Metrics for Academic and Research Impact

Prof. Kenneth Lo obtained his BSc (1993) and PhD (1997) 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 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 (currently Department of 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, Professor in 2011, and Chair Professor in 2023.  He is currently the Program Leader of BSc (Hons) Chemistry.  At the College level, he is a member of the College Board.  At the University level, he is the Director of the Talent and Education Development Office.

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 was awarded a Croucher Senior Research Fellowship from the Croucher Foundation in 2015 and was admitted as a Fellow of the Royal Society of Chemistry (FRSC) in 2018.  He also received the CityU College of Science Inaugural Teaching Excellence Award (2021 – 2022) and the CityU Teaching Excellence Award (2022 – 2023).  He was one of the Chairs of the Gordon Research Conference Metals in Medicine 2018 and is the Chair of the 23rd International Symposium of the Photochemistry and Photophysics of Coordination Compounds (ISPPCC 2019).  He was on the Editorial Advisory Board of Inorganic Chemistry (2015 – 2017) and the Advisory Board of RSC Advances (2013 – 2015).  He served as an Associate Editor for RSC Advances (2015 – 2020) and has been an Associate Editor for Inorganic Chemistry since 2020.
