#UofT to increase base funding for PhD students to $40,000 per year 🏫 uoft.me/b3h

And I’ll be supervising a group project on optimal transport.

We had a wonderful time at #FDIG2025! A message dessert plate has been presented to the chair at #informationgeometry editorial board meeting.

It is an honour to present my work in Japan where many ideas were first developed.

Revised version available on arXiv. Now we use data up to Dec 2024.

To me this is my real entry point to information geometry

New version on arxiv.org/abs/2302.05833. Couldn't have done it without help from my student Amanjit who joined as a co-author. Includes new implementations with neural OT. Figure shows our primal and dual displacement interpolations w.r.t. "transport KL-geometry" on the simplex.

🏆Good News. The journal Information Geometry has received its first #ImpactFactor of 🌟1.2🌟! Ranked as Q1 (84th/483) in SCIE/ESCI mathematics journals worldwide.👏👏👏 👉link.springer.com/journal/41884/… cf. CiteScore Elsevier | Scopus 2024: 2.0 Thanks to all our authors, reviewers and editors!

BREAKING NEWS Congratulations to Professor Shun-ichi Amari! 2025 Kyoto Prize Laureates kyotoprize.org/en/laureates/s…

Proud to say that my work on the logarithmic divergence is discussed in Prof. Amari’s survey.

Glad to share that this paper has been accepted for publication at the journal Quantitative Finance.

I've not mentioned it yet on Twitter, but since my department announced it today, I'll do so too. I was promoted to Full Professor 🎉 (effective July 2024, in fact). Those of you who are professors will know how critical mentors and students are to our success, and this is very

Finally, this paper has been published at IEEE Transactions on Information Theory. Very proud of Cale (now at Monash University) and Amanjit who made this happen. We are honoured to dedicate this work to Prof. Amari. ieeexplore.ieee.org/abstract/docum…

New paper with Steven Campbell who was my PhD student at U of T. The excess growth rate is a fundamental logarithmic functional in portfolio theory. We connect it with various information-theoretic concepts and provide three axiomatic characterization theorems!
