Dr. Patrick Sit is an assistant professor in the School of Energy and Environment at the City University of Hong Kong. He received his undergraduate degree in Physics from the University of Oxford and Ph.D in Physics from MIT. Prior to joining CityU, he was an associate research scholar in the Department of Chemistry at Princeton University and a post-doctoral associate in the Department of Chemistry at the University of Pennsylvania.
Dr. Patrick Sit is interested in applying state-of-the-art first-principles (ab initio) simulation methods and developing novel computational methodologies to study fundamental reaction processes in energy and environmentally-related problems. Current interests include:
- Density functional theory and first-principles (ab initio) molecular dynamics study and development of catalysts for energy storage and conversion.
- Stability and surface reactions of the hybrid inorganic-organic perovskite materials.
- Graphite intercalation compounds in dual-ion batteries.
- Redox chemistry of transition metal-containing compounds.
- Ab initio molecular dynamics study of structural and dynamical properties of liquid systems.
- Development of novel first-principles methodologies towards more accurate and efficient study of redox and electron-transfer processes
There are currently openings for postdoctoral associates, postgraduate students and research assistants. Experience in first-principles (ab initio) methods and/or molecular dynamics simulations is a plus but not required. Effective written and oral communication skills in English are essential. Postdoctoral associate candidates must have a Ph.D degree in Physics, Chemistry, Materials Science, or a related field at the time of hire. Candidates for postgraduate studentships or research assistant positions must have a Master's or Bachelor's degree in Physics, Chemistry, Materials Science, or a related field at the time of hire.
Successful candidates will conduct research in the computational quantum mechanical study of photovoltaic and electrocatalytic systems with applications in energy. Interested individuals are encouraged to submit their CV to Dr. Patrick Sit, email@example.com . Review of applications will begin immediately and will continue until the positions are filled. Inquires about the positions should also be sent to Dr. Patrick Sit.
City University of Hong Kong is an equal opportunity employer and we are committed to the principle of diversity. We encourage applications from all qualified candidates, especially applicants who will enhance the diversity of our staff.
