I'm a PhD candidate in clinical psychology at Northwestern University. Broadly, I am interested in how we classify and diagnose mental health problems in children and adolescents. I use disorder co-occurrence, also called comorbidity, to understand transdiagnostic features of mental illness. Much of my research also investigates how psychological symptoms overlap with normative personality traits.

I also maintain a complementary line of work on methods for increasing transparency and replicability in scientific research. Specifically, I am interested in how "open science" methods can be made accessible and inclusive to a wider variety of researchers.
