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 ("Vertebrate Endocrinology, 3rd.
edition, Academic Press 1997). A secondary interest is forensic
botany, primarily developing the use of plant cells in the
gastrointestinal tract to aid in homicide investigations.
