Ehsan Shahamatnia is a PhD candidate of the
Electrical and Computer Engineering program (DEEC) at Universidade
Nova de Lisboa. He received a BSc. degree in software engineering
and a MSc. degree in artificial intelligence and robotics in 2006
and 2010 respectively. His Master's thesis topic involved development
of a hybrid swarm intelligence system for computer vision and tracking
deformable objects. He is currently a researcher at CA3-Computational
Intelligence Research Group of UNINOVA, where he participates in applied
research and development projects to create solutions for real-world
problems mainly from space domain. His main focus for doctoral studies
is developing a framework for processing solar images and analyzing
solar features and proposing a tool for solar feature characterization
and tracking.
