Anthony Oro, MD, PhD
Eugene and Gloria Bauer Professor
Current Research and Scholarly InterestsOur lab uses the skin to answer questions about epithelial stem cell biology, differentiation and carcinogenesis using genomics, genetics, and cell biological techniques. We have studied how hedgehog signaling regulates regeneration and skin cancer, and how tumors evolve to develop resistance. We study the mechanisms of early human skin development using human embryonic stem cells. These fundamentals studies provide a greater understanding of epithelial biology and novel disease therapeutics.

Franklin M. ("Lynn") Orr, Jr.
Keleen and Carlton Beal Professor in Petroleum Engineering, Emeritus
Current Research and Scholarly InterestsResearch
My students and I work to understand the physical mechanisms that control flow of multiphase, multicomponent fluids in the subsurface, using a combination of experiments and theory. The theory part includes numerical simulation of flow in heterogeneous porous rocks and coalbeds, often using streamline approaches, and it also involves solving by analytical methods the differential equations that describe the interactions of complex phase equilibrium and flow (porous rocks containing more than one flowing phase can sometimes act like a chromatograph, separating components as they flow). The experiments are used to test how well the models describe reality. Applications of this work range from enhanced oil and gas recovery to geologic storage of carbon dioxide (to reduce greenhouse gas emissions) to the transport of contaminants in aquifers.
Teaching
I teach a courses for graduate students on the mathematics of multiphase, multicomponent flow in porous media and on the thermodynamics of phase behavior. I also teach an undergraduate course on energy for freshmen.

Jonathan Osborne
Kamalachari Professor of Science Education, Emeritus
BioMy research focus is a mix of work on policy and pedagogy in the teaching and learning of science. In the policy domain, I am interested in exploring students' attitudes to science and how school science can be made more worthwhile and engaging - particularly for those who will not continue with the study of science. In pedagogy, my focus has been on making the case for the role of argumentation in science education both as a means of improving the use of a more dialogic approach to teaching science and improving student understanding of the nature of scientific inquiry. I have worked on four major projects in argumentation. The first from 1999-2002 was on 'Enhancing the Quality of Argument in School Science Education'. From this we developed the IDEAS (Ideas, Evidence and Argument in Science Education) materials to support teacher professional learning funded by the Nuffield Foundation. From 2007-2010 I was co-PI on the project 'Learning to Teach Ideas, Evidence and Argument in School Science' which explored how to build teachers competency with the use of this pedagogy in four schools. Most recently, I have worked with Mark Wilson of UCB on a project to develop and test a learning progression for Argumentation in science. Some of this work can be found on the website:
http://scientificargumentation.stanford.edu/
My other area of interest in pedagogy is the teaching of reading and the facilitation of discussion. I have published a book entitled 'Language and Literacy in Science Education' and we are just completing a five year IES funded project - 'Catalyzing Comprehension through Discussion and Debate' exploring how we can support the teaching of reading in science. We have developed a web site with some of our materials:
http://serpmedia.org/rtl/
And a MOOC called 'Reading to Learn in Science" which is offered by NovoEd and will be run again from Jan 13, 2016 for 12 weeks.
Finally, much science, if not more, is learned outside the classroom and how young people learn in that environment and what it has to offer formal education is another focus of my work and I was one of the partners in the NSF funded Centre for Informal Learning and Schools (2002-7) and have several publications in this field. -

Nicholas Ouellette
Professor of Civil and Environmental Engineering
Current Research and Scholarly InterestsThe Environmental Complexity Lab studies self-organization in a variety of complex systems, ranging from turbulent fluid flows to granular materials to collective motion in animal groups. In all cases, we aim to characterize the macroscopic behavior, understand its origin in the microscopic dynamics, and ultimately harness it for engineering applications. Most of our projects are experimental, though we also use numerical simulation and mathematical modeling when appropriate. We specialize in high-speed, detailed imaging and statistical analysis.
Our current research includes studies of turbulence in two and three dimensions, with a focus on coherent structures and the geometry of turbulence; the transport of inertial, anisotropic, and active particles in turbulence; the erosion of granular beds by fluid flows and subsequent sediment transport; quantitative measurements of collective behavior in insect swarms and bird flocks; the stability of ocean ecosystems; neural signal processing; and uncovering the natural, self-organized spatiotemporal scales in urban systems. -

