Alexandre Bernardino

Welcome to my wiki page. I've definitely moved to mediawiki, given its editing facilities. My old web page is no longer being updated.

---

I'm an Assistant Professor at the Dept. of Electrical and Computer Engineering of the Faculty of Engineering at IST, the Faculty of Engineering in the Technical University of Lisbon. Also, I'm a researcher at ISR-Lisboa, the Institute for Systems and Robotics, and co-coordinator of VisLab, the Computer and Robot Vision Laboratory.

Research

My main research interests focus on the application of computer vision, cognitive science and control theory to advanced robotic and surveillance systems. Currently I'm involved in projects involving Humanoid Robots (Visual Attention, Foveal Vision, Model Based Tracking, Learning Affordances, Sensorimotor Coordination) and Surveillance Systems (Target Detection, Tracking and Identification, Human Activity Recognition).

Contact me if you are interested in working in some of these topics.
