed global guidance for conceptualizing and measuring quality of HIV services for MSM and Transgender Women. She is currently developing a guidance document and online training to support the incorporation of sexual orientation and gender identity questions in data collection. She also leads a project on gender-related barriers to the HIV care continuum for key populations in Vietnam and the Dominican Republic.

Dr. Jeanette Gustat's primary research interest is in the assessment of how behavior and the physical environment impacts health outcomes.

Dr. Engel's research focuses on the impact of mobile element activity on human health, in particular the human transposable elements (TEs), L1, and alu elements. Her main goal is to investigate the mechanism by which transposable elements contribute to disease and how environmental factors, such as heavy metal exposure, contribute to TE-mediated genomic instability and disease. Dr. Engel uses ex-vivo studies and the state-of-the-art whole-genome next-generation sequencing (NGS) approaches to investigate the contribution of mobile elements to human diseases such as cancer.  Dr.
