Hi, I'm Albert Weiss. I've been on the UNL faculty since 1974, and became a professor emeritus in 2010.

I started my career at UNL at the Panhandle Research and Extension Center in Scottsbluff. For newly two decades, until my retirement in 2010, I taught Crop Growth and Yield Modeling, and Agricultural Climatology. The latter was initially team-taught first with Bill Easterling, then with Steve Hu, and finally by myself on East Campus at UNL. In developing these graduate-level classes, I worked to incorporate the best available knowledge - applying results from my own research, information from recent journals, and from papers presented at professional meetings.

My perspective on simulation modeling deals with the crop as a system. While at UNL, I worked with simulation modeling to study plant development and yield related processes, mainly in winter wheat. Along with others, I also developed a model to simulate plant height in winter wheat.

With the late Eric Kerr, a former plant pathologist at the Panhandle Research and Extension Center, we developed a prediction scheme to determine if it was necessary to spray for a virulent pathogen of sugar beet, Cercospora leaf spot. This system has been in operation for almost 25 years in western Nebraska. This project came about as a result of a sensor that I developed to measure moisture on leaves.

Throughout my career at UNL, I've appreciated the freedom to pursue my own teaching and research interests. Even in retirement, I continue to creatively seek out new ideas to analyze and to write. I am a co-author, along with Thomas R. Sinclair, of a book entitled "Principles of Ecology in Plant Production, 2nd edition" which was published in early 2011.

In the future, I see the incorporation of genomics into crop simulation modeling, and a greater application of crop simulation modeling in explaining phenotypic plasticity, speeding the development of new cultivars, decision-making, and policy studies.
