I am an Assistant Professor in the School of Medicine at UC Davis.
My current work, funded by a NIDA K99/R00, is developing methods to transport mediation effects from one population to another and apply them to understand how school characteristics mediate relationships between neighborhood factors and adolescent drug use.
My research interests are in applying causal inference methods to studying social and contextual influences on mental health and substance use in disadvantaged, urban areas of the United States. My thesis work examined effect heterogeneity in the association between living in a disadvantaged neighborhood and adolescent anxiety and depression. I was advised by Tom Glass and Liz Stuart .
I'm currently working with:
- Mark van der Laan in developing targeted minimum loss-based estimators for transporting encouragement design interventions across sites estimating mediation effects, with
- Jen Ahern and Maria Glymour applying these estimators to understanding site variability in policy and program effects, and with
- Magdalena Cerdá understanding the health effects of substance use policies and the risk landscape of the opioid epidemic.
Previously, I've worked closely with Michael Rosenblum and Ivàn Dìaz on evaluating simple estimators of an average treatment effect in the presence of effect heterogeneity, a double selection mechanism, and treatment bias; Kathleen Merikangas during my predoctoral fellowship at NIMH; and with Justin Lessler, Derek Cummings, and the Johns Hopkins ID dynamics group on estimating the incubation periods of various infectious diseases.
Prior to academia, I worked at Altarum Institute in Washington, DC, evaluating and providing technical assistance to local, state, and federal maternal and child health programs, such as WIC, SNAP, and other early childhood initiatives. I also supported viral vaccine manufacturing at Merck. I received an MPH from Johns Hopkins in 2008 and a BS in biochemistry from the University of Michigan in 2005.
