There is an open call from Fulbright-Colombia for a short-term invitation for a US specialist (2 to 6 weeks). 

Our group MoBiMat located in Cali, Colombia is interested in inviting someone working on mathematical models for pest control.

My university should do the formal application for Fulbright, and I can do the necessary paperwork here. The deadline is November 14, 2024, and you can get more information in English at https://fulbright.edu.co/en/fulbright-u-s-specialist-award-for-institutions/

If someone is interested, please contact me directly.
