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
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).
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 was happy and proud to receive invitation to deliver the Annual Lecture for Students at University of Edinburgh. This is a tradition of popular-math talks. My topic was The Magic of Math: Three-Dimensional X-ray Vision. Here are my slides: PDF 142MB Here I am after the talk with the organizers, Yoyo Yang and Ana
