Yulia Zak, MD, FACS
Clinical Assistant Professor, Surgery - General Surgery
BioDr. Yulia Zak is a board-certified, fellowship-trained minimally invasive and bariatric (weight loss) surgeon. She is also a clinical assistant professor of surgery at Stanford University School of Medicine. Dr. Zak is the program director and unit-based medical director for the Minimally Invasive, Bariatric, and Foregut Fellowship Program.
Dr. Zak specializes in bariatric surgery, foregut (upper digestive tract) surgery, and abdominal wall procedures. Her research is focused on quality improvement measures, surgical education, and bariatric surgery outcomes. She has published her work in numerous peer-reviewed journals, including Obesity Surgery and the Journal of the American College of Surgeons.
Dr. Zak is a fellow of the American College of Surgeons. -
Sandra Zaky
Clinical Associate Professor, Radiation Oncology - Radiation Therapy
BioDr. Zaky is a board certified Radiation Oncologist. She received a Bachelor’s of Science in Biomedical/Electrical Engineering at Marquette University. She worked in research and development as an Engineer, and eventually received a Masters of Science in Immunology from Albany Medical College. Her research thesis focused on a novel therapy to treat hormone-receptor positive breast cancer. She continued to study breast cancer with her research during her Radiation Oncology residency; she integrated her research in the laboratory with her clinical research in triple-negative breast cancer. Since completing residency, she has worked as a general radiation oncologist, and her special interests include breast cancer, skin cancer, CNS tumors and stereotactic radiotherapy.

Astrid Nicole Zamora
Postdoctoral Scholar, Epidemiology
BioDr. Zamora's work examines how social and environmental contexts shape the three pillars of health, diet, sleep, and physical activity, and influence chronic disease risk. Her research integrates epidemiologic methods with community-based participatory approaches to translate findings into evidence-based public health strategies. Her goal is to advance chronic disease prevention and promote heart-healthy aging among Latino/a communities and underserved populations.

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. -
