Cara Woodworth, B.A. 

Assistant Clinical Research Coordinator; [email protected]

Lead Project: Multimodal MRI Characteristics of Psychotherapy Response in Late Life Depression. (Psychotherapy Response Study)

Cara Woodworth graduated with a Bachelors degree in psychology from the University of California, Berkeley, where she realized her love for research. Coming from a lab which focused on improving cognitive behavioral therapy, she is very excited to be the coordinator for the Psychotherapy Response study since it focuses on the neurological outcomes of therapy. She is particularly interested in how the neurology of mental illness can help us better understand the connection between disordered sleep and psychopathology, and she intends to pursue a Ph.D. to continue researching these topics. When not working, she can be found writing urban fantasy or exploring the Oakland food scene.
