Publications

I believe that research and clinical work should inform each other. I am careful to never lose sight of the research, while also personalizing care for you. I was previously faculty at Stanford, researching brain development and its relationship with executive function, suicidal thinking, anxiety, and depression. Here are my peer-reviewed publications:
