I am a Ph.D. candidate in the College of Information and Computer Sciences at the University of Massachusetts Amherst under the supervision of Subhransu Maji in the Computer Vision Lab. Previously, I spent three years as a graduate research assistant under the supervision of Pablo Arbeláez in the Biomedical Computer Vision Group at the Universidad de Los Andes, where I got my Master's degree in Biomedical Engineering. I got my Bachelor's degree in Electronics Engineering from Universidad del Norte in Barranquilla, Colombia.
From data to science with AI and human-in-the-loop→go to research
My research in computer vision and machine learning focuses on finding effective ways to combine human and computational effort, and statistical estimation to reduce the cost of deriving scientific outcomes. My work focuses on analyzing data from novel scientific domains where data collection and labeling are expensive and require expertise.
My work is also interdisciplinary, where I collaborate with ecologists to study phenology and population declines on bird species using RADAR imagery→(project page), with astronomers to provide insights into the process of star formation and the birth and evolution of galaxies from the Hubble Space Telescope (HST) and the James Webb Space Telescope (JWST) data→(project page), and with chemists to predict absorption of nanoporous materials→(project page). My research goal is to create data-efficient solutions to enable fundamental scientific advances and the understanding of the world and the universe to help improve our lives.
Here is my research statement, CV, and a list with my publications.
I'm also a photography enthusiast. → Some of my photos .
