Congratulations to Tomasz Kociumaka for winning the prestigious 2025 Presburger Award! An incredibly well-deserved recognition of his brilliant contributions to theoretical computer science! 👏🎖️ #PresburgerAward #TCS mimuw.edu.pl/~kociumaka/ eatcs.org/index.php/pres…
I was honored to deliver the keynote address at the 23rd Symposium on Experimental Algorithms (SEA 2025). My talk, “Algorithms for Modern Processor Architectures,” explored key topics including superscalar execution and SIMD instructions, highlighting their critical influence on…
Love all these "constant time" lookups :)
oops did it again
Proud of my student @AlessioCampa_ who led this work, to appear in WABI ‘25! Check this out for the latest advancements on the Fulgor index: now faster to query and build. 🧬⚡️
With @giulio_pibiri and @nomad421, we are about to release Fulgor v4.0.0, which is much faster to build and query, without affecting its memory efficiency. You can find all the information in our #WABI2025 paper (bit.ly/3T6TWqw). 🧵 (1/7)
We're thrilled to announce that one of our keynote speakers at #WABI2025 will be the inimitable Ben Langmead! wabiconf.github.io/2025/talks/tal…. Ben's keynote is titled "We are what we index; a primer for the Wheeler Graph era", and it's sure to be a whirlwind tour of full-text indexing!
Our lab is hiring! We are looking for a postdoc in the area of immunology/microbiology+ML, or in pure method/software development. More information about our lab at: mourisl.github.io
A monumental collaborative effort with many incredible people ☺️ Proud to be part of this! arxiv.org/abs/2506.06536

Oooh! Congrats boys! 🎉
I am also extremely happy to also share that our paper has received a Distinguished Paper Award at @IEEESSP 2025! A huge thank you to @stecalzavara @claudiolucchese @giulio_pibiri for making this possible!

❓How can we efficiently verify the robustness of machine learning models, particularly boosted tree ensembles? ✨In our ML security paper that I presented today at @IEEESSP we answer to this question! 🔗 computer.org/csdl/proceedin… w @stecalzavara @claudiolucchese @giulio_pibiri
"...one index to rule them all." :)
In the context of responding to reviews for our alevin-fry-ATAC paper, we ended up producing a short note describing the piscem index. While a full piscem paper is still in the works, folks might be interested in this zenodo.org/records/150969…, w Noor, Jamshed & @giulio_pibiri
Congrats to @KarelBrinda et al. Fantastic work :) you know I love compressed data very much!
A decade ago, we had thousands of bacterial genomes. Now, we have millions. How to scale computational methods? Our paper in @naturemethods answers this: use evolutionary history to guide compression and search. …From terabytes to tens of GBs… w/@Baym @ZaminIqbal et al. 🧵1/
SEA 2025 is going to be in beautiful Venice, 22-24 July. List of accepted papers is here regindex.github.io/sea2025.github…. Come and join us! And congratulations to all authors for their insightful contributions!
Great opportunity here with a great mentor!
We are hiring PhD students in Computational Mathematics and Mathematics at Stockholm University in various subjects: su.varbi.com/en/what:job/jo… Application deadline: April 22 (1/3)
On my way back home after DSB in Pisa. It’s been a killer edition! I have been really impressed by the high quality of the presentations. Congratulations to all the speakers again! Next year, DSB is going to be in Venice (in early March)! Don’t miss it 😉
What a killer program for DSB '25 in Pisa! Can't wait to meet you there next week! dsb-meeting.github.io/DSB2025/
PtrHash MPHF has a DOI, At last! 1.5y after starting the project. - 2.4bits/key - 1.75x faster lookup than PTHash&PHOBIC for string keys (44ns) - 12ns per query for 1e9 int keys - 8ns with streaming; basically saturating RAM bandwidth (limit is 7.5ns). arxiv.org/abs/2502.15539
Can't wait to use it for Fulgor :)
