David Mulvane Ehrsam and Edward Curtis Franklin Professor in Chemistry, Emeritus
BioProfessor Emeritus Hans C. Andersen applies statistical mechanics to develop theoretical understanding of the structure and dynamics of liquids and new computer simulation methods to aid in these studies.
He was born in 1941 in Brooklyn, New York. He studied chemistry as an undergraduate, then physical chemistry as a doctoral candidate at the Massachusetts Institute of Technology (B.S. 1962, Ph.D. 1966). At MIT he first learned about using a combination of mathematical techniques and the ideas of statistical mechanics to investigate problems of chemical and physical interest. This has been the focus of his research ever since. He joined the Stanford Department of Chemistry as Assistant Professor in 1968, and became Professor of Chemistry in 1980. He was named David Mulvane Ehrsam and Edward Curtis Franklin Professor in Chemistry in 1994. Professor Andersen served as department chairman from 2002 through 2005. Among many honors, his work has been recognized in the Theoretical Chemistry Award and Hildebrand Award in Theoretical and Experimental Chemistry of Liquids from the American Chemical Society, as well as the Dean's Award for Distinguished Teaching and Walter J. Gores Award for Excellence in Teaching at Stanford. He has been elected a member of the National Academy of Sciences, and a fellow of both the American Academy of Arts and Sciences and American Association for the Advancement of Science.
Professor Andersen’s research program has used both traditional statistical mechanical theory and molecular dynamics computer simulation. Early in his career, he was one of the developers of what has come to be known as the Weeks-Chandler-Andersen theory of liquids, which is a way of understanding the structure, thermodynamics, and dynamics of simple dense liquids. Later, he developed several new simulation techniques – now in common use – for exploring the behavior of liquids, such as simulation of a system under constant pressure and/or temperature. He used computer simulations of normal and supercooled liquids to study the temperature dependence of molecular motion in liquids, crystallization in supercooled liquids, and the structure of amorphous solids.
Professor Andersen also developed and analyzed a class of simple lattice models, called facilitated kinetic Ising models, which were then widely used by others to provide insight into the dynamics of real liquids. He simulated simple models of rigid rod polymers to understand the dynamics of this type of material. More recently, in collaboration with Professor Greg Voth of the University of Chicago, he has applied statistical mechanical ideas to the development of coarse grained models of liquids and biomolecules. Such models can be used to simulate molecular systems on long time scales. He has also used mode coupling theory to describe and interpret experiments on rotational relaxation in supercooled liquids and nematogens, in collaboration with Professor Michael Fayer of the Stanford Chemistry Department.
Assistant Professor of Chemistry
BioSteven Banik’s research interests center on rewiring mammalian biology and chemical biotechnology development using molecular design and construction. Projects in the Banik lab combine chemical biology, organic chemistry, protein engineering, cell and molecular biology to precisely manipulate the biological machines present in mammalian cells. Projects broadly aim to perform new functions that shed light on regulatory machinery and the potential scope of mammalian biology. A particular focus is the study of biological mechanisms that can be coopted by synthetic molecules (both small molecules and proteins). These concepts are applied to develop new therapeutic strategies for treating aging-related disorders, genetic diseases, and cancer.
Prior to joining the faculty at Stanford, Steven was a NIH and Burroughs CASI postdoctoral fellow advised by Prof. Carolyn Bertozzi at Stanford. His postdoctoral research developed approaches for targeted protein degradation from the extracellular space with lysosome targeting chimeras (LYTACs). He received his Ph.D. from Harvard University in 2016, where he worked with Prof. Eric Jacobsen on synthetic methods for the selective, catalytic difluorination of organic molecules and new approaches for generating and controlling reactive cationic intermediates in asymmetric catalysis.

J.G. Jackson and C.J. Wood Professor of Chemistry, Emeritus
BioJohn Brauman’s research has advanced the understanding of the factors that determine the rates and products of chemical reactions. His primary areas of effort have involved the spectroscopy, photochemistry, reaction dynamics, and reaction mechanisms of gas-phase ions.
