Ph.D. in zoology (endocrinology) from the University of Washington, 1966. Research
interests include environmental endocrinology, investigating roles of natural and
anthropogenic environmental factors (endocrine disruption by metals, pesticides, industrial
pollutants) working through neuroendocrine pathways on thyroid, adrenal, and reproductive
endocrinology of fishes and amphibians in relation to general development, sexual
differentiation and maturation, seasonal reproduction, and aging with emphasis on the roles of
stress hormones. He is the author of a current textbook in endocrinology (Norris, D.O. and
Carr, J.A. Vertebrate Endocrinology, 5th. edition, Academic Press, 2013). A secondary
interest is forensic botany, primarily developing the use of plant cells in the gastrointestinal
tract to aid in homicide investigations (see Bock J.H. and Norris, D.O. Forensic Plant Science,
Academic Press, 2016).
