Miki Yu
Assistant Director, Strategic Outreach, Precourt Institute for Energy
BioMiki Yu joined Precourt Institute for Energy (PIE) as an Event and Outreach Program Planner. In this role she will help shape the programs that PIE, TomKat Center and GCEP offer as they build greater visibility within the Stanford community, the energy community at large, and throughout the world.
Miki started at Stanford working for the Office of Development in 2002, where she reported to the Vice President’s office. She then joined the Stanford Challenge Campaign as an initial team member, working with OOD partners and engaging volunteers and donors at every stage to build and direct momentum for The Stanford Challenge campaign. She was instrumental in executing the Leading Matters component of the campaign, which achieved record breaking attendance and engagement results. -

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.

Megan Zhang
Science and Engineering Associate, Oceans
BioHello! My name is Megan and I am a Science and Engineering Associate supporting oceans research at Hopkins Marine Station, which is Stanford University's marine research institute located in Pacific Grove. I have always had a holistic interest in designing the brains of hardware systems while also figuring out how they interface best with people and their surrounding environment. I also enjoy applying skills such as user-centered product design, rapid prototyping, systems testing, embedded programming, and technical communication to my work.
From my previous experiences, I have worked on hardware systems both independently and in teams across academic, industry, and startup settings--from developing methane detection and mitigation tools at a startup born from a Berkeley research lab, to testing thermal and mechanical reliability of CPUs in the semiconductor industry. I have also worked with a range of sensors and instrumentation, whether for more hands-on projects like autonomous vehicle navigation or more theoretical projects like researching and co-authoring a mission concept proposal through a NASA summer program. Much of my work has explored topics such as health technology, transportation systems, and sustainability, which reflects my broader interest in projects that connect biology, engineering, and planetary health. I am truly excited to learn more about and creatively tackle challenges in marine science, all while collaborating with the Stanford community along the way!
