Stress signal transduction and cellular responses

Research focus

A key question in biology is how organisms cope with changing environmental conditions. Research in our group focuses on the mechanisms of signal transduction and physiological adaptations in unfavorable environments. We take an integrative approach to better understand fundamental molecular processes at the interface between signal transduction and coordinated responses of cellular metabolism and gene expression in stress situations.
