Senior Lecturer

Biography

Dr Reynisson began his academic career at the University of Iceland where he read chemistry (BSc/MSc). His PhD was obtained from the University of Copenhagen in 2000, the research work was carried out at the Risø national laboratory. He spent two years in Germany as a post-doc at the Max-Planck-Institut für Strahlenchemie. He worked for five years at the Institute of Cancer Research in London as a molecular modeller/computational chemist developing anticancer drug candidates. Before he left the United Kingdom he was a lecturer in chemistry at the Nottingham Trent University. He has visited three institutes for approximately half a year each. These are Worcester Polytechnic Institute (MA, USA), Georgia Institute of Technology (GA, USA) and The University of Leipzig (Germany).

Research | Current

Jóhannes Reynisson’s research interests lie within the field of chemical biology. His main interests are

  • Development of Tyrosyl-DNA phosphodiesterase I (TDP1) inhibitors as anticancer agents

  • Hit to lead development of autophagy inhibitors

  • The use of natural products in conjunction with virtual high throughput screening to identify quality lead compounds

  • Development of pharmacokinetic models based on density functional theory molecular descriptors

  • Investigations into the nature of known drug space

His work is based on building models representing the biological system under investigation. The first step is to validate the theoretical methods by comparing them to experimental data. When this criterion is satisfied the model is used to glean further insight into the phenomenon under investigation.
