Our research has primarily focused on molecular mechanisms underlying protein themostability; functional, structural and regulatory analyses of molecular machines (i.e., proteasome and molecular chaperonines, small heat-shock proteins); improving stability and activity of enzymes with potential medical uses through rational design and using molecular chaperones; molecular basis of stress response in thermoacidophilic archaea, Thermoplasam volcanium as the model organism.
