Since fall 2016, I'm a regular contributor to the magazine Yliopisto-lehti. I write columns, based on my experiences as a professional, an expat, and even simply as myself. Articles are translated and published in Finnish, but I'll be publishing a translation of my pieces in English here on my blog. The New Witch-Hunt (originally published […]

Women in Mathematics in Finland: Amal Attouchi
As promised, the series of lectures continues, after the inaugural event hosted by the Department of Mathematics and Statistics of University of Helsinki. This time I'll travel to University of Jyväskylä and the guest speaker will be Amal Attouchi, local postdoctoral researcher. Amal graduated in 2014 at Université Paris XIII, with a thesis on PDEs titled […]
Science Slam Helsinki 2015: a triumph for Inverse Problems
Last November I attended a fun event here in Helsinki: a sort of mix between science and stand-up comedy called Science Slam Helsinki. A Science Slam is a form of science communication to general audience. Each scientist gives a short talk (10-15 mins) to popularise science. Often such events are held in non-academic places, like pubs. Science […]
Visual Tips: Cropping multiple images
I think many people in research would confess they waste an unfair deal of time on their presentation visuals or on computer tasks as making a video out of their simulation data, improving quality of images for presentations and such. And how about all those LaTeX fine tricks one needs from time to time and […]
Live from Inverse Days 2015: baby on board
This week I did something a little crazy, dictated by necessity: I took my 2 year old girl to a conference, namely the Inverse Days in Lappeenranta. We drove from Espoo (bad idea) on Monday evening and will stay until Thursday, cutting at half day to get home not too late. Baby-wise it went much […]
Mathematicians Go Hollywood
Did you know that in 2008 a mathematician won an Academy Award? Do you know how to model realistic hair for animation movies or a bomb deflagrating for an action movie? Or you simply need some effective active contour segmentation method? All these questions have in common an effective, yet intuitive, mathematical framework: level set […]
4D tomography: walkthrough of my project - part 3
Here comes the final part of the walkthrough of my current project on dynamic sparse tomography (see also part 1 and part 2). In the previous post I left the question of the choice of the cut-off function hanging. In a classical level set method, would be the Heaviside step function. The Heaviside function is […]
4D tomography: walkthrough of my project - part 2
After talking about motivation (see the first part and then part 3), I will now go into details with the mathematics foundations of the project. The novel tomography reconstruction algorithm I am contributing developing is based on a level set method approach. Level set methods A level set method is an elaborate, yet geometrically intuitive, framework to deal […]
4D tomography: walkthrough of my project - part 1
Last month the greatest event in Inverse Problems ever took place in Helsinki: the Applied Inverse Problems 2015 conference. In addition, I gave my first technical presentation at the 4D tomography minisymposium (find the slides here). I take the chance to write a series of posts as a walkthrough of my project and its current state. The project When […]
The Students' Seminar: what, who and why
Last year I became a chair to the longlasting Students' Seminar (*), together with my colleague Anssi Mirka, at the Department of Mathematics and Statistics of the University of Helsinki. The seminar takes place almost every week of the study periods, usually in room B321 of Exactum, Kumpulan Kampus. Speakers and audience are usually formed by undergrad […]
