Hengameh Zahed, MD, PhD
Clinical Assistant Professor, Adult Neurology
BioDr. Zahed is a board-certified, fellowship-trained neurologist with the Stanford Medicine Movement Disorders Center. She is also a clinical assistant professor in the Department of Neurology and Neurological Sciences.
She diagnoses and treats a wide range of movement disorders including Parkinson’s disease, Huntington’s disease, essential tremor, dystonia, and ataxia. She creates a personalized treatment plan for each of her patients using a variety of treatment options, including pharmacological and non-pharmacological options, deep brain stimulation (DBS) treatment for Parkinson's disease and tremors, and botulinum toxin injections for movement disorders and spasticity.
Prior to joining Stanford University, Dr. Zahed completed a neurology residency and fellowship in movement disorders at University of California, San Francisco (UCSF), where she also earned her MD and PhD in biomedical sciences. Dr. Zahed’s research interests include understanding the genetic and electrophysiological underpinnings of movement disorders and investigating applications of wearable technologies to monitor symptoms and improve the quality of life in patients with movement disorders. She also participates in clinical trials of new therapeutics for Parkinson’s disease and other movement disorders.
Dr. Zahed has published in Movement Disorders, Molecular Genetics & Genomic Medicine, The Journal of Clinical Investigation, American Journal of Human Genetics, Cell, and other peer-reviewed journals. She has presented to her peers at international, national, and regional meetings. These meetings have included the International Congress of Parkinson’s Disease and Movement Disorders, the Hereditary Disease Foundation Symposium, the World Society for Stereotactic and Functional Neurosurgery, and the Society for Neuroscience.
Dr. Zahed is a member of the International Parkinson and Movement Disorders Society. -
Natalie M. Zahr
Assistant Professor (Research) of Psychiatry and Behavioral Sciences (Major Laboratories)
BioNatalie M. Zahr received a graduate education in the basic sciences including the study of neuro- pharmacology, physiology, and anatomy. After completing her graduate training in electrophysiology, she began a postdoctoral fellowship as a magnetic resonance imaging (MRI) scientist. Her work focuses on translational approaches using in vivo MR imaging and spectroscopy in studies of human with Alcohol Use Disorders (AUD) and in rodent models of alcohol exposure with the goal of identifying mechanisms of alcohol effects on the brain. Her human studies include participants with HIV, those co-morbid for HIV and AUD and recently, aging individuals with mild cognitive impairment (MCI). Her position allows her to explore emerging MR technologies and apply them to test relevant hypotheses. Before joining Stanford, she taught at several local institutions including UC Berkeley extension and Santa Clara University where she enjoyed sharing her knowledge and enthusiasm for learning with students.

Jamil Zaki
Professor of Psychology
Current Research and Scholarly InterestsMy research focuses on the cognitive and neural bases of social behavior, and in particular on how people respond to each other's emotions (empathy), why they conform to each other (social influence), and why they choose to help each other (prosociality).

Marguerite Blake Wilbur Professor of Natural Science and Professor, by courtesy, of Physics
Current Research and Scholarly InterestsMy research group is exploring a variety of topics that range from the basic understanding of chemical reaction dynamics to the nature of the chemical contents of single cells.
Under thermal conditions nature seems to hide the details of how elementary reactions occur through a series of averages over reagent velocity, internal energy, impact parameter, and orientation. To discover the effects of these variables on reactivity, it is necessary to carry out studies of chemical reactions far from equilibrium in which the states of the reactants are more sharply restricted and can be varied in a controlled manner. My research group is attempting to meet this tough experimental challenge through a number of laser techniques that prepare reactants in specific quantum states and probe the quantum state distributions of the resulting products. It is our belief that such state-to-state information gives the deepest insight into the forces that operate in the breaking of old bonds and the making of new ones.
Space does not permit a full description of these projects, and I earnestly invite correspondence. The following examples are representative:
The simplest of all neutral bimolecular reactions is the exchange reaction H H2 -> H2 H. We are studying this system and various isotopic cousins using a tunable UV laser pulse to photodissociate HBr (DBr) and hence create fast H (D) atoms of known translational energy in the presence of H2 and/or D2 and using a laser multiphoton ionization time-of-flight mass spectrometer to detect the nascent molecular products in a quantum-state-specific manner by means of an imaging technique. It is expected that these product state distributions will provide a key test of the adequacy of various advanced theoretical schemes for modeling this reaction.
Analytical efforts involve the use of capillary zone electrophoresis, two-step laser desorption laser multiphoton ionization mass spectrometry, cavity ring-down spectroscopy, and Hadamard transform time-of-flight mass spectrometry. We believe these methods can revolutionize trace analysis, particularly of biomolecules in cells. -
