Serge Ducommun, a visiting Master's student in the Department of Biotechnology at the Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland has been awarded a prize for carrying out the best research project in his year. The project was carried out in the MRC protein Phosphorylation Unit at Dundee and co-supervised by Kei Sakamoto, Carol MacKintosh and Shuai Chen. In this project Serge studied the regulation and physiological roles of AS160 and TBC1D1, two RAB GTPases implicated in regulating the trafficking of the insulin-regulated glucose transporter, GLUT4 in muscle and adipose tissue. Serge's Master's degree is coordinated by Professor Johan Auwerx at EPFL.
