Research
Renata is a co-author on euler-99's substrate-integrated planning work. Her contributions centre on the rollout-and-replan loop that lets a substrate-hosted agent maintain a plan across calendar weeks while the underlying environment shifts.
She has been with alphabell since 2021 and is based in Bogotá. She is one of the lab's primary contacts for Latin American academic groups.
Background
Ph.D. computer science, Universidad de los Andes (Bogotá), 2015.
Prior to alphabell: Los Andes; Praxis AI Studies; Hyperion Cognitive Lab.
