Condensed Matter Physics, Physics, Quantum Materials, Superconductors

Nicholas Breznay

Nicholas P. Breznay, PhD, is an experimental condensed matter physicist who studies emergent phenomena in quantum materials. In crystalline and amorphous solids, electrons sometimes decide to spontaneously organize, condense, and rearrange themselves—collectively assembling into patterns and phases that we never would have predicted from a reductionist point of view. These electronic states of matter can […]

Electromagnetics, Physics, Semiconductors, Solid-state Physics, Superconductors

Chih-Yung Chen

Chih-Yung Chen, PhD, studies deep states responsible for the persistent photoconductivity in quantum well structures of Si-doped GaAs, an area of great technological interest because of its potential applications in high-density data storage. Chen’s lab performed the experiment of Shubnikov-deHaas oscillations in magnetoresistance (MR) on a series of delta- GaAs:Si QW structures. From the Shubnikov-deHaas […]

Fluid Dynamics, High-intensity Laser Physics, Physics

Tom Donnelly

Thomas Donnelly, PhD, uses ultrafast laser pulses as a tool for exploring nature. Ultrafast lasers produce pulses that blink on and off in a millionth of a billionth of a second, so a pulse can be used as a stop-motion flash with exquisite time-resolution.  Alternatively, a pulse can be amplified to generate high-intensity light pulses […]

Experimental Cosmology, Physics, Quantum Mechanics, Quantum Theory

Jason Gallicchio

Jason Gallicchio, PhD, specializes in experimental cosmology—the study of the origin and evolution of the universe. Gallicchio spent a year at the South Pole Telescope where he researched polarization of the Cosmic Microwave Background (CMB) and served as a South Pole NSF Station Science Leader. He is also interested in devising new ways to conduct […]

Biomechanics, Biophysics, Physics, Soft Matter Physics

Sharon Gerbode.

Sharon Gerbode, PhD, Iris and Howard Critchell Associate Professor of Physics, researches soft matter physics. While physicists love to simplify the world (think “spherical cow” approximations), many materials evade traditional classifications as either liquid or solid. Such soft materials abound in everyday life; common examples range from biological tissue to sand dunes. Incorporation of soft […]

Biomedical Optics, Biophysics, Laser Physics, Physics, Quantum Optics

Richard Haskell.

Richard Haskell, PhD, Burton G. Bettingen Professor of Physics, specializes in biophysics and biomedical optics with a focus on using lasers to assess the health of living tissue and to engineer artificial tissues. He has designed and built two optical coherence microscopes that image tissue non-invasively and non-destructively and have been used to follow the […]

Elastodynamics, Fast Biomechanics, Fluid Dynamics, Physics, Soft Matter Physics

Mark Ilton

Mark Ilton, PhD, researches the physics of soft matter. Examples of soft matter range from parts of the human body (e.g. skin, blood) to engineered materials (e.g. plastics, rubbers). Ilton is particularly interested in how soft materials can be used to develop green technologies. Currently his team is studying the unloading dynamics of elastic materials […]

Atomic Physics, Physics, Quantum Communication, Quantum Cryptography, Quantum Information Science, Quantum Optics

Theresa Lynn

Theresa Lynn, PhD, specializes in quantum information science. Her research group focuses on quantum communication protocols using photon pairs entangled in polarization and/or spatial mode (orbital angular momentum). Lynn investigates the role of entanglement – a type of correlation that does not exist in classical physics – in providing communication bandwidth and security in protocols […]

Astronomy, Earthquakes, Geophysics, Physics, Rocketry, Seismology, Solar System Astronomy

Greg Lyzenga

Gregory Lyzenga, PhD, Burton Bettingen Professor of Physics, conducts both theoretical and observational studies of the physical processes that lead to earthquakes and tectonic deformation. He uses the Global Positioning System (GPS) to measure the movement of land along fault lines to determine the amount of strain on these faults before earthquakes and the alteration […]

Nonlinear Optics, Physics, Semiconductor Physics, Solar Energy

Peter Saeta.

Peter Saeta, PhD, researches the limits to absorption enhancement in thin-film solar cells from plasmonics. He has investigated the disordering of semiconductors excited by intense femtosecond laser pulses; the generation and applications of sub-picosecond pulses of far-infrared light, including studies of carrier dynamics in semiconductors and superconductors; profiling optical fiber cores using optical scattering techniques; […]

Cosmology, Particle Physics, Physics, String Theory, Theoretical Physics

Vatche Sahakian

Vatche Sahakian, PhD, researches theoretical physics, in particular string theory. Sahakian is interested in understanding the small-scale structure of space in a context where both gravitational dynamics and quantum mechanics become important. This realm often involves studying black holes, unraveling exotic dynamics such as non-commutative geometry, and exploring new frameworks that extend the Standard Model […]

Dark Matter, Physics, Theoretical Particle Physics

Brian Shuve, physics professor at Harvey Mudd College

Brian Shuve, PhD, researches theoretical particle physics. Shuve develops and studies new theories to explain mysteries of the universe, such as the nature of dark matter and why there exists more matter than antimatter. He also devises and implements new experimental tests to learn more about the fundamental constituents and forces of matter. For example, Shuve […]
