Arielle Woloshin Tolman
Thomas C. Grey Fellow and Lecturer in Law
BioAri’s research interests center on the intersection of criminal law, health law, and constitutional law. Her current project uses mixed empirical methods — analyzing administrative data, interviews, and ethnographic observations — to examine the national scope and consequences of the criminal prosecution of incarcerated people with mental illness for their behavior inside prison. This project received support from the American Bar Foundation, the Horowitz Foundation for Social Policy, and the Kellogg Dispute Resolution Research Center. Ari’s previous scholarship has been published in a broad range of journals including Law and Society Review, Law and Social Inquiry, Northwestern University Law Review, Lancet, and Schizophrenia Bulletin.
Prior to joining Stanford Law, Ari clerked for Judge William A. Fletcher on the U.S. Court of Appeals for the Ninth Circuit and for Justice Goodwin Liu on the Supreme Court of California. She also worked as an associate attorney at Rosen Bien Galvan & Grunfeld LLP in San Francisco, where she represented two classes of incarcerated people in federal court.
Ari graduated summa cum laude from Northwestern University Pritzker School of Law with a JD/PhD in Sociology. She received the John Paul Stevens Prize for highest GPA of graduating law students. While a law student, she served as Editor-in-Chief of the Northwestern University Law Review and worked in the Children and Family Justice Center clinic. Ari received her BA with High Honors in Sociology and High Honors in Neuroscience and Behavior from Wesleyan University. -
Lauren Tompkins
Associate Professor of Physics
Current Research and Scholarly InterestsProfessor Tompkins’s research focuses on understanding the relationships which govern matter’s most fundamental constituents. As a member of the ATLAS experiment at the Large Hadron Collider (LHC), she utilizes the world’s highest energy person-made particle collisions in order to understand the mechanism that gives particles mass, whether or not our current model of elementary particle interactions is a complete description of nature, and if dark matter can be produced and studied in colliders.
In order to search for the exceedingly rare interactions which may provide insight to these questions, the LHC will produce a blistering rate of 50 to 80 proton-proton collisions every 25 nanoseconds in 2015 and beyond. Professor Tompkins works on the design and implementation of custom electronics which will improve the ATLAS experiment’s ability to pick out the collisions which produce the Higgs bosons, dark matter particles and other rare events out of the deluge of ordinary interactions. Her group focuses on particles called heavy flavor fermions, the most massive particles not responsible for mediating interactions. Because they are so heavy, they may have a special connection to the origin of mass or physics beyond our current models of particle interactions.
She is additionally a member of the Light Dark Matter Experiment (LDMX), a proposed experiment to produce and detect dark matter in the laboratory utilizing an accelerated beam of electrons, and the Heavy Photon Search Experiment, which searches for visible decays of dark photons.
Please see her group website for a full description of her research activities. -

Andrea Traynor
Clinical Professor, Anesthesiology, Perioperative and Pain Medicine
BioI completed my training at Stanford University with an Anesthesiology residency in 2003 and Obstetrical Anesthesia fellowship in 2004. I worked in a general private practice for two years at a community hospital in Colorado and was involved in creating protocols for OB related concerns such as non-obstetric surgery during pregnancy and skin to skin contact in the OR during cesarean delivery. I then returned to academic practice and worked for eight years at the University of Colorado and the Colorado Institute for Maternal and Fetal Health. I have collaborated extensively with the Stanford Anesthesia Informatics and Media Lab to create innovative educational tools. These include a major anesthesiology textbook, the Manual of Clinical Anesthesiology, and a comprehensive online learning program for anesthesiology residents called Learnly. I've been the OB anesthesia fellowship director at both the University of Colorado and Stanford University. I truly love guiding fellows from interested residents to consultants in OB anesthesia. My research interests include medical education and topics related to the Obstetrical Anesthesiology workforce.
