Assistant Professor Chan Kiat Hwa received his doctorate in Chemistry from Princeton University in 2010, under the auspices of an Agency for Science, Technology and Research (A*STAR) National Science Scholarship (PhD), after working on developing chemical tools to explore iron trafficking by Mycobacterium tuberculosis in human macrophages. Thereafter, and prior to joining Yale-NUS College, he carried out postdoctoral research at the Institute of Bioengineering and Nanotechnology, A*STAR, where he worked on exploring the versatile properties of water-based peptide gels in biomaterial applications. His current research interests include probing the impact of select bioorganometallic molecules on cellular processes, as well as the development of water-based organometallic gels for studying gelation. Asst Prof Chan loves badminton and detective fiction, and hopes to promote the detective spirit of inquiry in his classes.
Asst Prof Chan is interested in exploring and developing bioorganometallic compounds for the modulation of cellular processes in select diseases. Carbon monoxide and nitric oxide are known regulators of many cellular processes, so bioorganometallic compounds containing these molecules could modulate cellular responses during disease. However, the detoxification enzymes of the liver can potentially destroy these bioorganometallic compounds. Thus, it is essential to understand the action of liver enzymes on these compounds so that effective bioorganometallic therapeutics can be developed.
Asst Prof Chan is also interested in studying the gelation, as well as molecular self-assembly, of select organometallic compounds. Of particular interest is how various factors, e.g. structural geometry and hydrogen bonding, affect molecular self-assembly and gelation. Such factors can be easily varied in organometallic compounds, thus allowing the curious yet ubiquitous phenomenon of gelation to be studied systematically.
