Dr. habil. Alexei Krekhov received his PhD in theoretical physics from the Perm State University (Russia) in 1990 studying defects in liquid crystals. During his Humboldt Research Fellowship at the University of Bayreuth from 1994-96 he studied pattern formation in liquid crystals. Starting 1999 he was a researcher at the University of Bayreuth working on pattern formation in complex fluids and soft matter theory. In 2010 he habilitated in theoretical physics at the University of Bayreuth. He joined the MPI-DS in October 2013. His current research interests include nonlinear dynamics in excitable media, two phase convection and modeling of cell motility. He leads the theory group on pattern formation.
