Postdoc position Ultrafast X-ray Studies of Chemical Dynamics at Berkeley Lab, Berkeley, California, USA

A postdoctoral research assistant position is available in the group of Oliver Gessner at Lawrence Berkeley National Laboratory. We explore ultrafast dynamics in molecules, clusters, and interfacial systems by means of time-resolved X-ray spectroscopy and imaging techniques. See https://gessnerresearchgroup.lbl.gov/publications for a list of recent publications. The position focuses on the study of ultrafast coupled electronic-structural dynamics in gas phase molecules by means of high-order harmonics enabled femtosecond time-resolved X-ray absorption spectroscopy.[1-3] Further activities may include experimental campaigns at X-ray free electron lasers (X-FELs), synchrotron radiation light sources, and Ultrafast Electron Diffraction (UED) facilities, using a variety of imaging and spectroscopy techniques and targeting a variety of topics ranging from unimolecular reaction dynamics to photoinduced interfacial charge transfer.[4-7] The successful candidate has either recently received or is about to acquire a Ph.D. in physics or chemistry and has extensive hands-on experience with laser-based experiments using high-vacuum sample environments. The candidate is expected to conduct cutting-edge femtosecond laser experiments, develop and apply software-based data evaluation tools, derive theoretical interpretations, and draft manuscripts for publication in peer-reviewed journals, as well as contributions to research proposals and reports to funding agencies. A high degree of self-motivation must be complemented by the capability to thrive in a collaborative group environment. We encourage applications from women, minorities, veterans, and other underrepresented groups presently considering scientific research careers. This opening is for a two year appointment with the possibility of extension, subject to performance and available funding. Applications including a CV and a statement of research interests should be emailed to ogessner@lbl.gov.