John I. Brauman was born in Pittsburgh, PA in 1937. He attended the Massachusetts Institute of Technology (S.B. 1959) and the University of California at Berkeley (Ph.D. 1963). Following a National Science Foundation Postdoctoral Fellowship at the University of California, Los Angeles, he accepted a position at Stanford University where he is now J. G. Jackson - C. J. Wood Professor of Chemistry Emeritus, and serves as Associate Dean of Research. He was previously Department Chair and Associate Dean for Natural Sciences.
Brauman’s work has been recognized in the National Medal of Science, National Academy of Sciences Award in Chemical Sciences, Linus Pauling Medal, Dean's Award for Distinguished Teaching from Stanford University, among many other honors. He is a member of the National Academy of Sciences, American Academy of Arts and Sciences, American Philosophical Society, a Fellow of the American Association for the Advancement of Science, Fellow of the American Chemical Society, and Honorary Fellow of the California Academy of Sciences. He received the 2017 ACS Parsons Award in recognition of his service to public science communication and policy, which includes roles as Deputy Editor for Physical Sciences and Editorial Board Chair for Science magazine, and Home Secretary of the National Academy of Sciences.
Research in the Brauman Group centered on structure and reactivity. Brauman has studied ionic reactions in the gas phase, including acid-base chemistry, the mechanisms of proton transfers, nucleophilic displacement, and addition-elimination reactions. His work has explored the shape of the potential surfaces and the dynamics of reactions on these surfaces. He has made contributions to the field of electron photodetachment spectroscopy of negative ions, measurements of electron affinities, the study of dipole-supported electronic states, and multiple photon infrared activation of ions. He has also studied mechanisms of solution and gas phase organic reactions as well as organometallic reactions and the behavior of biomimetic organometallic species.
BioDr. Megan Brennan's interests include the development of organic chemistry lab courses that give students hands-on opportunities to explore chemistry while reinforcing and building upon concepts learned in lecture classes. She aims for her labs to bring chemistry to life, and to afford students a chance to have fun and experience a taste of scientific discovery.
While studying chemistry at Lafayette College (B.S. 2002), Dr. Brennan worked on the preparation of triazaphenanthrenes and the Oxa–Pictet–Spengler reaction of 1-(3-furyl)alkan-2-ols. She completed her doctoral work at Stanford (Ph.D. 2008), conducting her thesis research in palladium asymmetric allylic alkylation under the advisement of Professor Barry Trost. During her postdoctoral research with Professor Scott Miller at Yale University, she investigated the use of peptides containing a thiazole side chain for use in acyl anion chemistry. She joined the teaching staff at University of California, Berkeley in 2010 before coming returning to Stanford in 2011 to spearhead the development of a new summer organic chemistry sequence, a comprehensive course designed for pre-meds, offering an entire year of organic chemistry in nine weeks.
Dr. Brennan also acts as the liaison to the chemistry majors, to promote events with faculty in both the academic and social aspect: providing an environment that allows students to be comfortable and able to learn, while helping them take advantage of every opportunity that Stanford offers.
Dr. Brennan's current research is in the development classroom experiments that bring cutting edge industrial and academic research into the undergraduate laboratory experience.

Current Research and Scholarly InterestsResearch in our group explores the boundaries of modern organic synthesis to enable the more rapid creation of the highest molecular complexity in a predictable and controllable fashion. We are particularly inspired by natural products not only because of their importance as synthetic targets but also due to their ability to serve as invaluable identifiers of unanswered scientific questions.
One major focus of our research is selective halogenation of organic molecules. Dihalogenation and halofunctionalization encompass some of the most fundamental transformations in our field, yet methods capable of accessing relevant halogenated motifs in a chemo-, regio-, and enantioselective fashion are lacking.
We are also interested in the practical total synthesis of natural products for which there is true impetus for their construction due to unanswered chemical, medicinal, biological, or biophysical questions. We are specifically engaged in the construction of unusual lipids with unanswered questions regarding their physical properties and for which synthesis offers a unique opportunity for study.
