Wondering what to do after your PhD, or even during it?! Would you like to meet fellow junior researchers to share pains and tales? Or do you just want an official-looking excuse to procrastinate? You are warmly invited to take part in the Meeting for Young Mathematicians in Finland (MYMF). This networking event, organised by […]

The "Helsinki walnut" dataset
Our research group has made an open access dataset for image reconstruction available at the following link: www.fips.fi/dataset.php The measurement data was collected and documented by K. Hämäläinen, L. Harhanen, A. Kallonen, A. Kujanpää, E. Niemi and S. Siltanen. Our group used the walnut data for testing several tomographic reconstruction algorithms, as you can see […]
EXTREMA COST action: live from Leiden
This week I am taking part to the workshop at Lorentz Center (Leiden, The Netherlands) "Artefacts in X-ray tomography". The workshop is part of the COST action, a European framework that allocates funds for multidisciplinary innovative projects, stimulating an active and fruitful collaboration among European researchers and professionals. This is my third workshop of the EXTREMA […]
Creating a voice: a challenging inverse problem (part 2)
(a continuation of this previous post) In this post, I will describe how the human voice is produced and why this is useful to the approach of the Inverse Problems Group at University of Helsinki. Our voice is produced by air flowing from our lungs through our vocal folds and vocal tract. Vocal folds - commonly known as […]
Research idealism VS real world
Have you ever had the experience of a kid who asks you a candid and simple question, that has a complicated answer? The kind of question like "Why we have so much and there are kids starving in India?", where you think "I wish the world was so simple and fair, like the spirit with […]
Creating a voice: a challenging inverse problem (part 1)
This month you can read about an exciting inverse problem on the new issue of Physics World. Professor Samuli Siltanen from University of Helsinki was interviewed regarding the current research in Finland for synthesizing speech and creating artificial voice. This study is part of a big research project in Finland, connecting University of Helsinki, University of Tampere, […]
What if getting cancer is mostly about bad luck?
Few days ago, Science published a groundbreaking research by Tomasetti and Vogelstein from Johns Hopkins University, hinting how getting cancer is significantly a matter of bad luck (*). The authors focus on stem cells and their divisions, and by applying some statistics, show that there is a strong correlation between such repeated process and the development of cancer. […]
Science to masses: why it doesn't work?
Here I am, back from the holidays and ready to go back to my publishing rhythm. This post come quite late with respect to the piece of news that inspired it. Long story short, last November the newly appointed President of the European Commission Jean-Claude Junker eliminated the role of (independent) Chief Scientific Adviser after […]
Transmission eigenvalues: promising for applications? (part II)
I have been working with transmission eigenvalues for the past 2 years, before turning to sparse tomography. If you do not know what I am talking about, read this brief introduction first. A breakthrough in such field was reached when the question whether transmission eigenvalues and non-scattering energies coincide or not (*) was solved. The […]
3 time-saving LaTeX resources you may have not heard of
Since I spent last week at Inverse Days, the last 3 writing a conference paper from scratch and the past month organising in my spare time a Gala for the Italian Association in Finland, I thought of sharing some light contents this week. Hopefully from the next I will be on total holiday and with […]
