Fluid dynamics, High-intensity laser physics, Physics

Tom Donnelly

Thomas Donnelly, Ph.D., 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 […]

Biomechanics, Biophysics, Physics, Soft matter physics

Sharon Gerbode

Sharon Gerbode, PhD, 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 matter into modern engineering requires a deeper understanding […]

Biomedical optics, Biophysics, Laser physics, Physics, Quantum optics

Richard Haskell

Richard Haskell, PhD, 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 early development of the frog embryo. […]

Astronomy, Earthquakes, Geophysics, Physics, Rocketry, Seismology, Solar system astronomy

Greg Lyzenga

Gregory Lyzenga, PhD, 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 of the earth afterwards. He […]

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; […]
