Speaking & Workshops

Dr. Dorfman speaks on the intersection of brain health and mental health, translating neuroscience and psychology into practical insights for everyday life and work. Her talks explore how the brain shapes the way we think, feel, perform, and respond to stress—and how evidence-informed strategies can support cognitive and emotional well-being.

The High-Performance Paradox

Columbia Business School

An exploration of the neuroscience and psychology of high performance, including how the same traits that fuel achievement can contribute to stress and burnout. The discussion examined the effects of sustained pressure on the brain and strategies for protecting cognitive and emotional well-being while pursuing ambitious goals.

Women’s Mental Health

Tishman Speyer

A conversation about the unique pressures affecting women’s mental health, from cognitive and emotional load to competing professional and personal demands. The discussion explored stress, burnout, boundaries, and practical ways to support resilience and well-being across different stages of life.

The Brain’s Chemical Messengers

L’Occitane

An accessible introduction to neurotransmitters and the ways brain chemistry influences mood, motivation, stress, sleep, and well-being. The discussion explored key neurotransmitter systems—including dopamine and serotonin—and everyday behaviors that support healthy brain function.
