I graduated as Master of Architecture from Helsinki University of Technology. After working at architectural offices I have researched and taught history of architecture. I was professor of history of architecture 2007- 2018, now free lancer. I have written on co-operative building in Finland, concrete in 1950s architecture, on interiors and the architecture of 1960s and 70´s and on Alvar Aalto. I have taken part into suburb investigations and into many international co-operations in education. My special love: old cities.
