Welcome to the Curtis Lab

The Curtis Lab pairs traditional methodologies with computational psychiatry to study the digital phenotypes of people who use drugs. While much of the labs focus is on converting raw signals from digital data sources into useful clinical insights, the TTRU is very much committed to solving problems experienced by people in recovery and undergoing substance use treatment. Through clinical research, the Curtis lab intersects addiction treatment, computational psychiatry, and innovative technologies. Using natural-language processing, digital phenotyping, and deep learning, the lab focuses on enhancing precision assessment of substance use and behavioral predictors using intensive longitudinal data and integrating passive sensor data from smartphones and wearable devices. Among others, an overall goal is to develop personalized smartphone interventions for individuals living with SUD to enhance the recovery experience. Other areas of research focus on the intersect between addiction and Covid and on the impact of stigma on addiction.

We are looking for passionate new PhD students, Postdocs, and Master students to join the team (more info) !
