    With this announcement out, it's time for an overdue career update! I’ll be joining Harvard SEAS in 2023. I’m beyond thrilled to be part of this superb cohort of incoming faculty, and to join such an exciting, forward-looking and interdisciplinary academic unit as @hseas. [1/n]
    It's been an exciting year for faculty hiring at Harvard CS: We've recruited 7 faculty members who all have Twitter accounts! Looking forward to welcoming @ShamKakade6, @AnuragAnshu4, @elmelis, @jefrankle, @sitanch, @YannaiGonch, @viegasf. seas.harvard.edu/news/2021/10/s…

    New paper (w/ @nfusi) #ICML2021: “Dataset Dynamics via Gradient Flows in Probability Space” TL; DR: we cast transfer learning, dataset ‘shaping’ and model re-purposing as *labeled* dataset optimization using gradient flows in the "space of datasets" Longer version: a🧵

    Exactly 10 years ago this day, I arrived in the US with my entire life packed into two suitcases for what was supposed to be just a masters’ degree “and then I’ll head back home” 😅

    Happening today! Join us in room 220-222 for a day packed with Optimal Transport, from theory to applications, w/ talks by Felix Otto, Laetitia Chapel @RFlamary @brandonamos @ArnaudDoucet1 Florentina Bunea, Smita Krishnaswamy, Sinho Chewi among others! #FeelTheMonge #NeurIPS2023
    🚀 #OTML is back for this year’s NeurIPS! We'll have a superb set of speakers (TBA soon) spanning theory, stats, and comp aspects of OT. If you're looking for a home for your work on OT or related topics, we'd love to see it (link to CFP below). Deadline: Sep 29th. #Monge

    It’s official! 👩🏻‍🎓Dr Amores it is. Extremely proud of @jdthamores for a spectacular PhD defense. A fitting testament to a remarkably interdisciplinary researcher, her thesis seamlessly weaves together science, art and design. She never ceases to amaze me, and did so again today 🎉

    A propos of #NeurIPS2022 rebuttals, I asked DALL-E to help me visualize Reviewer #2 reviewing our paper. Did not disappoint.

    This has been a few months in the making, so very happy to finally see it go live! 🎆 The blog gives an overview of our paper (w/ @nfusi) on OT dataset distances (+ fun interactive visualizations). The context: we're interested in a notion of distance between datasets... (1/n)
    Microsoft researchers propose Optimal Transport Dataset Distance, a method for computing similarity b/w labeled datasets—regardless of whether their label sets are directly comparable. Learn how it can predict task transferability & help data augmentation: aka.ms/AA9p00v

    Some things sound too good to be true. This is *not* one of them. Been here only a few weeks, but can safely say it’s as great as this listing makes it sound - awesome collaborators, exciting environment, freedom in shaping research agenda, i.e., postdoc paradise. Apply!
