Prof Kenneth Lo obtained his BSc (1993) and PhD (1997) degrees at The University of Hong Kong. His PhD work centred on the design of luminescent transition metal complexes as DNA and metal-ion probes; and the photophysical and photochemical studies of luminescent polynuclear coinage metal chalcogenide complexes. From 1997 to 1999, he worked as a Croucher Foundation Postdoctoral Research Fellow in the research groups of Prof H. Allen O. Hill, FRS and Dr Luet-Lok Wong of the Inorganic Chemistry Laboratory, University of Oxford. He carried out research work on genetic engineering and electrochemistry of cytochrome P450cam and putidaredoxin. Prof Lo joined the Department of Biology and Chemistry of City University of Hong Kong as Assistant Professor in 1999 and became Associate Professor (Scale B) in 2003, Associate Professor (Scale A) in 2007, and Professor in 2011. He is currently the Programme Leader of BSc (Hons) Applied Chemistry/ Chemistry of the Department. He was the Associate Head of the Department from 2010 to 2011. At the College level, he is a member of the College Validation and Monitoring Committee (CVMC) and the College Graduate Studies Committee (CGSC). At the University level, he is currently on the Academic Conduct Committee (ACC) under the Chow Yei Ching School of Graduate Studies.

Prof Lo's research interest is the utilization of luminescent inorganic and organometallic transition metal complexes as biomolecular and cellular probes, with a focus on the development of intracellular sensors, photoactive labels, and bioimaging reagents. He received The APA Prize for Young Scientist from The Asian and Oceanian Photochemistry Association in 2005 and The Distinguished Lectureship Award from The Chemical Society of Japan in 2011. He is currently on the Editorial Advisory Board of Inorganic Chemistry and is an Associate Editor of RSC Advances. He will be one of the Chairs of the Gordon Research Conference Metals in Medicine 201 8. He was awarded a Croucher Senior Research Fellowship from the Croucher Foundation in 2015.
