Luis Roberto Mercado Diaz is a Ph.D. student in Biomedical Engineering at the University of Connecticut, where he is advancing the frontiers of neurodiagnostics by combining biomedical data with cutting-edge computational methods. Under the mentorship of Dr. Hugo F. Posada Quintero, Luis is applying machine learning and graph signal processing techniques to enhance the early detection of complex neurological conditions, including Normal Pressure Hydrocephalus (NPH), Autism Spectrum Disorder (ASD), and ADHD. His current work involves analyzing MRI and electroretinogram (ERG) data to identify subtle biomarkers that traditional imaging methods often miss.

Before UConn, Luis cultivated a remarkable career across several roles in data science and technology consulting in Colombia, supporting major clients such as SAS, Bancolombia, and Scotiabank. He designed predictive models, led cloud-based big data projects, facilitated technical workshops, and deployed machine learning solutions across public and private sectors. His experience spans startups, government projects, and corporate consulting, underlining his versatility and drive to make impact through innovation.

Driven by a desire to fuse his technical knowledge with meaningful, real-world applications, Luis pursued graduate study at UConn—attracted by its vibrant research community and interdisciplinary focus. At UConn, he received the IBACS Research Fellowship for 2025–2026 and presented his work at the ACII 2023 and BSN 2024 conferences, supported in part by the JLLA Travel Award.

As part of the John Lof Leadership Academy (JLLA), Luis serves on the Social Media Committee, contributing to the Academy’s digital presence through strategic communications and compelling visual content. He values JLLA as a structured platform where leadership theory meets practice. “JLLA helped me build the confidence to take initiative, lead more effectively in the lab, and collaborate across disciplines,” he reflects.

Luis encourages fellow students to engage deeply with the processes they encounter—whether in research, class, or student leadership. “Don’t just participate—seek to understand and improve. That’s where leadership begins.”

Looking ahead, Luis envisions a career where he bridges advanced computational research with biomedical innovation, ultimately working to improve the lives of patients through more accurate and accessible diagnostics.
