Eric Yin
Temp - Non-Exempt, Human and Planetary Health
BioEric is a MS student in the Epidemiology and Clinical Research Program working under the supervision of Dr. Ashley Styczynski and Dr. Stephen Luby. His thesis explores how natural ventilation can be used to reduce airborne disease transmission in LMIC hospitals and the cost effectiveness of these strategies. Eric is also a Stanford CARE Team Science Fellow, helping undergraduate students develop quantitative skills for applications in Asian precision medicine research.
Prior to graduate school, Eric received his undergraduate degree from the University of Toronto with a major in neuroscience and a double minor in statistics and computer science. His previous research endeavors have involved the exploration of novel MRI biomarkers for Alzheimer's Disease, the localization of hippocampal engram neurons, and the cognitive impacts of surgically induced menopause. -

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 InterestsResearch
My students and I study the surfaces of Earth and planets using radar remote sensing methods. Our specialization is interferometric radar, or InSAR. InSAR is a technique to measure mm-scale surface deformation at fine resolution over wide areas, and much of our work follows from applying this technique to the study of earthquakes, volcanoes, and human-induced subsidence. We also address global environmental problems by tracking the movement of ice in the polar regions. whose ice mass balance affects sea level rise and global climate. We participate in NASA space missions such as Cassini, in which we now are examining the largest moon of Saturn, Titan, to try and deduce its composition and evolution. Our work includes experimental observation and modeling the measurements to best understand processes affecting the Earth and solar system. We use data acquired by spaceborne satellites and by large, ground-based radar telescopes to support our research.
Teaching
I teach courses related to remote sensing methods and applications, and how these methods can be used to study the world around us. At the undergraduate level, these include introductory remote sensing uses of the full electromagnetic spectrum to characterize Earth and planetary surfaces and atmospheres, and methods of digital image processing. I also teach a freshman and sophomore seminar course on natural hazards. At the graduate level, the courses are more specialized, including the math and physics of two-dimensional imaging systems, plus detailed ourses on imaging radar systems for geophysical applications.

Mengye Zhu
Social Science Research Scholar, Doerr School; Senior Scientist, NatCap
BioDr. Mengye Zhu (she/her) is a Senior Scientist at the Natural Capital Alliance and a Social Science Research Scholar at Stanford Doerr School of Sustainability. Her research is focused on climate and environmental policy and political economy, with a particular emphasis on the science–policy interface. She examines key climate discourses, including energy transitions and methane mitigation, with special attention to the roles of “keystone actors,” such as state-owned enterprises. Her work also combines policy analysis with sectoral technical assessments, including leading the development of Global Methane Abatement Solutions Tracker (G-MAST). She has extensive policy engagement experience, supporting high-level climate and environmental dialogues and advancing international collaboration. Before joining Stanford, she worked as an Assistant Research Professor and China Program Co-Director at the Center for Global Sustainability, University of Maryland. She received a Ph.D. in Public Administration from Tsinghua University and a Master's in Public Administration from the University of Pittsburgh.
