The members of our interdisciplinary research group are from different departments (biology, biochemistry, chemistry, informatics, mathematics and physics) and different countries (Algeria, Armenia, Belorussia, China, Germany, Italy, Japan, Mexico, U.S.A., India, Serbia, etc). Communication is in English and German.

We run our own Linux cluster which is continuously upgraded. Currently, we have *tens of* dual and single CPU PC's (x86 and AMD64/Opteron) with up to 3.0 GHz connected simultaneously with Gbit switches. Besides our own computer programs we use on the Linux cluster quantum chemical programs such as ADF, GAUSSIAN, JAGUAR, and GAMESS as well as the molecular dynamics program CHARMM.

Code development is done for electrostatic energy computations of proteins with variably charged groups (titratable and redox-active), different approaches for protein structure prediction as well as calculation of free energy of protein association. In cooperation with the CHARMM developer Dr. Milan Hodoscek from Slovenia we included several extensions in the MD simulation program CHARMM.

Current applications focus on photosynthetic systems, proton transfer, enzymes and drugs.
