• Water-Energy Nexus (light-mediated/bio-catalytic water treatment, wastewater-to-energy technologies, solar desalination)
• Sustainable Biogenic Electronics (bio-capacitors, self-powered tactile sensors and e-skins)
• Functional Nanofibers (air-filters, e-textiles, and personal thermal management)

Position(s) Available

We are looking for bright, motivated, and passionate individuals to join our research group. As our work is highly interdisciplinary, we welcome individuals from a variety of different scientific and engineering backgrounds. Desirable backgrounds include but are not limited to Materials Science, Materials Physics, Materials Engineering, Chemistry, Chemical Engineering, Bioengineering, Energy Science/Engineering, Mechanical Engineering, or a related field.

Candidates are expected to have professional working proficiency in the English language, strong interpersonal skills, written and oral communication skills, and the ability to write/contribute to research articles.

Graduate/PhD Students:

Interested candidates should submit their formal application to the School of Energy & Environment, CityU. Information on the school’s admission criteria and application protocols for its research programs is available here

Applicants wishing to join our lab are encouraged to first get in touch with Prof. Sai Kishore Ravi before submitting their formal application.

Post-doctoral Researchers:

We seek highly talented and creative individuals who are passionate about one or more of the four thematic research areas listed above. Candidates must have a PhD degree (graduated preferably within the last 3 years or awaiting graduation after oral defence) in a relevant discipline of Science or Engineering and should have demonstrated a strong potential for high-calibre experimental research in materials science/chemistry/bioengineering, preferably with a publication track record in high-quality journals. The ideal candidate will be a self-starter who can expand the lab’s research expertise and drive new areas of research we have yet to explore.

Undergraduates/Visiting Students/Interns:

We love the idea of dedicated and enthusiastic undergraduates joining our lab. Students must exhibit a willingness to commit time to the pursuit of scientific research and contribute to research publications.

To apply, please submit your CV to Prof. Ravi at skravi@cityu.edu.hk. Review of applications will begin immediately and applications will be accepted until the position is filled. Salary offered will be highly competitive, commensurate with qualifications and experience. For more information, please email Prof. Ravi. Only short-listed candidates will be contacted.
