BioII am the creator and lead director of "Biodesign for Mobile Health" since 2012. This experiential, multidisciplinary, project-oriented course has been named by Stanford's Bioengineering "one of the flagship courses of our Department" and has trained over 200 students in a needs-driven process of mobile health technology innovation. The course is offered by the Stanford Byers Center for Biodesign, where I am working with the leadership group under the direct supervision of Paul Yock, MD, Founder and Director of Stanford Biodesign.
With Stanford Biodesign, I am co-leading Biodesign NEXT, an extension funding program designed to recognize the most promising projects by teams of students from select Biodesign courses through additional mentoring and funds to help advance the ideas towards improving health outcomes. I am also a member of Biodesign's Undergraduate Committee and a mentor to Biodesign Fellows and students from all corners of campus who share a passion for health technology innovation. I am motivated to help advance Stanford School of Medicine's work by faculty and students around Digital Health to foster quality research and facilitate the translation of research ideas into medical practice, industry-specific needs and meaningful health outcomes.
At Stanford, I also have the pleasure to advise on the board of SHIFT, a student initiative aiming to promote and cultivate health innovation on campus by creating a forum for developers, entrepreneurs, and pre-health students to collaborate. A motivated leadership team envisions the group as a platform that connects and empowers students with resources and opportunities to innovate in healthcare. SHIFT fulfills its mission through open roundtable discussions, the TreeHacks Health hackathon and a fellowship program that pairs students as health++ fellows with early-stage companies or faculty-sponsored projects.
When I am not at Stanford, you'll find me consulting, advising or otherwise engaging with and learning from the startup community of Silicon Valley. I am an equity partner at Data Collective VC, managing director and consultant at Medinnovo LLC, and advisory board member of privately-held companies.

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.
