Corollary research questions with domestic canines:
- Methodological challenges to current popular methods.
- Naturalistic and ecologically valid scent processing for performance and accuracy.
- Natural action patterns in scent processing.
- Natural and conditioned sniffing.
- Olfactory enrichment.
Research methodology, ideology and theoretical influences:
- Non-invasive neuroscience behavioural neuroscience: Non-invasive measures of physiological correlates of behaviour.
- Unobtrusive/non-intrusive behavioural studies of wildlife in natural environments.
- Sequential analysis of behaviour. Spatio-temporal patterns in behavioural events.
- Small-n and n-of–1 research designs, time series analyses, idiographic research.
- Classical ethology, communication and information theories, zoosemiotics.

Other research: behavioural neuroscience research with fish models
- Electro-communication and social behaviour in the elephant nose fish (Gnathonemus petersii).
- Manganese toxicity in zebra fish (Danio rerio).
- Olfactory learning in zebra fish (Danio rerio).
- The mummichog (Fundulus heteroclitus) as sentinel (indicator) species and model systems in behavioural ecotoxicology (to investigate neurotoxins and endocrine disrupting chemicals).
- Olfactory (classical conditioning) with terrestrial gastropods (pulmonates): Cepaea hortensis, Limax maximus
All the canine (dog) research is done with pets, i.e., dogs volunteered by their owners (with owners giving informed consent for participation similar to research conducted with children). No dogs are acquired for the sole purpose of being used in research projects. No dogs are kennelled, temporarily or permanently, in the Life Science Centre or in my laboratory. Some dogs may spend a day or half a day in the lab but will be given frequent walks by lab staff and volunteers and will always be returning home later in the day. All research carried in my laboratory is non-invasive, does not require sleep, water or food deprivation and induces no anxiety or stress.
- Some of the canid research is or was in collaboration with John Fentress (deceased, formerly from Dalhousie University), Fred Harrington (retired, formerly from Mount Saint Vincent University), Peter McLeod (retired, formerly from Acadia University), Barbara Molnar (Ph.D. candidate, Université de Neufchâtel), Soren Bondrup-Nielsen (Acadia University).
- The reptile research (Current: Nova Scotia ribbon snake, Blanding’s turtle, wood turtle) is or was in collaboration with Parks Canada (Deborah Austin, Stephen Flemming), and Environment Canada (HSP) / Acadia University (Stephen Mockford and Tom Herman).
- The Fundulus research was in collaboration with Shannon Bard (ecotoxicologist, Environmental Programme, Dalhousie); the Danio research was in collaboration with Roger Croll and Alan Fine (both in Physiology and Biophysics, Dalhousie); the Gnathonemus research was in collaboration with Leslie Phillmore (Psychology and Neuroscience, Dalhousie).
