Director of a research team on environmental hydrodynamics at the EPFL since 1984, Dr. Ulrich Lemmin was appointed professor with tenure at the EPFL by the Swiss Federal Institute of Technology Board during their meeting of 8/9 September 2005.

Of German nationality, Dr. U. Lemmin obtained his Diploma degree in Mechanical Engineering from the University of Karlsruhe in 1968 and a «Master of Applied Sciences» from University of Waterloo in Canada. PhD in «Atmospheric Sciences and Limnology» from the State University of New York, Albany, USA, he took part in the International Field Year of the Great Lakes, then worked until 1978 as a researcher on mixing and transport problems in rivers at the Federal Institute of Hydraulic Constructions in Karlsruhe. From 1978 to 1984 he studied the hydrodynamics of lakes at EAWAG in the framework of an extensive Swiss national program, «Fundamental problems of the water cycle in Switzerland».

In collaboration with other international researchers, his contributions focus on the study of energy and masses fluxes in lakes and rivers, with the aim of improving concepts of sustainable development of water resources. In order to achieve this, he has developed several measurement techniques, notably the Doppler acoustic profiler, an instrument that is unique in the world. The results of his work are documented in more than sixty scientific publications.

Supervisor of numerous theses and lecturer in environmental hydraulics on the Master's level, he also participates in the Master's program, «Natural sciences in the environment» at the University of Geneva.
