Background:
A. Wüest Ph.D. (1956):
Degree in particle physics at University of Zürich in 1982.
Ph.D. Graduation (ETH Zürich) on deep water mixing in natural
waters in Prof. D. M. Imboden's group in 1987. With a Swiss National
Science Research and Travel Fellowship 1988 at the Applied Physics
Laboratory (UW, Seattle, Prof. M.C. Gregg) for oceanic and estuarine
micro-structure. 1998/99 as a Visiting Scientist at Institute
of Ocean Sciences, Sidney, Canada.
Activity:
Since 1989 leading the Aquatic Physics
Group at EAWAG: Micro-structure-observed small-scale turbulence, benthic boundary
and stratified interior mixing, turbulence modeling, internal wave analysis
and the relation of physical processes to bio-geochemical cycling in lakes
(Aquatic Physics ). Consulting on Lake Restoration,
Lake Aeration and hydropower-related aquatic ecology. Teaching Aquatic Physics
at ETH-Zürich. Head of the department Surface Waters - Research and Management
(SURF). Since
2002 Titular-Professor at ETH-Zürich.
