Markus Juvonen defended his PhD thesis entitled Inverse Problems in Photography: From Deconvolution to Dataset Design and Creative Reconstruction on Friday, January 9, 2026 at the University of Helsinki. The opponent was lecturer Jonas Latz from the University of Manchester, UK. Markus’s thesis is remarkable as it paved the way to several directions in photography-related
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.

I spent Monday June 16 in Bologna, Italy, together with my research team. Our colleagues at University of Bologna organized a great one-day scientific workshop on tomographic imaging, including industrial applications. You can see the program here: Workshop on Sustainable Tomographic Imaging with Learning and Regularization. Here are a few photos from the workshop and
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
On January 24, 2025, I delivered a talk in the mathematics seminar at Ehime University in Matsuyama, Japan. The talk was joint with my PhD student Siiri Rautio. Many thanks to Professor Hisashi Morioka for inviting us to beautiful Matsuyama! My talk slides are here for download (PDF 16.6 MB).
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. .
