Manu Tamminen is developing and applying single cell genome sequencing techniques to gain improved insights into complex bacterial communities and their role at the emergence of antibiotic resistant bacterial strains. He defended his doctoral thesis at the University of Helsinki and has since carried out his research at MIT and ETH Zürich. He is currently employed as a senior lecturer of genetics at the University of Turku.

Dr. Henri Xhaard, Division of Pharmaceutical Chemistry and Technology, Faculty of Pharmacy, University of Helsinki: “10-year retrospective of the Computational Drug Discovery group at the Faculty of Pharmacy, University of Helsinki”

Host: Tiina Salminen

Coffee at 13:45

Dr. Xhaard obtained his  PhD from the university Åbo Akademi in 2006 under the supervision of Prof. Mark S. Johnson. In 2008 he was selected as principal investigator by the Faculty of Pharmacy, University of Helsinki, where he founded the computational drug discovery group. The group has since developed and is to date composed of 6-8 researchers, and is well integrated in national [1] and international [2] infrastructure around chemical biology.

The group uses computational drug discovery methods, both chemoinformatics and molecular modeling, applied to different therapeutic areas as part of local or international research networks/consortia: sleep disorders (orexin receptors) [3], parasitic (membrane-bound pyrophosphatases) [4] and bacterial (quorum-sensing inhibitors) diseases, neuropathic pain (opioid receptors and toll-like receptors) [5], stem-cell inducers for application e.g. in stroke [6], and in-silico predictive ADME (metabolic proteins, ABC transporters [7,8] and glucoronidation enzymes [9]). These projects include many interdisciplinary components and collaboration for example with pharmacology, molecular biology, medicinal chemistry, and X-ray crystallography.

The group is also working to benchmark and develop existing computational methods [see e.g. 10]. We have a strong expertise with data mining [11,12]. The presentation will include current unpublished research in structural bioinformatics, where we develop novel ways to represent the interaction environment around selected atoms, with broad applications to e.g. score molecular complexes or predict the location of elements (hydrogen atoms, water molecules, metal ions, molecular fragments.. ) absent from crystallographic structures or structural models.
