  • Richard Zare

    Richard Zare

    Marguerite Blake Wilbur Professor in Natural Science and Professor, by courtesy, of Physics

    Current Research and Scholarly Interests My 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.

  • Mira Zein

    Mira Zein

    Clinical Assistant Professor, Psychiatry and Behavioral Sciences

    Bio Dr. Zein received her dual bachelor?s degrees in Anthropology and Physiological Science at UCLA and worked initially as a healthcare consultant, developing programs that improve healthcare access for vulnerable populations. She returned to school to pursue a Masters in Public Health at Johns Hopkins University, where she further developed her interests in the intersection of medicine and broader social-cultural themes, particularly the impact on mental health. Her research foci were disaster response interventions for physical and mental health and the impact of the built environment on public health. During her masters, she worked with the International Rescue Committee in Baltimore to help address the acculturation and psychological stress the Baltimore refugee population faced in resettlement.

    In 2010, Dr. Zein began her medical training at McGill University in Montreal, Canada. During medical school she continue to pursue interests in global and cultural health. She represented McGill nationally as the Global Health Advocate in the Canadian Federation of Medical Students, and focused on national and local clinical projects to support refugee and asylum seeker access to medical and mental health treatment. She was awarded the Mona Bronfman Sheckman Prize in Psychiatry for her work. During her psychiatry residency training at New York University (NYU), Dr. Zein continued pursuing her interest in global mental health, working as a group leader for refugees/asylum seekers in the Bellevue Survivors of Torture program, and the Association for Culture and Psychiatry. She also became interested in Integrated Behavioral Health, particularly the University of Washington's Ambulatory Integration of the Medical and Social (AIMs) model, or Collaborative Care Model. She founded the Integrated Behavioral Health resident working group and designed a two-year resident training program in the Collaborative Care Model as well as pioneered other electives in HIV psychiatry and psych-oncology. She completed training in the AIMs model and also was part of an intensive collaborative pilot with the AIMs center to a complete a quality-improvement (QI) project in the Bellevue Hospital primary care site. As part of the two-year resident training program she developed a Collaborative Care model in one of NYU Langone-Brooklyn's FQHC sites. In her last two years of residency she was an APA Leadership Fellow, and served on the APA Consult-Liaison Psychiatry Committee. She worked on a Decisional Capacity Guidelines paper with other committee members, and presented on Consult Liaison educational opportunities and Integrated Behavioral Health Models at the APA conference. She completed residency as a chief resident and won awards for Excellence in Resident Teaching as well as for humanism and clinical excellence in the Comprehensive Psychiatric Emergency Program

    Dr. Zein completed her Consult Liaison Fellowship at Stanford and has remained as clinical faculty. She is currently serving as an attending psychiatrist on the General, Intensive Care, and ED-Psychiatry consult services as well as developing an Integrated Behavioral Health model for the Stanford Primary Care Clinic serving Cisco employees and their families. She is currently working on expanding Integrated Behavioral health to other Stanford Primary Care Clinics, has worked with Stanford's digital health team to start and expand psychiatry e-consults for primary care. She also has taken on a new role as the Behavioral Health Director for Cisco, applying principles of organizational psychiatry and public health to assess company behavioral health strategy

  • Heng Zhao

    Heng Zhao

    Professor (Research) of Neurosurgery

    Current Research and Scholarly Interests My lab is focused on developing novel therapeutic methods against stroke using rodent models. We study protective effect of postconditioning, preconditioning and mild hypothermia. The rationale for studying three means of neuroprotection is that we may discover mechanisms that these treatments have in common. Conversely, if they have differing mechanisms, we will be able to offer more than one treatment for stroke and increase a patient’s chance for recovery.
