DENNIS VANENGELSDORP started keeping bees after taking an undergraduate course in beekeeping at the University of Guelph, Canada. Once ‘stung,’ he pursued a master’s degree in apiculture. He has since worked for the Canadian Government as a consultant to the Antigua Beekeepers Cooperative, in the West Indies. He returned north to work at Cornell University as an extensionist where he helped develop their master beekeeping program. The former Acting State Apiarist for the Commonwealth of Pennsylvania, he is currently Assistant Research Scientist at University of Maryland. As one of the founding members of the Colony Collapse working group, he spends considerable time investigating this latest threat to honey bee populations. Dennis is currently at work on a book about bees.
