Jeff Moses joined the faculty in the School of Applied and Engineering Physics at Cornell University in 2014. Before that, he worked at MIT as a research scientist and principal investigator of federally sponsored research programs in ultrafast laser methods, laser technology and molecular physics. Moses received his Ph.D. from Cornell in 2007, and his B.Sc. from Yale in 2001, with both degrees in Applied Physics. In 2013, he was named an Air Force Office of Scientific Research Young Investigator.

Research Interests

Jeff Moses' research group focuses on capturing "ultrafast phenomena" in real time (i.e., capturing events so brief as to be barely detectable by state-of-the-art technology), and on developing the light-pulse technologies for doing so. We focus on using laser pulses analogously to strobe lights, in order to view brief moments during the coordinated motions of electrons and coupled particles. Such techniques fall under the category of ultrafast nonlinear spectroscopy, and within the purview of the broad field of nonlinear optics.

The shortest laser pulses today, lasting only femtoseconds or attoseconds (millionths or billionths of billionths of seconds) are faster than electronic motion, and can be used to capture the ultrafast events that fundamentally change electronic behavior. Several related questions motivate our work: How fast are the fastest events that serve an important function in the behavior of a material? Can we see them happen? How important are they in determining the real-time behaviors of important systems, like DNA and energy-harvesting devices? Can we determine the conditions under which these ultrafast motions are important?

By endeavoring to connect ultrafast phenomena to real-timescale systems, our work naturally seeks to connect atomic level dynamics to complex chemical and biological processes, and, likewise, to connect quantum mechanical behaviors to phenomena traditionally expected to act classically. The dynamics of photo-excitable systems are one of our main targets, such as DNA photo-damage mechanisms and the initial steps of charge separation in photovoltaics. By learning how these mechanisms work, we hope to gain insights into natural behaviors that can be used to engineer better technologies.
