The reason why the sky is blue is #quantum. The reason why it is sometimes pink is sunsets. #theochem #xai #qubits #quovadis

Wonderful hosting Ruben Van der Stichelen again in the QuNB lab during a quick hop from his @fwovlaanderen.bsky.social long stay abroad at the Izmaylov lab at UofT. Quantum chemistry in the age of NISQ and the seniority quantum number. (1/2)

Wonderful lecture by Dr. Tomoya Shiota from Osaka University to the QuNB group. Impressive progress on how to combine #compchem data from seemingly disjoint datasets (inorganic vs organic) and how to make them work together in a transparent ML framework. (1/2)

Huge congrats to soon-to-be Dr. Amir Ayati for successfully defending his PhD thesis earlier today! Beautiful finale of 4+ years of collaborative work on (re-)intruding spin-breaking and restoration methods in quantum chemistry! 👏🎉 (1/2)

Delighted to have Mohammad Ahmadpoor from Augusto Gerolin’s lab @uottawa.ca over to optimally navigate us through (quantum) optimal transport! “Interesting things happen at the borders -transitions- not in the middle where everything is the same” — #nealstephenson #math&chem

Special shoutout to Carla Carvajal, Rebecca Mulder and Dowa Fatima for defending the QuNB colors with their work on protein simulations and mutual information indices! And obviously also Mostafa Javaheri for mentoring these bright youngsters through the term! #ProudPI #compchem

No QuNB meeting presentation today bc we had Lexin Ding (formerly LMU, now ETHZ) presenting their recent work on Maximally Engangled Atomic Orbitals (MEAO) yesterday arxiv.org/abs/2501.15699. Strong recommend (if not only for introducing the being the best acronym of 2025 🐱)!

Big congrats to QuNB group member Amer El-Samman for successfully defending his PhD thesis on #InterpretableML for #chemsky! Amer's work undeniablly set the tone for the next years in the lab re: #ML4Chem. Awesome scientist, great communicator, check it out aichemist.ca #ProudPI #compchem (1/2)

I always loved this picture of Kris (right) with my other mentor David Rowe (left), undoubtedly adding nuance during a workshop seminar at the Institute for Nuclear Theory in 2007. (3/3)
