James H. Clark Professor in the School of Engineering and Professor of Chemical Engineering and of Bioengineering
Current Research and Scholarly InterestsProgram Overview
The world we enjoy, including the oxygen we breathe, has been beneficially created by biological systems. Consequently, we believe that innovative biotechnologies can also serve to help correct a natural world that non-natural technologies have pushed out of balance. We must work together to provide a sustainable world system capable of equitably improving the lives of over 10 billion people.
Toward that objective, our program focuses on human health as well as planet health. To address particularly difficult challenges, we seek to synergistically combine: 1) the design and evolution of complex protein-based nanoparticles and enzymatic systems with 2) innovative, uniquely capable cell-free production technologies.
To advance human health we focus on: a) achieving the 120 year-old dream of producing “magic bullets”; smart nanoparticles that deliver therapeutics or genetic therapies only to specific cells in our bodies; b) precisely designing and efficiently producing vaccines that mimic viruses to stimulate safe and protective immune responses; and c) providing a rapid point-of-care liquid biopsy that will count and harvest circulating tumor cells.
To address planet health we are pursuing biotechnologies to: a) inexpensively use atmospheric CO2 to produce commodity biochemicals as the basis for a new carbon negative chemical industry, and b) mitigate the intermittency challenges of photovoltaic and wind produced electricity by producing hydrogen either from biomass sugars or directly from sunlight.
More than 25 years ago, Professor Swartz began his pioneering work to develop cell-free biotechnologies. The new ability to precisely focus biological systems toward efficiently addressing new, “non-natural” objectives has proven tremendously useful as we seek to address the crucial and very difficult challenges listed above. Another critical feature of the program is the courage (or naivete) to approach important objectives that require the development and integration of several necessary-but- not-sufficient technology advances. -
Sho Takatori
Associate Professor of Chemical Engineering
BioPeople say that a picture is worth a thousand words. We think that an equation is worth a thousand pictures. Literally. By collecting and processing data-rich images of complex fluids and matter, we develop “picture-perfect” equations to learn structure-property relationships for new material innovation.
In the Takatori lab, we combine theory, simulation, and experiment to discover mathematical models for complex fluids in engineered and natural environments. We use advanced microscopy and analyze pictures with data-driven methods to understand material properties that bridge the microscopic-to-continuum scales. Our research encompasses soft squishy materials like polymers and liquid crystals, as well as granular matter like sand, powders, and foams.
Outside of research, I have had a strong passion for public speaking since high school, taking speech courses in college and competing in speech contests in Toastmasters International (a professional organization to improve public speaking and leadership skills) for several years as a PhD student. More recently, as a professor and educator, I have channeled my passion for speaking towards science education and technical communication. I have always believed that effective science communication can make broad impacts to society by building public trust in science, promoting data-driven decisions in government and industry, and improving the accessibility of science to underserved communities. I look forward to continue working on effective science communication skills and storytelling techniques with Stanford graduate students and researchers. -

BioReimagining liquid waste streams as resources can lead to recovery of valuable products and more efficient, less costly approaches to reducing harmful discharges to the environment. Pollutants in effluent streams can be captured and used as valuable inputs to other processes. For example, municipal wastewater contains resources like energy, water, nutrients, and metals. The Tarpeh Lab develops and evaluates novel approaches to resource recovery from “waste” waters at several synergistic scales: molecular mechanisms of chemical transport and transformation; novel unit processes that increase resource efficiency; and systems-level assessments that identify optimization opportunities. We employ understanding of electrochemistry, separations, thermodynamics, kinetics, and reactor design to preferentially recover resources from waste. We leverage these molecular-scale insights to increase the sustainability of engineered processes in terms of energy, environmental impact, and cost.

Robert Waymouth
Robert Eckles Swain Professor of Chemistry and Professor, by courtesy, of Chemical Engineering
BioRobert Eckles Swain Professor in Chemistry Robert Waymouth investigates new catalytic strategies to create useful new molecules, including bioactive polymers, synthetic fuels, and sustainable plastics. In one such breakthrough, Professor Waymouth and Professor Wender developed a new class of gene delivery agents.
Born in 1960 in Warner Robins, Georgia, Robert Waymouth studied chemistry and mathematics at Washington and Lee University in Lexington, Virginia (B.S. and B.A., respectively, both summa cum laude, 1982). He developed an interest in synthetic and mechanistic organometallic chemistry during his doctoral studies in chemistry at the California Institute of Technology under Professor R.H. Grubbs (Ph.D., 1987). His postdoctoral research with Professor Piero Pino at the Institut fur Polymere, ETH Zurich, Switzerland, focused on catalytic hydrogenation with chiral metallocene catalysts. He joined the Stanford University faculty as assistant professor in 1988, becoming full professor in 1997 and in 2000 the Robert Eckles Swain Professor of Chemistry.
Today, the Waymouth Group applies mechanistic principles to develop new concepts in catalysis, with particular focus on the development of organometallic and organic catalysts for the synthesis of complex macromolecular architectures. In organometallic catalysis, the group devised a highly selective alcohol oxidation catalyst that selectively oxidizes unprotected polyols and carbohydrates to alpha-hyroxyketones. In collaboration with Dr. James Hedrick of IBM, we have developed a platform of highly active organic catalysts and continuous flow reactors that provide access to polymer architectures that are difficult to access by conventional approaches.
The Waymouth group has devised selective organocatalytic strategies for the synthesis of functional degradable polymers and oligomers that function as "molecular transporters" to deliver genes, drugs and probes into cells and live animals. These advances led to the joint discovery with the Wender group of a general, safe, and remarkably effective concept for RNA delivery based on a new class of synthetic cationic materials, Charge-Altering Releasable Transporters (CARTs). This technology has been shown to be effective for mRNA based cancer vaccines. -

Postdoctoral Scholar, Chemical Engineering
BioI thrive to understand the roles of lysosomes in physiological and pathological conditions. Lysosomes are both degradation compartment and metabolic controlling hub, and dysregulation of lysosomal functions are frequently implicated in a vast number of diseases including neurodegenerative diseases, however, the systematic knowledge of the molecular mechanism by which lysosomal contributes to these diseases is lacking. Ion channels are the primary mediators of neuronal activity, defects in neuronal ion channel activity are linked with many kinds of neurodegenerative diseases. Interestingly, besides typical ion channels that are involved in the neuronal activity, defects in lysosomal ion channels, such as TRPML1, CLN7 and CLC-7 are also implicated in neuropathy. My previous work as Ph.D student in University of Texas MD Anderson Cancer Center focused on regulation of lysosomal function by ion channels and metabolites. I discovered a mechanism of lysosomal Na+ channel regulate mTORC1 activation by regulating lysosomal amino acid accumulation. I also discovered role of glutamine in controlling lysosomal degradation capacity. In the meantime, I developed novel methods to isolate organelles. My ultimate research goal is to understand the key developmental pathways and how alterations in gene sequences and expression contribute to human disease, therefore, I am pursuing independent academic researcher as my career goal. Starting Feb 2022, I work with Dr. Monther Abu-Remaileh at Stanford University on role of lysosomes in neurodegenerative diseases. I use genetics, chemical biology and omics approaches to study lysosome function under various physiological and pathological conditions, especially age-associated neurodegenerative disorders, and monogenic neurodegenerative lysosome storage diseases. In Stanford, I aim to integrate ionic regulation, metabolomic regulation and functional proteomic regulation to systematically understand the biology of lysosome in physiological conditions and pathological conditions.
