Johan Auwerx is Professor at the École Polytechnique Fédérale in Lausanne, Switzerland, where he directs the Laboratory for Integrated and Systems Physiology (LISP). Dr. Auwerx has been using molecular physiology and systems genetics to understand metabolism in health, aging and disease. Much of his work focused on understanding how diet, exercise and hormones control metabolism through changing the expression of genes by altering the activity of transcription factors and their associated cofactors.
