Personal profile
Research profile
Astrid is enrolled in the 5 years Ph.D. program in the Signal Processing Systems group as a member of the Information and Communication Theory Lab. Her research focuses on mathematical modeling for optical fiber transmissions in the nonlinear regime, and the design of pragmatic digital signal processing schemes to overcome nonlinear distortions.
Academic background
Astrid holds a B.Sc. (2012) and M.Sc. (2018) degrees in Physics from Universidad del Valle, Colombia. Her MSc research focused on the efficiency of surface codes, a family of topological quantum error-correcting codes.
During 2017 and 2018, she worked as an assistant professor at Universidad del Valle and the Pontifical Xavierian University. Due to her type Ph.D., she is actively engaged in training and practice activities in education.
