About

Work / Research

I work with the construction and application of Optical Tweezers at the Electronics Laboratory, Department of Physics, Univeristy of Helsinki.

Hobbies

One of my hobbies is radio sailing in the International One Metre Class. I started in the Marblehead class in 1994 and switched to the IOM around 1999. I like all aspects of the hobby: designing, building, trimming, and racing. I’ve made a list of Model Boats I’ve owned.

I’m also interested in computer aided manufacturing, specifically how to control CNC machines with EMC, and how to calculate toolpaths. I’ve made a small contribution to the EMC project in the form of pyVCP (python visual control panel). My CAM experiments are at google code: monocam.

I’d like to get better at astrophotography.
