Research Interests

My research is in the area of animal cognition, or, more specifically, I use animals as a model to understand cognition in general. My primary focus at present is the role of spatial and temporal information in the organization of animal memory, using a paradigm known as time-place learning (TPL). In TPL the availability of food varies depending on the time (e.g., the time in minutes since the study session began or the time of day) and the place (e.g., location on a radial arm maze). The studies that I am currently involved in are aimed at determining how animals, specifically rats, encode spatial and temporal information in memory. Some researchers have suggested that both animal and human memory may be organized on the basis of spatial and temporal information. In addition to my studies of TPL in animals, I am also beginning an investigation into this ability in children. The focus will be on a comparison between spatiotemporal abilities in humans and non-human animals.

In addition to my work on TPL, I am also interested in the more general spatial and temporal abilities of both animals and humans.

Background

I received my Ph.D. in Psychology from the University of British Columbia under the supervision of Don Wilkie. Upon completion of my Ph.D. I completed a two year NSERC Post-doctoral Fellowship at University College London.

Student Mentoring

Undergraduate: I look forward to the opportunity to supervise Honours projects. Students who are interested in either animal or human cognition, and in particular spatial and temporal ability, should contact me to set up an appointment. Students will receive hands-on experience in all aspects of study design, data collection, data analysis and presentation of research results.

In addition to honours students I am interested in mentoring other psychology undergraduate students who would like to gain some research experience by volunteering in a psychology laboratory. I have found that undergraduates that volunteer in psychology labs find it to be a very rewarding experience.

Graduate: I am currently recruiting graduate students who are interested in conducting research into the temporal and spatial abilities of humans and non-human animals. If your academic research interests are in line with those discussed above, you are encouraged to contact me to discuss the possibility of graduate work in my lab.
