Postdoctoral Positions

A Surface Probe Microscopy (STM/AFM) postdoctoral position is available in the Solid/Liquid Interface Group of the Surface Science Center at the University of Pittsburgh. The project is focused on the study of interface dynamics at the atomic and molecular level. Candidates should have previous experience with STM/AFM, especially in electrochemical environments. Experience with lasers is a plus. The candidate should have strong problem solving skills, work well with others and demonstrate scientific leadership and initiative. As we also have Second Harmonic and Sum Frequency projects ongoing, this position is an excellent opportunity to learn more about linear and non linear optical probes of interfaces. The Surface Science Center at the University of Pittsburgh provides an excellent research environment. Our group is interested in chemical and physical processes at solid/liquid interfaces. The laboratory is well equipped with STM/AFM, in addition to nsec, psec, and fsec lasers for linear and nonlinear optical laser experiments.
