I am a postdoctoral researcher at the Institut de Recherche en Informatique de Toulouse IRIT-INP Toulouse, working at the Télécommunications Spatiales et Aéronautiques (TéSA) laboratory (Toulouse, France) under the supervision of Jean-Yves Tourneret.

I got my Ph.D. degree in Computer Science from the Universidad Industrial de Santander, Bucaramanga, Colombia, in 2022. My doctoral thesis "Design and optimization of a compressive spectral video sensing system" was supervised by Henry Arguello and it was a laurated thesis. You can find the thesis here.

I am particularly interested on image and signal processing methods and its applications on practical scenarios.
