THE BIOLOGICAL-ACTIVITY TESTING AND MODELING LABORATORY 

A PLACE WHERE BIOLOGY, CHEMISTRY, AND MATHEMATICS CONVERGE 

General Information: The Biological-Activity Testing and Modeling Laboratory is housed in
the York Veterinary Teaching Hospital at The University of Tennessee Institute of
Agriculture. The laboratory is coordinated by Prof. T. W. Schultz and includes
post-doctoral trainees, technicians, graduate students, and collaborating scientists. The
mission of the laboratory includes the: 1) development, validation, and use of rapid and
inexpensive assays for the evaluation of organic toxicants; 2) development, validation,
and use of structure-activity models for predicting chemical reactivity and toxic
potencies, and 3) advancement of the basic understanding of chemical-biological
interactions. The laboratory has academic ties to the Department of Comparative Medicine
in the College of Veterinary Medicine and the Department of Ecology and Evolutionary
Biology in the College of Arts and Sciences. The laboratory has research ties to the
Center for Environmental Biotechnology. In addition, the laboratory has cooperative
arrangements with several foreign research groups.
