Dr. Alejandro Lopez Valdes
Assistant Professor, Electronic & Elect. Engineering

Biography

Currently, an Assistant Professor in Neural Engineering and Brain Health affiliated to the School of Engineering and The Global Brain Health Institute. I strive to contribute to the creation of applicable and scalable methods and solutions to support brain health throughout the lifespan. My research focuses on applied neural engineering supporting, aging, sensory dysfunction and cognition.

Born in Mexico in 1987, I have a background in biomedical engineering, and specialized in neural engineering. I have industry experience in the fields of ophthalmology surgery medical device service and management, medical device design, and auditory assistive devices research and development.

I obtained a Bachelor's Degree in Biomedical Engineering from ITESM in Monterrey, Mexico. Completed my Master's of Science in Bioengineering from the University of Groningen and Trinity College Dublin through the CEMACUBE programme funded by the European Union. I hold a PhD in Mechanical and Manufacturing Engineering, specialized in neural engineering, from Trinity College Dublin.

Before joining Trinity College Dublin as faculty, I carried out research in the area of cognitive hearing sciences and brain hearing technologies at Eriksholm Research Centre in Denmark.

Research Expertise

Description

My research interests focus on applied neural engineering supporting, aging, sensory dysfunction and cognition. Aiming to help better understand changes in brain health as individuals move through their life. By including contextual information to capture the nuances of individual lifestyles and allow for individualized approaches to brain health. This would facilitate early detection of cognition difficulties before they become acute and support a healthy brain ageing.
