Metrology Research Institute Doctors' Club

MRI Doctors' club gathers together doctors who have graduated from the laboratory during its existence.

MRI Doctors' club gathers together doctors, who have graduated from Metrology Research Institute during its existence.

The purpose of the club may be summarised as:

  • Meeting the old friends once working with the Institute
  • Exchange of information between the participants
  • Support of graduate students at Metrology Research Institute

The club gathers together once a year. The chairman of the club is presently Dr. Antti Pietiläinen (Nokia) and the secretary is Dr. Petri Kärhä (Aalto). Minutes of the most recent meetings:

Minutes of the older meetings can be found here.

Below you can find the list of doctors that have graduated at Metrology Research Institute, with thesis title in italics. Please note that the list may be outdated in terms of current activities.
