Miki Yu
Assistant Director, Strategic Energy Alliance, 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. -

Emily Juliette Zakem
Assist Prof (By Courtesy), Earth System Science
BioEmily Zakem is a Principal Investigator at the Department of Global Ecology at the Carnegie Institution for Science. Previously, she was a Simons Foundation Postdoctoral Fellow in Marine Microbial Ecology at the University of Southern California in Los Angeles. She completed her Ph.D. in Climate Physics and Chemistry in the Department of Earth, Atmospheric and Planetary Sciences at the Massachusetts Institute of Technology. In her research, she aims to improve understanding of the connections between microbial ecosystems, global biogeochemistry, and the climate system. She uses theory and mathematical models to understand how microbial ecology drives carbon, nitrogen, and other elemental cycling. She develops broadly applicable models of microbial populations, grounded in underlying chemical and physical constraints, in order to robustly predict the biogeochemistry of past, present, and future environments.

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.
