Research areas

stellar evolution, interstellar chemistry, space astronomy

Prof. Kwok's research is mainly on interstellar chemistry and stellar evolution. He is widely recognized for his theory on the origin of planetary nebulae, which has transformed our understanding of the death of Sun-like stars. His more recent accomplishments include the discovery of proto-planetary nebulae, the missing link in our understanding of the late stages of stellar evolution, and the discovery of the unidentified emission feature at 21 microns, which is believed to be an unusual carbonaceous compound. Using space-based infrared telescopes, he has found that organic compounds with aromatic and aliphatic structures can be synthesized rapidly in the late stages of stellar evolution. These star-manufactured compounds are now known to have spread widely throughout the Galaxy and are believed to have played a role in the chemical enrichment of the early solar system.

Prof. Kwok has been a guest observer on most of the leading space and ground-based telescopes, including the Hubble Space Telescope, Infrared Space Observatory, the Gemini Observatories, Canada-France-Hawaii Telescope, United Kingdom Infrared Telescope, and the Very Large Array. More details of current research programs can be found here.

Prof. Kwok has lectured extensively around the world. He has given colloquia at universities and research institutes, lectures at symposia and conferences, and talks to the general public in over 20 countries.

Prof. Kwok has published over 300 articles in professional journals and popular magazines. He has two books published by Cambridge University Press: The Origin and Evolution of Planetary Nebulae in 2000 and Cosmic Butterflies in 2001. His book Physics and Chemistry of the Interstellar Medium (University Science Books, 2007) is used as textbook in many leading universities in the world. His most recent books are Organic Matter in the Universe (Wiley 2011) and Stardust: The Cosmic Seeds of Life (Springer 2013).
