Yilei Wu
Laboratory Services Manager 2, Chemistry
BioAs a research scientist at Stanford University, I am passionate about advancing the field of organic electronics and solar energy conversion. I have over 15 years of experience in designing, synthesizing, and applying novel organic materials for various applications, such as thin-film transistors, solar cells, spintronics, fluorescence imaging, and molecular machines. I work to develop high-performance organic materials for solution printable solar cells and wearable electronics. I leverage my expertise in supramolecular chemistry, thin-film deposition, and device characterization to optimize the donor-acceptor interfaces and bulk morphology of organic photovoltaic materials. My work contributes to the development of flexible and lightweight solar cells that can provide a sustainable and versatile solution for the modern military and civilian needs.
I oversee the operation and management of Chemistry department laboratory teaching facilities. I also oversee and administer health and safety programs and ensure safety compliance.
As instructor, I teach CHEM 100: Chemical Laboratory and Safety Skills. This is a short in-lab course that is only held in the second week of the Autumn quarter. It provides training in basic chemical laboratory procedures and chemical safety to fulfill the safety training requirement for CHEM 121 and more advanced laboratory courses. The following topics are covered: Reading and Understanding Safety Data Sheets (SDS), Exploring Hazards and Risks, Waste Management, Basic Purification (TLC, Extraction, Filtration, etc.) and Analysis Techniques. In spring 2026 I will teach CHEM 121: Understanding the Natural and Unnatural World through Chemistry. -

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.
