Alvin A. Holder is an associate professor at Old Dominion University in Norfolk, USA. He graduated from the University of the West Indies (UWI), Mona Campus, Jamaica, with a B.Sc. (special chemistry) in 1989 and acquired his Ph.D. in inorganic chemistry in 1994 with Prof. Tara P. Dasgupta. He was a faculty member at the University of the West Indies, Cave Hill Campus, Barbados, and an assistant professor in chemistry at the University of Southern Mississippi, USA. His current research involves transition metal chemistry and he has published more than 65 articles and several textbooks and book chapters. In 2012, he was awarded a NSF Career Award.

Lothar Lilge is a senior scientist at the Princess Margaret Cancer Centre and holds a professorship at the University of Toronto, Canada. He obtained his Diploma in physics from the Johann Wolfgang Goethe University in Frankfurt, Germany, and his Ph.D. degree in biophysics from the Westfaehlische Wilhelms University in Muenster, Germany. Additional training was provided through the Wellman Laboratories of Photomedicine at Massachusetts General Hospital, Boston, USA, and during a post-doc at McMaster University in Hamilton, Canada. His work is focused on photodynamic therapy including the use of ruthenium-based photosensitizers and optical spectroscopy for diagnostic and risk assessment among a range of other biophotonic application in medicine.

Wesley R. Browne is an associate professor at Stratingh Institute for Chemistry at the University of Groningen, The Netherlands, since 2013. He completed his Ph.D. degree at Dublin City University, Ireland, with Prof. J. G. Vos in 2002, followed by a postdoc under the joint guidance of Prof. J. G. Vos and Prof. J. J. McGarvey, Queens University Belfast, UK. Between 2003 and 2007 he was a postdoctoral research fellow in the group of Prof. B. L. Feringa at the University of Groningen. He was appointed assistant professor in 2008. His current research interests include transition metal based oxidation catalysis, electrochromic materials and responsive surfaces. He is an advisory board member for the European Journal of Inorganic Chemistry, Particle & Particle Characterization (both Wiley) and Chemical Communications (RSC). He has (co-)authored over 150 research papers, reviews and book chapters.

Mark A. W. Lawrence was a post-doctoral fellow at Old Dominion University in Norfolk, USA, in the group of Prof. A. Holder. He received his B.Sc. degree in 2006 and his Ph.D. degree in inorganic-physical chemistry in 2011 from the University of the West Indies (UWI), Mona Campus, Jamaica, with Prof. Tara P. Dasgupta. His research interests include synthesis of hydrazones and functionalized pyridyl benzothiazoles, their transition metal complexes and application to catalysis and biological processes.

Jimmie L. Bullock Jr. is a Ph.D. student at the University of Kentucky in Lexington, USA, in the department of Chemistry. He received his B.Sc. degree from Longwood University, Farmville, USA, and his M.S. degree in biological inorganic chemistry from Old Dominion University, Norfolk, USA, in 2013 and 2016, respectively. His research interests include studying activation of signaling pathways induced by non-platinum based chemotherapeutic agents and synthesis of lanthanide sensor molecules.
