Tom Welton

Welton works in the field of sustainable chemistry, and has spent most of his career studying the properties of ionic liquids, their interactions with solutes, and the resulting effects on chemical reactions.[13] He was the world's first Professor of Sustainable Chemistry.[14] His research group also works on applications for these phenomena in developing environmentally safe organic synthesis methods and in the production of biofuels.[1] Ionic liquids became commercially available in 1999, meaning that you 'no longer had to be an expert in the synthesis of ionic liquids to be able to use these in your research'.[15] His 1999 review, Room-Temperature Ionic Liquids. Solvents for Synthesis and Catalysis, has been cited over 13,000 times.[16][17] He is best known for quantifying the effects of ionic liquids on reactions, providing a mechanistic understanding of ionic liquids and establishing how they can be used in organic synthesis.[18][19][20][21] He was also instrumental in linking the fundamental physical properties of ionic liquids to their chemical behaviours.[22]

Along with Peter Wasserscheid, Welton co-edited a book, Ionic Liquids in Synthesis, first released in 2002 with a second edition in 2008.[9] The first edition was reviewed positively as a significant introduction to the then-newly-developing field[23] and the second expanded edition was described as excellent and comprehensive.[24] He also joined Christian Reichardt as an author of the fourth edition of the reference work Solvents and Solvent Effects in Organic Chemistry,[25] reviewed as an important reference for organic chemists.[26]

Welton's work on ionic liquids led to the invention of a method to process wood by separating its chemical component lignin from hemicellulose and cellulose, which is potentially applicable to the efficient production of biofuels.[27] Welton also comments in the media on matters related to the health of the environment, such as the 2012 shortage of helium gas commonly used in research laboratories.[28]

Welton is an advocate for diversity in academic science.[8] In 2013, under Welton's leadership, the Department of Chemistry, Imperial College London was one of four university departments in the United Kingdom to be awarded an Athena SWAN Gold Award in recognition of efforts to promote women in science.[29][30] He supports academic institutions around the world in their efforts to improve diversity and equality. In January 2017 Welton toured Australia to share good practise in supporting academic women.[31]

In 2014, together with Alison Rodger, Welton established the Irène Joliot-Curie conference that looked to develop the careers for women and underrepresented groups in science.[32] The conference included talks from leading women in chemistry, and is now run annually by the Royal Society of Chemistry.[32][33] Welton was appointed to the UKRI Equality, Diversity and Inclusion External Advisory Group.[7] He was awarded an OBE for his services to diversity in education.[34] He has written in the popular media advocating for greater visibility in the sciences for the LGBT community.[6] Additionally, Welton is a L'Oréal-UNESCO For Women in Science male laureate of change, "The time for men to realise that gender parity benefits everyone is long overdue".[35]
