    Paul S. and Billie Achilles Professor in Environmental Biology, Senior Fellow at the Woods Institute for the Environment and Professor, by courtesy, of Geological Sciences

    Current Research and Scholarly InterestsThe research of Elizabeth Hadly probes how perturbations such as climatic change and human modification of the environment influence the evolution and ecology of vertebrates.

  • Philip C. Hanawalt

    Philip C. Hanawalt

    Dr. Morris Herzstein Professor in Biology, Emeritus

    Current Research and Scholarly InterestsOur current research focuses in two principal areas:

    1. The molecular basis for diseases in which the pathway of transcription-coupled DNA repair is defective, including Cockyne syndrome (CS) and UV-sensitive syndrome (UVSS). Patients are severely sensitive to sunlight but get no cancers. See Hanawalt & Spivak, 2008, for review.

    2. Transcription arrest by guanine-rich DNA sequences and non-canonical secondary structures. Transcription collisions with replication forks.

  • James Harris

    James Harris

    James and Elenor Chesebrough Professor in the School of Engineering and Professor, by courtesy, of Materials Science and Engineering and of Applied Physics

    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. 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.

    BioI am a theorist working on problems in condensed matter, high energy and gravitational physics.

    The anomalous transport behavior of quantum many-body systems --- including unconventional materials such as high temperature superconductors and other 'strange metals', artificial ultracold atomic systems and the strongly coupled quark gluon plasma --- is a longstanding theoretical challenge that I have approached from several angles. I have suggested that transport in these systems may be controlled by fundamental limitations imposed by quantum statistical mechanics. To this end, I have established bounds on quantum transport that connect the macroscopic properties of these systems to quantities such as the local thermalization rate and underlying quantum mechanical `Lieb-Robinson' velocities. In parallel to this ''bird's eye'' approach, I am also increasingly interested in specific scattering mechanisms in unconventional materials that may give a relatively simple explanation of transport behavior that has otherwise been considered anomalous --- using this approach my collaborators and I have 'demystified' aspects of transport in quantum critical ruthenate materials.

    I am also working on understanding aspects of the emergence of spacetime from large N matrix quantum mechanics models. These can be thought of as the simplest models of holographic duality, and will likely hold the key to understanding the emergence of local physics as well as black holes.

    Along with many other theorists, I have found in recent years that the holographic correspondence, the physics of quantum entanglement and quantum field theory more generally have led to strong and unanticipated connections between central concerns in condensed matter and high energy physics.

  • Trevor Hastie

    Trevor Hastie

    John A. Overdeck Professor, Professor of Statistics and of Biomedical Data Sciences

    Current Research and Scholarly InterestsFlexible statistical modeling for prediction and representation of data arising in biology, medicine, science or industry. Statistical and machine learning tools have gained importance over the years. Part of Hastie's work has been to bridge the gap between traditional statistical methodology and the achievements made in machine learning.

  • Patrick Hayden

    Patrick Hayden

    Stanford Professor of Quantum Physics and Professor, by courtesy, of Computer Science

    BioProfessor Hayden is a leader in the exciting new field of quantum information science. He has contributed greatly to our understanding of the absolute limits that quantum mechanics places on information processing, and how to exploit quantum effects for computing and other aspects of communication. He has also made some key insights on the relationship between black holes and information theory.
