Virginia Hayssen earned her Ph.D. from Cornell University.

Research Interests

Pleiotropy of the agouti coat-color locus: examination of the multiple effects a single genetic locus, in this case a gene which influences coat color, can have on the biology of the animal.

Evolution of Reproduction across Mammals: examination of how litter size, gestation length, neonatal length, lactation length are influenced by the physical characteristics of an animal as well as by its ancestry and its habitat and diet.

Women in Science: examination of gender differences in career trajectories of individual who teach or have taught at Smith College. Divisional patterns, departmental differences and changes over time also alter the length of time men and women have occupied particular ranks at the college.
