Amita Kapoor, PhD, Assistant Scientist

Amita Kapoor joined Assay Services in September 2011. She completed her bachelor’s degree in Biology and Psychology at the University of Toronto in 2002. Amita earned her Ph.D. in physiology at the University of Toronto in 2008. Following graduate training, Amita completed a short postdoctoral fellowship at the University of Toronto and then moved to the University of Wisconsin-Madison in 2009 to continue postdoctoral training at the Harlow Primate Laboratory. Amita’s research interests lie in understanding the relationship between hormone exposure during pregnancy and how exposure affects hormone and behaviors during the postnatal period. She has a particular emphasis on using non-invasive measures to assess this relationship. Outside work, Amita enjoys traveling, cooking and spending time with family and friends. Email Dr. Kapoor


Hemanta K. Shrestha, PhD, Senior Research Specialist

Hemanta joined Assay Services in September 2011. His training includes a Bachelor in Veterinary Science (B. V. Sc.; equivalent to DVM) degree from Tamilnadu Veterinary and Animal Sciences University, Chennai, India (1992), a M. Sc. in Tropical Veterinary Science at Edinburgh University, UK(1997), and a PhD in Animal Reproduction from Hiroshima University, Japan (2004). After postdoctoral training at Obihiro University of Agriculture and Veterinary Medicine, Obihiro, Japan, Hemanta moved to the University of Wisconsin-Madison in 2007 to work as a research scientist studying reproductive physiology and endocrinology with a focus on ovarian function including luteolysis in the Department of Dairy Science and as an honorary fellow in the Department of Pathobiology. Hemanta’s role in the Assay Services unit is developing, validating, and conducting radioimmunoassays including radioiodination of proteins and peptides. Hemanta likes to spend time with family and friends. Email Dr. Shrestha


Toni E. Ziegler, PhD, Distinguished Scientist

Toni joined Assay Services in 1994 as Co-Director. In 2005, she became Director of Assay Services. After completing her PhD at Texas A&M University, Toni came to Madison for postdoctoral work in the Department of Psychology and with the Wisconsin National Primate Research Center. She implemented the HPLC based methods for Assay Services and, along with Dan Wittwer, the fecal steroid analyses methods and many urinary assays. Toni continues to develop new assays and preparation procedures for peptides, proteins and steroids and consults on method development and customizing analyses for individual species and biomatrix. Toni enjoys traveling, gardening, cooking and spending time with family and friends. Email Dr. Ziegler
