Colorado is a state of top-level science, stunning nature, and delicious craft beer. My colleague Ville Kolehmainen and I share a love for all three of those. So, when the Finnish embassy in Washington D.C. invited the FAME Flagship to join their delegation to CO, we suited up and flew right in. Day 1. Fort
I served as Harshit Agrawal’s opponent when he defended his doctoral thesis Deep learning-based metal and scatter artifact reduction in cone-beam computed tomography on October 24, 2025 in Aalto University. We had a wonderful scientific discussion. I am so impressed by his creative use of modern AI methods in medical X-ray imaging. Especially powerful is
The Applied Inverse Problems Conference, or AIP for short, is the main scientific gathering of my field of mathematics. It happens every two years. I have a special love for this congress series because I was the main organizer of AIP 2015 in Helsinki, Finland. In 2025 it was held in Rio de Janeiro, Brazil.
Antti Mikkonen of Finnish Meteorological Institute defended his PhD thesis on June 18, 2025, at University of Helsinki. In his work, Antti studied the behaviour of light and other radiation in the atmosphere and developed new computational models for simulation. You can check out his thesis by clicking this link: Computational approach to challenges in
Siiri Rautio defended her PhD thesis Ill-posed microlocal imaging using targeted deep learning at University of Helsinki on April 3, 2025. Her opponent was Professor Elena Loli Piccolomini from University of Bologna. In her work, Siiri made a remarkable tour in the inverse problems landscape. She created new methods for image deblurring, superresolution, X-ray tomography
My old friend and colleague Takanori Ide started as professor at Josai University in Tokyo, Japan, in April 2024. Before that, he worked over 20 years at Aisin AW company, gathering tons of experience in industrial mathematics. Now that he is back in the academic world, he organized a wonderful workshop Inverse Problem Seminar: from
I delivered a talk entitled Electrical impedance tomography and complex geometric optics solutions: new perspectives at the RIMS Symposium Theoretical and numerical approaches for inverse problems in Kyoto, Japan, on January 21, 2025. RIMS is the Research Institute for Mathematical Sciences on the Kyoto University campus. There is a recurrent inverse problems workshop taking place
My student Alexander Meaney defended his PhD thesis Variational Regularization Methods and Open Data for Image Reconstruction in Computed Tomography on January 15, 2025 at University of Helsinki. His opponent was Professor Silvia Gazzola from University of Pisa. .
Inspired by our new FAME Flagship consortium, I put together a writing team for reviewing the amazing history and present highlights of Finnish inverse problems research. The piece was just published in SIAM News. You can take a look here: SIAM News article.
I gave a talk in the applied math seminar at Virginia Tech. My topic was Electrical Impedance Tomography and Virtual X-rays. You can get my slides here: PDF 47MB. My colleague, Assistant Professor Mirjeta Pasha was a wonderful host. She showed me around the campus and introduced me to the Applied & Computational Math research
