A mechanical engineer and a plant nutritionist from the University of California, Davis, have been awarded prestigious international research prizes to teach and conduct studies in Germany. Harry A. Dwyer, a professor of mechanical, aeronautical and materials engineering, and Andre Läuchli, a professor in the land, air and water resources department and associate dean of research in the College of Agricultural and Environmental Sciences, each received a U.S. Senior Scientist Award from the Alexander von Humboldt-Stiftung Foundation for their research. The Humboldt award recognizes the recipient's past accomplishments in scientific research and teaching, and pays for one year of research, travel and living expenses at German universities. The goal of the Senior Scientist program is to promote scientific cooperation between the research institutions of the United States and Germany. An expert in the use of computers to study combustion and flow problems, Dwyer will visit the University of Munich during the fall and winter quarters of 1992-93, conducting research on droplet and particle dynamics. During his stay in Munich, he will work with faculty and graduate students and hopes to help introduce researchers to advanced computer simulation techniques. Beginning in August, Läuchli will spend six months at the Technische Hochschule Darmstadt in Darmstadt, Germany, where he will carry out research on the interaction between plants and their environment, particularly the effect of salinity on plants. In addition to his work in Darmstadt, he plans to lecture at other universities throughout Germany. An authority on the responses of plants to environmental stress and on comparative mineral nutrition, Läuchli served eight years as the chair of his department. Due to his current responsibilities as associate dean, he will spend only six months, rather than an entire year, abroad.
