Guenter Albrecht-Buehler, is the Robert Laughlin Rae Professor Emeritus at the Feinberg School of Medicine of Northwestern University, USA. Initially trained as a physicist, he received his PhD from the Technische Universität in Munich. His research interests shifted to biology, especially to the study of the locomotion of animal cells, particularly significant for the understanding and treatment of malignancies. While working at the Cold Spring Harbor Laboratory on Long Island, he discovered that the cytoskeletal structures and motile behaviors of sister cells were mirror images of each other, which suggested that the motile behaviour of individual cells was not random, but, rather, pre-determined and realized by an unknown cellular control mechanism. In 1988, he was elected as a Fellow of the Institute for Advanced Studies in Berlin, and as a Fellow of the European Academy of Sciences in Brussels in 2002.
