Mohammad Asif Zaman
Physical Science Research Scientist, Hansen Experimental Physics Laboratory (HEPL)
Current Research and Scholarly InterestsMy research focuses on trapping and controlled manipulation of sub-micron sized particles. The work included modeling, fabrication and testing of chips that employ optical forces and/or dielectrophoretic forces to trap and transport nanoparticles. Our goal is to develop lab-on-a-chip systems for biomedical and chemical applications.

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.

Rozie Zangeneh
Physical Science Research Scientist, Program-Mani, A.
BioDr. Rozie Zangeneh is a physical science research scientist in the Department of Mechanical Engineering at Stanford. She develops and utilizes scientific computational tools and conducts massively parallel computations to study detailed physical processes in multiphysics flows and energy systems to develop data-driven low-order models for affordable computation of highly turbulent systems.
Rozie received her Ph.D. in Mechanical Engineering from the University of Maine. Her primary research interests include turbulence modeling (LES and RANS), data-driven and reduced-order models, high-speed aerothermodynamics, and the aerodynamics of wind turbines. -

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. -

Current Research and Scholarly InterestsDiagnosis of coronary artery disease using coronary CT angiography with AI-enabled quantitation of coronary plaque burden and lesion-specific coronary ischemia is used to guide management of CAD. Applying this strategy to PAD patients with no cardiac symptoms reveals a high prevalence of silent coronary ischemia. Ischemia-targeted coronary revascularization may to reduce death and MI and improve long-term survival. Randomized trials in carotid and peripheral vascular patients are underway .
