I am an analytical chemist and an educator. I program primarily to perform matrix computations for regression analysis, process signals, acquire data from sensors, and to control devices.

I participate in many open source development communities and Linux user forums. I do contract work for an environmental analytical laboratory, where I am primarily focused on LIMS programming and network administration.

I am a member of several community-interest groups such as the Prince Edward Island Watershed Alliance, the Lot 11 and Area Watershed Management Group, and the Petersham Historic Commission.
