Nominator's project description

Dr. Roche is an outstanding scientist in the field of Theoretical Nanosciences with a broad experience in studying quantum transport and computational modeling of low dimensional systems and complex materials. He combines a broad variety of theoretical tools. His research activities have yielded cutting-edge achievements in the fields of carbon nanotubes, DNA, 2D graphene, and semiconducting nanowires. During his stay in Dresden, Dr. Roche will - among other topics - concentrate on investigating magnetotransport and quantum Hall effects in low dimensional 2D graphene, and charge transport in DNA.
