About
I am an Assistant Professor of Clinical Psychiatry at Columbia University, where I direct research on ADHD, cannabis use disorders, and digital mental health interventions. My work combines large-scale data science with clinical expertise to improve psychiatric care.
A unique perspective: I've been online since 1994—26 years of watching technology evolve. This gives me a long-term view on digital health that informs my research and clinical approach.

COVID-19 & Telehealth
The pandemic has accelerated the digital mental health transformation I've been anticipating since 1994. Telehealth has gone from niche to mainstream overnight:
- Conducted 500+ telepsychiatry sessions in 2020
- Studying effectiveness of virtual ADHD care
- Developing best practices for remote psychiatric assessment
- Training residents in telepsychiatry skills
This moment validates decades of belief that technology can democratize mental healthcare access.
