Biomedical Research Assistant Volunteer

A highly motivated Biomedical Engineer, Huy’s academy research project is in Traumatic Brain Injury (TBI) focus on the force-sensitive resistor (FSR) application in a helmet to monitor head trauma and reduce TBI. His past research at the University of California, Davis, applied the groundbreaking gene-editing method CRISPR/Cas 9 to gene-edit Arabidopsis’s antiporter DNA. Since 2011, Huy has served in the US Army Medical Service Corps. From 2018-2019, Huy directs a multi-profession team to provide health/medical training for thousands of U.S military personnel and local nationals in Central America. In community service, since 2016, Huy is the Event General Director for Miss Vietnam North California and the Director for the Golden Heart Charity Organization since 2012.


Sohrab Sami

Research Assistant Volunteer

I completed my B.S in psychology with a clinical concentration. My goal is to get my PhD in clinical psychology and study neuroplasticity of the brain and its role in the therapy setting and rehabilitation. I am currently coordinating a study that aims to understand the neurological and neuropsychological effects of mild TBI in collegiate athletes.

Neuropsychological Assessor 

Ryan is an Adjunct Professor and a PhD Candidate in Clinical Psychology at Palo Alto University. He aims to become a board-certified clinical neuropsychologist and researcher specializing in traumatic brain injury across the lifespan. Ryan began working with Dr. Adamson in 2017 through the Defense and Veterans Brain Injury Center at the VA Palo Alto Health Care System. In 2020, he co-authored a manuscript on sex differences in symptom presentation and functional outcomes following mild traumatic brain injury with Dr. Adamson. Currently, Ryan is the lead neuropsychological assessor on a project looking to determine the efficacy of repetitive transcranial magnetic stimulation in treating symptoms of mild traumatic brain injury. In addition to his work with the Adamson Brain Stimulation Lab, Ryan is a doctoral research assistant in the Department of Psychology at the VA Palo Alto Health Care System and a neuropsychology practicum student at the UCSF Memory and Aging Center and Stanford Cognitive Systems and Neuroscience Lab.

Principal Investigator

Dr. Maheen Mausoof Adamson is Clinical Research Senior Scientific Director for Headache Center of Excellence at Rehabilitation Services, VA Palo Alto and Clinical Associate Professor (affiliated) at Department of Neurosurgery, Stanford School of Medicine. Adamson completed her undergraduate degrees in neurobiology and women studies at the University of California, Irvine. She completed her Ph.D. in neuroscience from the University of Southern California and a postdoctoral fellowship in Psychiatry and Behavioral Sciences at Stanford School of Medicine.

Dr. Adamson’s expertise and interests span employing translational neuroscience methodologies for diagnostic and neuromodulation treatments (such as repetitive Transcranial Magnetic Stimulation (rTMS)) for frequent health problems in patients with Traumatic Brain Injury (TBI), psychiatric problems, and Alzheimer's disease. She has employed advanced structural and functional imaging modalities and biomarker assessments in Veteran, active military and civilian populations with these health problems. She has been a leader in identifying gender differences in brain injury, particularly in the Veteran population. She currently serves as PI and Site-PI on numerous neuromodulation clinical trials and collaborates internationally for developing advanced diagnostic methods in neuroimaging, especially in underserved communities. In her position at VA Palo Alto, she is actively involved in translating research, such as non-invasive brain stimulation and other therapies, to clinical in-home use by patients using innovations such as virtual and augmented reality.

Dr. Adamson has authored numerous peer-reviewed publications on the cognitive and neural basis of Alzheimer’s disease and on a wide range of topics in TBI. She has received recognition in national and international settings. She is also intricately involved in mentoring research postdoctoral fellows and clinical residents in Physical Medicine & Rehabilitation, Psychiatry and Neurosurgery departments at Stanford School of Medicine. Her goal is to incorporate advanced treatment and diagnostics tailored to each patient's needs into standard-of-care to improve their daily function, reintegration into society and long-term rehabilitation.




Dr Kang received his PhD in Physics and MS in Computer Science from Indiana University Bloomington. He joined the Diagnostic Imaging Science Center at University of Washington in Seattle for postdoctoral research. He worked as an MR Physicist in the Human Cognitive Neurophysiology Laboratory in the Department of Neurology at the University of California at Davis. His tasks were to maintain and modify the sequences for MR research on a 3 T Siemens Verio scanner and a 1.5 T Philips Eclipse scanner and develop new procedures for MR data analysis, statistics, and visualization. He has published 20+ papers to introduce the innovative methods for MR data analysis, including the local landmark method, high-resolution space method, and cortical surface projection mapping method, and automated method to detect brain abnormalities.

In 2017, he joined as an MR Physicist in Palo Alto Veterans Institute for Research (PAVIR) and the Adamson Brain Stimulation Lab in the Department of Neurosurgery at Stanford University. His main tasks are to support the research projects funded by Department of Veterans Affairs and Department of Defense, and administration of windows and linux servers for neuroimaging studies.


VA Polytrauma Postdoctoral Fellow

John obtained his BA in Psychology from UC Berkeley, where he worked in a sleep and psychopathology lab. He then worked in a depression lab at UCSF before entering a PhD program at UCLA, where he conducted research on the relationship between language and thought under the guidance of Dr. Martin Monti. After completing his doctorate in Cognitive Neuroscience, he returned to the Bay Area where he currently is a postdoctoral researcher at the Palo Alto VA in the lab of Dr. Maheen Adamson, where he is developing new treatments for traumatic brain injury, and at Stanford in the Brain Stimulation Lab, where he is developing new treatments for depression. His current focus in both labs is on noninvasive neuromodulation.

Haleh Karbasforoushan, PhD, MS

VA Polytrauma Postdoctoral Fellow

Haleh Karbasforoushan received her Master’s in Computer Science and Brain Modeling at University of Southern California. She then worked at UCLA and Vanderbilt University for a few years, studying brain morphological and functional changes in patients with Schizophrenia and children with Autism, using brain imaging methods. She then joined Northwestern University for her PhD studies in Neuroscience with a specialization in movement disorders. Her PhD research, funded by an NIH NRSA pre-doctoral grant, used brain and spinal cord structural and functional MRI to investigate altered sensorimotor pathways involved in hand impairment post stroke. Haleh’s research in stroke and psychiatric disorders have been published in top journals such as Nature Communications and American Journal of Psychiatry. She currently is a post-doctoral research fellow at Stanford University in the Brain Stimulation Lab, and Palo Alto VA in the lab of Dr. Maheen Adamson. Her postdoctoral research uses advanced MRI and TMS techniques to investigate how brain stimulation can modulate brain functional activity and connectivity in treatment of traumatic brain injury, depression and fibromyalgia.