Morris M. Doyle Centennial Professor in Public Policy, Emeritus
BioBruce M. Owen is the Morris M. Doyle Professor in Public Policy, Emeritus, in the School of Humanities and Sciences at Stanford University, and the Gordon Cain Senior Fellow, Emeritus, in Stanford's Institute for Economic Policy Research. For a decade ending in 2015 he was Director of the Stanford Public Policy Program. Professor Owen in 2007 led a successful effort to institute a new masters’ degree program in public policy (MPP) at Stanford. He earlier established an international reputation as an expert on antitrust economics, and was the leading academic student of the economics of mass media markets. He is regarded as a principal architect of the 1974 U.S. Department of Justice antitrust lawsuit that led to the eventual dissolution of the old Bell System, and he testified at the trial of the case in 1981. At Stanford, he has taught courses in economic analysis of law, telecommunications law and policy, and political corruption.
Until 2003, Owen was CEO of Economists Incorporated, a Washington DC consulting firm specializing in antitrust and regulatory policy analysis. Before co-founding Economists Incorporated in 1981, he was the Chief Economist of the Antitrust Division of the U.S. Department of Justice and, earlier, of the White House Office of Telecommunications Policy. He was also a faculty member in the Schools of Business and Law at Duke University and the department of economics at Stanford University. Owen was graduated from Williams College in 1965 with a B.A. in economics and from Stanford in 1970 with a Ph.D., also in economics. He was a Woodrow Wilson Fel-low.
Professor Owen was the author or co-author of numerous articles and eight books, including Television Economics (1974), Economics and Freedom of Expression (1975), The Regulation Game (1978), The Political Economy of Deregulation (1983), Video Economics (1992) and Electric Utility Mergers: Principles of Antitrust Analysis (1994). He was an expert witness in several antitrust and regulatory proceedings. In addition to United States v. AT&T, these included United States Football League v. National Football League, and the Federal Energy Regulatory Commission review of Southern California Edison’s proposed acquisition of San Diego Gas and Electric Co.
In 1992 Owen headed a World Bank task force that advised Argentina's government in drafting a new antitrust law. He also advised government agencies in Mexico and the U.S. on telecommunications policy and in Peru on antitrust policy. He was a consultant to the World Bank concerning the economic evaluation of legal and judicial reform projects. His most recent book, The Internet Challenge to Television, was published by Harvard University Press in 1999.
In recent years, Professor Owen has turned to the economic analysis of Madisonian remedies for the adverse effects of lawful political corruption in the U.S. He published “’To Promote the General Welfare' - Addressing Political Corruption in America,” British Journal of Ameri-can Legal Studies, in 2016. He is now working on a book with the working title “Madison’s Missing Branch,” a draft is available at SSRN. -

Marshall Scott Padilla
Acting Assistant Professor, Materials Science and Engineering
Assistant Professor, Materials Science and EngineeringBioMarshall Scott Padilla will begin as an Assistant Professor of Materials Science and Engineering and a Sarafan ChEM-H Institute Scholar at Stanford in September 2026 pending University approval. His research takes a rational-design approach to RNA medicine, engineering lipids and lipid nanoparticles (LNPs) that deliver RNA and proteins to specific cells. Rather than relying on empirical, large-scale screening, he couples the synthesis of structurally defined lipid libraries with multimodal biophysical characterization and in vivo screening to extract the structure–activity relationships that govern delivery.
His research group aims to move beyond the field's default of hepatic delivery toward LNPs that direct RNA and protein cargoes to defined cell types, enabling durable and precise therapies. Group interests span ionizable lipid synthesis, gene editing, cancer immunotherapy, ionic liquids, mapping endosomal escape, and the analytical and biophysical methods needed to relate nanoparticle structure to function. He is broadly interested in establishing generalizable chemical and structural principles for the next generation of delivery vehicles.
Prior to joining Stanford, Marshall was an NIH postdoctoral fellow in the Department of Bioengineering at the University of Pennsylvania with Prof. Michael J. Mitchell, where he developed the Branched ENdosomal Disruptor (BEND) lipid architecture for mRNA and CRISPR-Cas9 delivery (Nature Communications, 2025), advanced solution-based biophysical methods for characterizing LNP structure (Nature Biotechnology, 2025), and engineered LNPs co-delivering mRNA and small-molecule drugs for oral cancer chemoimmunotherapy (Advanced Materials, accepted). He completed his PhD in Chemistry (Chemical Biology) at the University of Wisconsin–Madison and his B.S. in Chemistry at the College of William & Mary. His work has been recognized by the Society for Biomaterials (Burroughs Wellcome Fund BioInterfaces Rising Star Award), the American Association for Dental, Oral, and Craniofacial Research (Hatton Award, postdoctoral first place), and an NIH/NIDCR T90 fellowship. -
