We are part of the Department of Chemistry which is part of the School of Natural Sciences.

Our lab is in the Department of Chemistry where we are part of the Organic Chemistry Research Group

Our research group has interests in synthetic and biological chemistry encompassing methodology, target synthesis, carbohydrate chemistry of various types, carbohydrate chemical biology, biocatalysis and heterocyclic chemistry.

Our group has developed new routes to complex heparin-related oligosaccharides, including the first gram scale routes to 12-mers, access to the longest heparin-related oligomers (up to 40-mer) and identifying single site sulfation control of in vitro and in vivo biological responses to synthetic long heparin-like molecules. This technology underpins ongoing routes to various oligosaccharide-related targets and new applications and techniques for their use for bio-interactions and potentially towards biomedical uses.

We also have interests in other carbohydrate targets through various collaborations (antibacterials, synthetic vaccine targets) and methodology for carbohydrate reactivity.

Interests in the group include organic synthesis but also with applications to chemical biology, and biophysical studies as well as materials chemistry.

We also have considerable experience in heterocyclic synthesis (polybenzimidazoles for example), 3D polyaromatics synthesis, dendrons and also in modified terpenoid synthesis through synthesis and some applications through biocatalysis, for example using enzymes to assist conversion of synthetic non-natural terpenoids to new chiral synths or polymer precursors. We hope to continue these programs and welcome applications from those interested in jointing our lab in those areas of applied organic synthesis.

Charity Activities in May 2022

Having run the Manchester 10K charity event the years before COVID, was hoping to get back in the first live one wit a University of Manchester 'Purple Wave' component this May. But a recurring knee failure means that isn't going to be possible. So, instead have signed dup to two charity May events can likely manage..

Centrepoint "122K steps in May". 122K=number of young people facing homelessness in the UK. The aim is to do 122K on 10 days on May. This will be slightly wobbly as still old walking with limp but its doable.

CRUK "100 push ups a day in May”.  The title says it. Will aim to do at least 100 push ups per day, 7 days a week, in May.

CRUK and Leukemia Research Sponsorship

Prof Peter Gilbert - an academic at Manchester - died of pancreatic cancer a few days before his son’s 11th birthday. A few months later David’s teenage cousin died of leukemia. Peter’s son, David had his hair shaved off in a special School assembly to raise support for cancer charities. His sites below raised money for CRUK or Leukemia research  and hoped would remain open indefinitely for direct donations in memory of his Dad, but just giving may longer allow donations. No llamas were harmed in the making of this haircut.
