Leif A. Eriksson
Leif A. Eriksson is a Full Professor of biophysical and theoretical chemistry at Örebro University, Sweden. After his B.S. degree in chemistry at Stockholm University, in 1988, he received his Ph.D. degree in quantum chemistry at Uppsala University, in 1992, followed by postdoctoral period in the lab. of Professor R. J. Boyd, Dalhousie University, Canada. Eriksson is currently the Chair of Örebro Life Science Center and of the Section for theoretical chemistry of the Swedish Chemical Society. His research focus lies in the field of computational modelling of processes and properties of biological systems, primarily computational drug design (development of new photodynamic compounds for tumour treatment, new NSAIDs with reduced phototoxic effects, antidiabetic drugs, and compounds against atherosclerosis), as well as the effects of biological radicals on DNA, antioxidant mechanisms, drug-membrane interactions, and specific enzymatic reactions. The computational tools employed in the research group range from high-level quantum chemistry to MD simulations and bioinformatics tools such as docking and scoring. The group are also extending their work towards the field of multiscale modelling in biochemistry. Eriksson has over 150 scientific publications and more than 20 review papers and book chapters.
