Dr. T. D. Jacobsen
Dr. Jacobsen received his B.S. from the College of Idaho and his M.S. and Ph.D. in systematic botany from Washington State University. In addition to his administrative and programmatic activities at the Institute, he teaches a course in the Biological Sciences department. He also is a research associate in the Section of Botany at the Carnegie Museum of Natural History and an adjunct scientist in the Pittsburgh Poison Center at Children's Hospital.
Dr. Jacobsen's main research interests include vascular taxonomy, especially of Allium (onion, Liliaceae) in North America, and toxic plants and fungi. A current collaborative project with Institute adjunct research scientist Dr. Edward P. Krenzelok, director of the Pittsburgh Poison Center, is the systematic investigation of pediatric plant poisoning. The project involves the statistical analysis of the clinical data on plant poisonings recorded by the American Association of Poison Control Centers Toxic Exposure Surveillance System (AAPCC TESS) from 1985 to the present.
Two applications for online identification of more than 325 native and exotic vascular plant genera found in North America have been developed by Dr. Jacobsen, Dr. Kiger, Dr. Frederick H. Utech and others in conjunction with the Pittsburgh Poison Center. To aid identification, they produced a directory that contains representative illustrations of all the genera found in the TOXIGEN and ASTERGEN applications. The applications and directory are currently in use at the Pittsburgh Poison Center and are being distributed nationally to poison centers.
