Karson read psychology as an undergraduate student at UCL and graduated with a First Class Honours degree, achieving a First in all years of study. Upon completing his undergraduate study, he became a postgraduate student in the Department of Psychology at the University of Cambridge. He graduated as the most impactful PhD candidate in his cohort (1st out of 19), ranked by impact factor points accumulated from first-authored empirical research publications. During the final stage of his PhD, he became the only Research Associate funded by St. John’s College and an Affiliated Lecturer in Psychology at Cambridge. Shortly after receiving his PhD, in fall 2020, he became an Assistant Professor at the University of Hong Kong.

In 2020, Karson was one of the only two people outside America to receive an Early Career Achievement Award from the American Psychological Association (APA). In 2021, he was awarded the largest grant in the Early Career Scheme of the Hong Kong Research Grants Council across all subjects, panels, and institutions (1st out of 418 applications).

Karson is on the editorial board of the Archives of Sexual Behavior.


  • Gender similarities and differences in education, health, and work
  • Neurobehavioural effects of sex hormones
  • Causes, correlates, and consequences of childhood gender-related play behaviour
  • Male preponderance in neurodevelopmental conditions such as autism
  • Well-being of sexual and gender minorities including non-heterosexual individuals, transgender and non-binary individuals, and individuals with an “intersex” condition

Psychology and Human Development (PHD) Lab

The PHD lab investigates issues related to gender and sexuality in human development. Research in the lab has included typically-developing individuals, clinical populations, as well as sexual and gender minorities. Our studies cover different developmental stages, from foetal development to adulthood. We aim to test and integrate different theoretical perspectives, such as those concerning genetic, hormonal, neural, cognitive, social, and cultural influences.
