Annual Summer School on Mathematical Aspects of Data Science

~ shacharlovett

June 22 – July 1, 2026
Singapore
https://ims.nus.edu.sg/events/ma_datascience2026/

This is a summer school targeted primarily at PhD students (and also open to others such as Masters and post-docs), covering the foundations of mathematical tools and techniques in modern data science. The first 5 days (Week 1) will consist of tutorial-style introductions to selected topics in this domain, and the final 3 days (Week 2) will consist of two-part talks covering introductory/tutorial content followed by recent research. This school is the third in the series following Darwin 2024 and Switzerland (Bernoulli Center) 2025.

CCC Test of Time award

~ shacharlovett

The inaugural CCC Test of Time Award recognizes a paper published in CCC that had a significant and long-term impact on the field of computational complexity. Eligible papers are those that appeared in CCC (or Structures, for pre-1996 papers), at least 10 years ago. That is, from CCC 2016 or earlier.

We invite the community to nominate papers. The nomination deadline is March 2, 2026.
