Curriculum Vitae [PDF]
William joined the Buss Lab in the Fall of 2022. He previously graduated with distinction from the MSc in Psychology, Culture, and Evolution at Brunel University London, where he worked under the supervision of Dr. David Schmitt. He has published primarily on the psychology of incels (involuntary celibates) and those who struggle with mating, including a government-funded project for the UK Commission for Countering Extremism, which he presented at the UK Parliament’s Women and Equalities Committee and to the United Nations Behavioral Insights Hub. Beyond incels, his work spans all aspects of human mating, including the mating psychology that underpins cross-sex friendships and sex doll design, the effect of sexual history on desirability, attractiveness-enhancement strategies, and cross-sex mindreading. He is a guest co-editor of a forthcoming special issue of the journal Evolution and Human Behavior on Evolutionary Perspectives on Singlehood and has received several awards from the International Academy of Sex Research, including Best Student Manuscript in 2024. He also won the American Psychological Association Division 51 Student of the Year award in 2023.

Curriculum Vitae: [PDF]
Sid completed his 4-year MSci in Zoology/Biology from The University of Bristol, UK, in 2017. During his studies he developed an interest in evolution, behavioral ecology, and sexual selection, in a wide range of invertebrate species. Specifically, Sid’s research focused on the evolution of anti-predator adaptations, the evolution of parasitism, social insect foraging dynamics, developmental phenotypic plasticity, and mate preferences. Sid’s focus now centers around human evolutionary psychology; specifically, Sid is interested in: (1) inclusive fitness and familial conflict/cooperation, (2) intrasexual competition and sexual conflict, (3) aggression.
