Bio

Ben received his Ph.D. in 2010 from the University of California, Berkeley where he worked under Stephen R. Leone studying ultrafast electronic relaxation dynamics in atomic systems as well as competitive electronic-nuclear dynamics in superexcited states of small molecules using femtosecond soft X-ray/VUV light sources. From there, he worked under Kenneth B. Eisenthal as a postdoctoral scientist at Columbia University where he developed new approaches to probe reaction kinetics, equilibrium structure, and binding affinities of biological molecules at microparticle interfaces. In 2013 Ben joined ORNL as a Wigner fellow where his research worked to address fundamental questions regarding ultrafast dynamics at, and equilibrium properties of, nano- and macroscopic interfaces. This includes the application and development of nonlinear spectroscopies and microscopies to directly probe surface mediated dynamics and interfacial properties that are central to novel devices and material performance. This research direction has since expanded to study a wide range of emergent chemical and materials problems at interfaces that are addressed using laser based measurements and new approaches to data analysis.
