Marie S.-Curie Actions: SPICES

Funded by Marie Skłodowska-Curie Actions (MSCA) as an European Fellow from 2023 June to 2025 May, I am currently leading the Statistics-driven Planet Imaging in Circumstellar Environments (SPICES) 🔗 project on

Understanding the formation mechanism of spiral arms in protoplanetary disks. See "Spiral Arms & 'Missing' Planets" page's SAFFRON project.
