Along with my research projects, a number of personal and professional interests occupy my time:
One of the most successful things I have been involved with is the layman’s book Okanagan Geology, a project initiated and led by Dr. Murray Road. It has been one of the best selling books in the Okanagan Valley and has been adopted as a resource reference by several of school districts in British Columbia. Along with authoring or coauthoring several chapters in the book I was co-chair of the committee that raised funding for the project. Proceeds from the book were used to establish the Kelowna Geology Committee Scholarship for Okanagan students pursuing a university education in the Earth Sciences
Because photographic skills are important in the Natural Sciences and because photography is one of my favorite hobbies, the annual Science Photography Contest was established in the early 1990s. Run with the help of the Earth and Environmental Sciences clubs rules change from year to year but usually involve categories such as Flora, Fauna, Landscapes and Photo-microscopy/photo-telescopy with voting during a get-together/party.
Considering my professional enthusiasm for petrology and mineralogy and that I teach Mineralogy at UBC O, it is not surprising that one of my interests is Gemology. I am particularly enthralled with colored varieties of diamond, corundum (ruby and sapphire), beryl (aquamarine and emerald), tourmaline (indicolite and rubellite) and topaz as well as the upper mantle minerals olivine (peridot) and diopside. Stones in my collection are usually shown to the Mineralogy and Introductory Earth and Environmental Sciences students.
Each year I deliver several talks to service clubs and usually visit two or more elementary, middle- or high schools to talk about the Earth sciences.

Research Interests & Projects
I specialize in using the trace element composition of mafic rocks to study the early history of the Earth and the processes that cause differentiation in recent basalt lava flows. My geochemical toolbox has also opened the door to projects in geoarchaeology (fingerprinting and sourcing artifacts) and wine trace element geochemistry. At the heart of many recent projects is an initial analysis of the data using an exploratory statistical technique called multidimensional scaling. This technique is completely new to geochemistry but provides a powerful tool for finding patterns in giant (many elements & samples) data sets.
