Dr. Schaeff's training is in behavior and evolutionary biology. Her research interests include behavior, conservation biology, molecular ecology and most recently, human sexual identity – examining the biological foundations of human gender and sexual orientation.
There are data that suggest that some people who identify as trans or transgender and who receive sex hormones as part of their transition may experience a shift in their patterns of attraction, a.k.a. sexual orientation, and/or their gender identities. To social scientists, gender is primarily a social construct, connected to an individual’s sex or patterns of sexual attraction mostly through socially constructed links. To natural scientists, it is partially that and also partially a flexible behavioral trait that evolved because it facilitated obtaining high quality mates and maximizing one’s reproductive success. Investigating whether, and if so how, sex hormones affect sexual identity (gender and sexual orientation) is important both for enhancing our understanding of sexual identity and because it will provide information and insights for transitioning individuals and the practitioners who support them. This work incorporates biological, psychological, and sociological theories and methodologies.

Cathy Schaeff's main research interests are conservation biology, molecular ecology, and behavior. She uses molecular DNA techniques in conjunction with behavioral data to investigate gene flow patterns within and between populations (e.g., right whales and gray whales), determine mating strategies (e.g., penguins, right whales), and understand the evolutionary significance of various behaviors (e.g., fostering). She is also conducting a number of studies on fluctuating asymmetry to determine whether morphological asymmetry is a useful tool for assessing population health in endangered species (right whales, manatees, Sable Island ponies) and recently began studying mate choice in gays and lesbians.
