About Us

Principal Investigator

Dr. Leanne Williams


Associate Chair for Research Strategy and Oversight
Stanford University School of Medicine, Psychiatry and Behavioral Sciences

Director, PTSD Education
VA Palo Alto Sierra-Pacific MIRECC

Over the past 13 years my research program has been motivated by the need for a new model of mental disorder, one that integrates two complex systems: human brain function and human behavior. 

In 2013 I commenced my faculty position as Professor of Psychiatry and Behavioral Sciences at Stanford University. I also hold a position at the VA Palo Alto MIRECC, and have the leadership role of Director of PTSD Education. Prior to this, I was the Director of the Brain Dynamics Center for 12 years (2001 to 2013) and on faculty at the University of Sydney. In Sydney I was first a member of the tenured faculty in Psychology (1999-2004) and, subsequently, the Sydney Medical School, where I became foundation Professor of Cognitive Psychiatry in 2007, and where I continue to hold an active, honorary position. My PhD was awarded in 1996, and it was completed with a British Council scholarship for study at Oxford University.

My lab - the PanLab - was launched with an R01 project, funded under the NIMH "RDoC" initiative to develop a new understanding of mental disorder based on neurobiology. With this project as the foundation, we are forming at Stanford an interdisciplinary collaboration to advance personalized neuroscience for mental disorder.

PanLab Faculty

Andrea Goldstein-Piekarski, PhD

Instructor, Psychiatry and Behavioral Sciences

Andrea earned her PhD in psychology/neuroscience in 2014 from UC Berkeley. There she examined the impact of sleep loss on emotional brain function using high density EEG sleep recording, advanced MRI methods and emotion reactivity paradigms.

Her current research in the PANLab focuses on: (1) using big data methodologies to develop a data-driven taxonomy of depression and anxiety from multiple neurobiological measures of brain function, physiology, and behavior; (2) characterizing how physiological stress contributes to amygdala-anterior cingulate-medial prefrontal dysfunctions in anxiety and depression; (3) identifying objective biomarkers that predict general and medication-specific responses to antidepressant treatment. Andrea was awarded a post-doctoral NRSA fellowship to continue this research. Looking towards the future, Andrea aims to build a program of translational clinical research that utilizes advanced computational modeling, big data principles, human neuroimaging techniques and sleep physiology to develop a precision medicine approach for the treatment of psychiatric disorders.

PanLab Postdocs

Tali Manber Ball, PhD

Postdoctoral Fellow

Tali is a T32-funded postdoctoral fellow under the mentorship of Dr. Williams.  Her primary research aim is to translate neuroscience models of anxiety into improved treatment outcomes.  She received her PhD in Clinical Psychology from the University of California San Diego in 2015 under the mentorship of Drs. Murray Stein and Martin Paulus.  Her dissertation established relationships between brain activation during fear extinction learning and anxiety reduction following a brief exposure intervention.  Within the PanLab, her areas of research include (1) developing clinically useful metrics of brain circuit function (using data from iSPOT-DTWIN-E, and RAD), (2) incorporating neuroscience-based assessments into clinical practice (Precision Psychiatry Continuity Clinic), and (3) evaluating an online CBT intervention for transdiagnostic anxiety and depression symptoms (RADCAT).  She is also a therapist in Stanford’s Psychosocial Treatment Clinic, specializing in CBT and ACT for anxiety and depression.  Outside of work she enjoys dancing and bad puns.
