Benjamin L Doughty

Research Staff Member

Ben received his Ph.D. in 2010 from the University of California, Berkeley where he worked under Stephen R. Leone studying ultrafast electronic dynamics in atoms and small molecules using femtosecond soft X-ray/VUV light sources. From there, he joined the group of Kenneth B. Eisenthal at Columbia University where, as a postdoc, 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 and has since become a full R&D staff member. Ben's present work revolves around two major themes:1) understanding the molecular origins of chemical selectivity at interfaces, especially for chemical separations, using nonlinear optical methods to probe interfacial organization, orientation, and dynamics. 2) developing new tools to probe chemical localization and dynamics in complex living biosystems.
