Join us in welcoming the first cohort of Delta Fellows! 🎉 Congrats to the ~100 amazing researchers and engineers joining the Delta Institute family. We're excited for our fellows to get to know each other through dinners, retreats, and much more! Our fellows come from diverse backgrounds: undergrads, PhD students, high-frequency trading, big tech, startups, neolabs, frontier labs, and more. What brings them together is their kindness, intellectual curiosity, and intrinsic passion for their field. deltainstitutes.org/cohort1
