About the Presenters:

Patrick Janulis, PhD, is an associate professor of medical social sciences at Northwestern University Feinberg School of Medicine and a quantitative methodologist for the Third Coast CFAR. His research examines the intersection of HIV, drug use, and LGBTQIA+ health. Janulis’ early work focused on using latent variable modeling to improve the measurement of HIV risk behavior and understanding within person variation in risk behavior across different environments and social circumstances. More recently, he has concentrated on leveraging modern data science approaches to measure, understand, and intervene on the root causes in the spread of HIV.

Benjamin Schalet, PhD, is an universitair docent in the Department of Epidemiology and Data Science at Amsterdam University Medical Centers. His research focuses on the methodology of developing and applying patient-reported outcomes (PROs) instruments, with an emphasis on psychometrics and standardized PRO assessments such as the Patient-Reported Outcomes Measurement Information System (PROMIS). Schalet is particularly interested in the psychometrics of “linking” different PRO instruments (scores) to each other, a procedure that is more broadly relevant to integrative data analysis. He conducts similar research in collaboration with the Department of Medical Social Sciences at Northwestern University Feinberg School of Medicine, where he was a faculty member for 10 years. Schalet’s current projects encompass a variety of focus areas, including patient engagement, depression, substance use, mindfulness, and olfaction.
