James Harris
James and Elenor Chesebrough Professor in the School of Engineering, Emeritus
BioHarris utilizes molecular beam epitaxy (MBE) of III-V compound semiconductor materials to investigate new materials for electronic and optoelectronic devices. He utilizes heterojunctions, superlattices, quantum wells, and three-dimensional self-assembled quantum dots to create metastable engineered materials with novel or improved properties for electronic and optoelectronic devices. His early work in the 1970's demonstrating a practical heterojunction bipolar transistor led to their application in every mobile phone today and record setting solar cell efficiency. He has recently focused on three areas: 1) integration of photonic devices and micro optics for creation of new minimally invasive bio and medical systems for micro-array and neural imaging and 2) application of nanostructures semiconductors for the acceleration of electrons using light, a dielectric Laser Accelerator (DLA), and 3) novel materials and nano structuring for high efficiency solar cells and photo electrochemical water splitting for the generation of hydrogen.

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.

Andrew Hennig
Ph.D. Student in Earth System Science, admitted Autumn 2016
BioAntarctic ice sheet, both of which have exhibited significant mass loss over the past few decades. If the two ice sheets were to fully collapse, they could be responsible for up to 15m of global sea level rise (roughly equal parts from both). This sea level rise would not only pose serious problems for coastal settlements, but cause serious changes to ecosystems, and could profoundly alter the Earth’s ocean circulation.
Current estimates of the mass balance for ice sheets are based primarily on satellite data. This data has become more accurate and more available than ever before, since the 1990s. While estimates can be provided by satellite data, satellites are limited by virtue of the fact that they can only evaluate the surface of the ice shelf. Recent research has shown that a significant amount of the mass loss from the West Antarctic ice sheet is happening underwater, along grounding lines, where deep waters, warmed by global warming, enter the area underneath the ice shelf, and melt the shelves from the bottom. This not only results in mass loss directly, but increases calving of glaciers into the ocean, further accelerating their loss. This melting, below the surface of the ice shelves, cannot be estimated by satellites.
To get a better understanding of the impact of warmer deep waters on glacial retreat in Western Antarctica, we need to measure the melt more directly. Using highly precise measurements of salinity and isotopic composition of seawater in coastal regions of Western Antarctica, we can estimate the amount of glacial meltwater present in the oceanic adjacent to ice sheets. Gaining a greater understanding of the rates and locations of West Antarctic melting will be crucial to developing our understanding of future sea level rise, and other wider impacts. -

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. -

Alexander Honeyman
Postdoctoral Scholar, Earth System Science
BioMy Ph.D. was concerned with the biogeochemistry and recovery of post-wildfire soils. I work at the intersections of data science, field work, laboratory experimentation, biogeochemistry, and microbial ecology. I was exposed to the issue of wildland fire through 10 years of experience as a volunteer firefighter / EMT in Boulder County, Colorado (fire / rescue / EMS). Two current projects are 1) investigating drought and groundwater quality linkages in Colorado, and 2) the geochemical character of wildfire smoke. I love working in environmental systems because they are complex, and offer numerous opportunities to hybridize the physical and computational sciences.
