Itzhak Fried, M.D., Ph.D.

Dr. Fried is Professor of Neurosurgery and Psychiatry & Biobehavioral Sciences at UCLA.  He is Director of the Adult Epilepsy Surgery Program there, and is also Co-Director of the Seizure Disorder Center.  Concurrently, he is a Professor of Neurosurgery at Tel-Aviv University in Israel.  After obtaining a degree in physics at Tel-Aviv University, Dr. Fried completed his Ph.D. at UCLA, and went on to a medical degree at Stanford and neurosurgery training, specializing in epilepsy surgery, at Yale University.  He heads the Cognitive Neurophysiology Laboratory, which is centered on the opportunities to study the human brain afforded by the epilepsy surgery program at UCLA.  A small number of these patients have depth electrodes inserted in order to evaluate their seizures for subsequent surgery.  It is this opportunity that is used

Emily Mankin, Ph.D

Emily Mankin, PhD, is a project scientist whose interests lie in understanding the neural mechanisms of memory formation and consolidation, as well as developing methods for enhancing these processes. Specifically, she uses both non-invasive (auditory cues) and invasive (deep brain stimulation) methods to encourage encoding, consolidation, and retrieval during memory tasks and sleep. She is interested in both the basic science implications of these manipulations (what do they tell us about how the brain “does” memory?) and their potential for therapeutic use for the growing number of people who are impacted by memory disorders. Before joining the Cognitive Neurophysiology Lab as a postdoc, she worked as a teacher and a mathematician, and completed her PhD in Computational Neuroscience at UCSD under the mentorship of Drs. Stefan and Jill Leutgeb. Her

John J. Sakon, Ph.D

John Sakon is a project scientist that oversees lab recruitment, research projects, and contributes to scientific goals. He has a BS in physics from William & Mary, a PhD in physics from NC State, and did postdoctoral training with Wendy Suzuki and Roozbeh Kiani at NYU and Michael Kahana at UPenn. John’s research interests include understanding the neurophysiological basis of memory and translating these findings to ameliorate memory dysfunction in humans. When not studying memory he plays ultimate and drinks fancy tea. He does one of those while studying memory too. To learn more about John’s research click “LEARN MORE” below:

Soraya Dunn, Ph.D

Soraya Dunn, PhD. is a Postdoctoral Scholar who is interested in the neural mechanisms of memory, particularly memory consolidation during sleep. She completed her graduate training at University College London co-supervised by Prof. Jenny Bizley (UCL Ear Institute) & Prof. Daniel Bendor (UCL Institute Behavioural Neuroscience) where she investigated the hippocampus – a region critical for memory- through novel cross-species comparisons. Her current projects include decoding brain-wide activity patterns during sleep to develop a deep brain stimulation paradigm for the enhancement of specific memories. Outside of the lab she likes to go hiking, but really slowly so she can look at all the birds and mushrooms and trees, and anything else that catches her eye.

Chris Chan

Chris is a Clinical Specialist in Dr. Fried’s group. He facilitates functional neurosurgical cases at Ronald Reagan Medical Center and fabricates research microelectrodes. Chris holds a triple major in neuroscience & cognitive science, biochemistry, and molecular & cellular biology from the University of Arizona. His senior thesis on transcranial ultrasound and its effect on Alzheimer’s is what drew him to the field of brain stimulation and memory. Chris previously researched the cardiac autonomic system in the porcine model at the David Geffen School of Medicine, where he has also collaborated with Amgen in a pharmacological study for anti-arrhythmia drugs. He hopes to create a lasting impact in electrode design in Dr. Fried’s group. In his free time, he cooks and plays MMOs.
