Job Description

Under the guidance of a supervisor, the successful candidate will conduct fundamental research on the mechanisms for the control and manipulation of quantum spin phenomena following light-induced charge transfer events. The results will enable future design of novel quantum information systems. This research is supported by DOE BES grant under the title “Revealing Nature’s Optimized Quantum Spin Coherences in Photosynthetic Proteins“. To reach the research goal, the mechanistic understanding of light-induced quantum phenomena in natural photosynthetic protein systems is required. Photosynthetic proteins are well-defined, experimentally tunable molecular systems with use-inspired complexities and, as such, are ideal model systems for studying creation and control of coherent phenomena. Long-lived electron spin-based entanglement is readily achieved and detected in photosynthetic proteins. This research features a combined use of experimental and theoretical approaches including biochemical and genetic manipulation of photosynthetic proteins, and suite of advanced Electron Paramagnetic/Spin Resonance (EPR/ESR) techniques.

The successful candidate will carry out continuous wave and pulsed, time-resolved EPR experiments on different types of Photosystem I and bacterial Reaction Center proteins. The candidate will characterize electronic structure and spin dynamics of light-induced charge separated states in native, chemically modified, and mutant photosynthetic proteins. In Addition, he/she will analyze data, prepare manuscripts for submission to peer-reviewed publications and make presentations at scientific meetings, maintain comprehensive knowledge of pertinent literature and develop new ideas, concepts, and/or research proposals.

The candidate will join a team of physical chemists and biochemists in the Solar Energy Conversion group and will be mainly involved with advanced pulsed experiments on Bruker ELEXsys E580 and home-built 130 GHz EPR spectrometers.

Education and Experience Requirements

Considerable knowledge of and experimental expertise in advanced EPR spectroscopy, including multi-dimensional pulsed and time-resolved techniques.
Strong interpersonal, verbal, and written communication skills.
Strong skill in data processing, evaluation, and interpretation.
Strong skill in working in an interdisciplinary research team setting.
Some knowledge of and experimental expertise in one or more of the following fields is a plus: application of EasySpin software package, stationary and time-resolved UV/vis absorbance and fluorescence spectroscopy, electrochemistry, handling of photosynthetic proteins.
This level of knowledge is typically achieved through a formal education in bioinorganic chemistry, biochemistry, or biophysical chemistry or related disciplines at the Ph.D. degree level with 0 to 3 years of experience or equivalent in the scientific application of this knowledge and practical laboratory experience.
