Thanks for getting in touch, and for your nice words about my work. Your own work sounds interesting to me. Curiously, there is an MA student in Philosophy here at UBC who is pursuing the Science and Technology Studies research stream whose thesis is on a related subject. His name is Andrew Jones.
While I am accepting graduate students, I will be on sabbatical leave next year. When do you think you would be applying to PhD programs? I would be happy to discuss your graduate plans at some point.
