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.

Michelle Hill
Postdoctoral Scholar, Earth and Planetary Sciences
BioMichelle's work addresses a fundamental question in exoplanet habitability: determining the minimum planetary size required to maintain an atmosphere, a critical prerequisite for life as we know it. She found that stagnant lid (no plate tectonics) planets Earth sized and below orbiting in the habitable zone (HZ) of a Sun-like star need to be ≥ 0.8 Earth radii to maintain their atmosphere past 1 billion years. As a Stanford Science Fellow, Michelle will advance her research and expand her planetary habitability models to look at how tectonic regime, initial volatile content, stellar type, tidal locking and tidal heating effect the results of whether a planet smaller than Earth can hold onto it's atmosphere. Her faculty host is Laura Schaefer, Assistant Professor in the department of Earth and Planetary Sciences.
Michelle also detects and refines the masses and orbits of exoplanets using a combination of radial velocity (RV), transit and astrometry. She is currently observing 10 known planet systems that have shown indications of additional planets in orbit in order to detect the long period outer companions. These observations have lead to the discovery of 3 planets so far.
Michelle recently completed her PhD in Earth and planetary sciences at the University of California, Riverside, where she developed research on exoplanet habitability while supported by the NASA FINESST award. She lead a catalog paper on the demographics of all the known planets in HZ of their star where she found evidence of the sub-Saturn valley in the HZ. During this time she was also a member of the TESS-Keck Survey (TKS) team that conducted RV followup of TESS Objects of Interest (TOIs) and she lead the discovery paper of TOI-1386 b and c.
Michelle completed her post bachelor honours in astrophysics at University of Southern Queensland, Australia. Here Michelle worked on the occurrence rates of giant exoplanets in the habitable zone of their star and found that while giant planets are less likely to be found in the habitable zone than terrestrial planets, if each giant planet is host to more than one moon then exomoons could be more numerous than terrestrial planets in the habitable zone of their star. This work has direct implications for the fraction of stars in the galaxy that may host habitable terrestrial worlds.
Prior to this Michelle completed her bachelors in physics at University of New England, Australia where she attended San Francisco State University during her year abroad. Here she contributed to a study of the Kepler habitable zone planets where she found that the distribution of planets within the habitable zone closely mirrored the distribution of all known planets. This discovery had major implications for the opportunities of statistical analysis of this relatively small group of habitable zone planets.
Michelle loves flying! She was a commercial pilot before returning to school to study physics. She currently holds an Australian ATPL with plans to (one day!) convert this to an FAA APT. -

Leo Hollberg
Professor (Research) of Physics and of Geophysics
BioHow can we make optimal use of quantum systems (atoms, lasers, and electronics) to test fundamental physics principles, enable precision measurements of space-time and when feasible, develop useful devices, sensors, and instruments?
Professor Hollberg’s research objectives include high precision tests of fundamental physics as well as applications of laser physics and technology. This experimental program in laser/atomic physics focuses on high-resolution spectroscopy of laser-cooled and -trapped atoms, non-linear optical coherence effects in atoms, optical frequency combs, optical/microwave atomic clocks, and high sensitivity trace gas detection. Frequently this involves the study of laser noise and methods to circumvent measurement limitations, up to, and beyond, quantum limited optical detection. Technologies and tools utilized include frequency-stabilized lasers and chip-scale atomic devices. Based in the Hansen Experimental Physics Laboratory (HEPL), this research program has strong, synergistic, collaborative connections to the Stanford Center on Position Navigation and Time (SCPNT). Research directions are inspired by experience that deeper understanding of fundamental science is critical and vital in addressing real-world problems, for example in the environment, energy, and navigation. Amazing new technologies and devices enable experiments that test fundamental principles with high precision and sometimes lead to the development of better instruments and sensors. Ultrasensitive optical detection of atoms, monitoring of trace gases, isotopes, and chemicals can impact many fields. Results from well-designed experiments teach us about the “realities” of nature, guide and inform, occasionally produce new discoveries, frequently surprise, and almost always generate new questions and perspectives. -

Stepfan Huntsman
Ph.D. Student in Geological Sciences, admitted Winter 2022
BioI've had an interest in rocks and fossils since I was a small child, amassing a large collection in my youth, but hadn't considered it a viable career path instead starting my path as a social scientist studying gender and sexuality. My interest in a career in paleontology peaked after finishing my first degree, leading me to pursue a second bachelors degree. While working on my undergraduate at Weber State I discovered a true deep love of plants as well as a curiosity about the methods they use to adapt to new environments, which has lead me to pursuing a doctoral degree here at Stanford University.
