About


Observing northern lights (aurora borealis) in September 2011.

Work / Research

Since September 2012 I work at the Centre for Metrology and Accreditation (MIKES) with the construction of an optical atomic clock.

My PhD work involved the design/construction and application of an Optical Tweezers instrument 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. Since 2008 I have also sailed a MicroMagic. 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 LinuxCNC(formerly EMC), and how to calculate toolpaths. Together with a friend I've built a 3-axis CNC-mill, and more recently I'm working on a CNC-lathe project. I've made a small contribution to the LinuxCNC project in the form of pyVCP (python visual control panel). I have an experimental C++ library for 3D milling toolpath generation called opencamlib and another for 2D toolpaths called openvoronoi.

I'd like to get better at astrophotography and telescope making.
