Director, Principal Investigator
Professor-in-Residence in the Department of Psychiatry and Biobehavioral Sciences, and Director of the Eating Disorders and Body Dysmorphic Disorder Research Program, and the Adult Obsessive-Compulsive Disorder Program. He is currently funded by the NIH to study visual and emotional information processing in BDD and anorexia nervosa, as well as anxiety and reward processing in anorexia nervosa. His research seeks to understand phenotypes of perceptual and emotional processing that cross diagnostic boundaries of conditions involving body image such as BDD, eating disorders, and gender dysphoria. He also studies neurometabolites and brain connectivity in individuals with OCD, and how they are affected by cognitive-behavioral therapy.
Teena’s research is focused on techniques to analyze data from different sources including functional MRI, DTI, resting state data, and neuropsychological assessments to investigate the neural bases of several disorders. She is excited about exploiting multiple modalities to discover how pharmacological and behavioral treatments affect brain function, with a long-term goal of helping to develop early detection techniques and intervention therapies for disorders such as BDD, Anorexia Nervosa, ADHD, and OCD. Prior to receiving her Ph.D in Neuroscience at UCLA, Teena worked at Hughes Aircraft Company and Sirius II Corp, on projects varying from laser-eye-protection goggles and infrared imaging systems, to projection systems for 3-D movies. She has a very understanding husband, two wonderful kids, and a crazy dog.
Courtney Sheen, M.A. is a staff research associate in the Department of Psychiatry and Biobehavioral Sciences. She earned her bachelor’s degree in psychology and linguistics from California State University, Northridge and her Master’s from Pepperdine University. A great deal of her work is in the administration of psychological assessments.
Dr. Reza Tadayon-Nejad, MD, PhD, is an assistant clinical professor of psychiatry at UCLA. He earned his medical degree from Ahwaz University of Medical Sciences and a PhD in Neuroscience from Hotchkiss Brain Institute, University of Calgary, Canada. He then completed a residency in psychiatry at University of Illinois at Chicago (UIC) followed by a NIMH T32 fellowship in Neuroscience of Mental Health with focus of psychiatric neuroimaging before coming to UCLA. His research focus during residency and fellowship was on structural and functional large scale brain networks dysfunction in depression and anxiety disorders by using resting-state functional magnetic resonance imaging (fMRI), diffusion tensor imaging (DTI) and EEG methods. He applied different computational approaches including functional connectivity, Granger analysis based effective (directed) connectivity, spectral analysis and graph theory based Connectomics for brain networks analysis research. In his current project in the lab, he uses a multimodal imaging approach integrating magnetic resonance spectroscopy (MRS) and fMRI methods to study biochemical and functional mechanisms of brain network dysfunction in subjects with Obsessive-Compulsive Disorder (OCD).
Joel Diaz is a research associate in the Department of Psychiatry and Biobehavioral Sciences. He graduated from Florida State University with a BS in Psychology, Minors in Biological Science and Social Welfare, and certification in SAS Programming and Data Analysis. He has a broad range of research interests, but his focus is on the use of psychophysiological methods and neuromodulation techniques in the study and treatment of psychological and neurological disorders.
Emmily Hovhannisyan is a research associate working with Dr. Feusner and Dr. Tadayon-Nejad. She graduated from UCLA with a BA in psychology and is interested in depression (specifically anhedonia), OCD, and anxiety. As a member of the lab, she primarily investigates appetitive conditioning in anorexia nervosa and decision-making in OCD. Outside of work, Emmily enjoys reading, watching movies, and spending time outdoors.
Natalie Rotstein graduated from UCLA with a BS in neuroscience. She is currently a research associate in Dr. Feusner’s lab, primarily working on neuroimaging, data analysis, and neurocognitive testing. Her main research interest is to improve our understanding of the neurological bases of psychiatric illnesses and, in turn, develop more effective interventions. In her free time, Natalie enjoys fostering dogs.
DS Adnan Majid, MD, PhD, is a psychiatry resident at the UCLA Semel Institute for Neuroscience and Human Behavior. After completing undergraduate studies in Symbolic Systems at Stanford University, he completed medical training at the University of California, San Diego, where he also studied cognitive neuroscience. He obtained his PhD with Dr Adam Aron, PhD, studying the neural pathways of action control using structural and functional MRI and transcranial magnetic stimulation.
