Prof Kenneth Lo obtained his BSc and PhD degrees at The University of Hong Kong. His PhD work centered on the design of luminescent transition metal complexes as DNA and metal-ion probes, and the photophysical studies of luminescent polynuclear coinage metal chalcogenide complexes. From 1997 to 1999, he worked as a Croucher Foundation Postdoctoral Fellow in the Inorganic Chemistry Laboratory of the University of Oxford. He carried out research on genetic engineering and electrochemistry of cytochrome P450cam and putidaredoxin. Prof Lo joined the Department of Biology and Chemistry (currently Department of Chemistry) of City University of Hong Kong as Assistant Professor in 1999 and became Professor in 2011. His research interest is the utilization of luminescent transition metal complexes as biomolecular and cellular probes, focusing on the development of intracellular sensors, photoactive labels, and bioimaging reagents.
