Jeremy J. Heit, MD, PhD
Professor of Radiology (Neuroimaging and Neurointervention)
Current Research and Scholarly InterestsOur research seeks to advance our understanding of cerebrovascular disease and to develop new minimally invasive treatments for these diseases. We study ischemic and hemorrhagic stroke, cerebral aneurysms, delayed cerebral ischemia, cerebral arteriovenous malformations (AVMs), dural arteriovenous fistulae, and other vascular diseases of the brain. We use state-of-the-art neuroimaging techniques to non-invasively study these diseases, and we are developing future endovascular technologies to advance neurointerventional surgery.

Chris Heitzig
Postdoctoral Scholar, Epidemiology
BioChris Heitzig is a New Map of Life Postdoctoral Fellow in the Department of Epidemiology and Population Health. An economist by training, his research develops models to examine healthy aging across the life course, with a particular emphasis on identifying causal pathways and key points of policy intervention to improve well-being in later life. A central focus of his work is the socioeconomic impact of undiagnosed metabolic disorders—how these conditions manifest, the costs of leaving them untreated, and the potential for interventions to improve detection and outcomes. His research combines insights from economics and public health with machine learning methods for causal inference.
Before joining Stanford, Chris served in research roles at the Brookings Institution and the World Bank. At Brookings, he managed a $1.5 million research grant investigating how technological change is reshaping employment in Africa. At the World Bank, he designed randomized controlled trials to measure the causal effects of health and employment programs and served in an operational role as the day-to-day lead for a $20 million job transition program. Chris holds a PhD in Economics from the Institute of Development Studies, an MPhil in Economics from the University of Oxford, and a BA in Economics from Saint John’s University. -

Stefan Heller, PhD, MS
Edward C. and Amy H. Sewall Professor in the School of Medicine and Professor of Otolaryngology - Head & Neck Surgery (OHNS)
Current Research and Scholarly InterestsOur research focuses on the inner ear, from its earliest manifestation as one of the cranial placodes until it has developed into a mature and functioning organ. We are interested in how the sensory epithelia of the inner ear that harbor the sensory hair cells develop, how the cells mature, and how these epithelia respond to toxic insults. The overarching goal of this research is to find ways to regenerate lost sensory hair cells in mammals.

Thomas Heller
Lewis Talbot and Nadine Hearn Shelton Professor of International Legal Studies, Emeritus
BioAn expert in international law and legal institutions, Thomas C. Heller has focused his research on the rule of law, international climate control, global energy use, and the interaction of government and nongovernmental organizations in establishing legal structures in the developing world. He has created innovative courses on the role of law in transitional and developing economies, as well as the comparative study of law in developed economies. He has co-directed the law school’s Rule of Law Program, as well as the Stanford Program in International and Comparative Law. Professor Heller has been a visiting professor at the European University Institute, Catholic University of Louvain, and Hong Kong University, and has served as the deputy director of the Freeman Spogli Institute for International Studies at Stanford University, where he is now a senior fellow.

Jacob Hellman
Lecturer
BioI am the Lana H. Ferguson Lecturer in the Program in Science, Technology and Society (STS) at Stanford, where I teach classes about the values that get embedded in innovation and science. Previously, I was a postdoctoral researcher at York University in Toronto. I have also lectured in Sociology and in Communication at the University of California, San Diego.
My research examines how financial technologies generate forms of social belonging, beyond their ostensibly economic function. My book manuscript is about the popularization of amateur venture capital (“angel”) investing. I have also published on Big Tech companies’ data center assets, as part of the project “From Entrepreneurship to Rentiership? The Changing Dynamics of Innovation in Technoscientific Capitalism,” funded by the Social Science and Humanities Research Council (Canada). My research has been published in Economy and Society, Science as Culture, and Historical and Social Research.
Prior to entering a PhD program in Communication at UC San Diego, I had a career in energy conservation insulating low-income housing. -
Martin Hellman
Professor of Electrical Engineering, Emeritus
BioMartin E. Hellman is Professor Emeritus of Electrical Engineering at Stanford University and is affiliated with the university's Center for International Security and Cooperation (CISAC). His most recent work, "Rethinking National Security," identifies a number of questionable assumptions that are largely taken as axiomatic truths. A key part of that work brings a risk informed framework to a potential failure of nuclear deterrence and then finds surprising ways to reduce the risk. His earlier work included co-inventing public key cryptography, the technology that underlies the secure portion of the Internet. His many honors include election to the National Academy of Engineering and receiving (jointly with his colleague Whit Diffie) the million dollar ACM Turing Award, the top prize in computer science. In 2016, he and his wife of fifty years published "A New Map for Relationships: Creating True Love at Home & Peace on the Planet," providing a “unified field theory” for peace by illuminating the connections between nuclear war, conventional war, interpersonal war, and war within our own psyches.
