About me

Optimal Control Theory and Applications
Optimization Theory and Applications
Numerical Analysis
Numerical Methods

My research encompasses optimization, optimal control and numerical analysis, and is concerned with devising numerical techniques and algorithms. Currently, it revolves around

Discretized Solutions of Optimal Control Problems
Duality for Optimization and Optimal Control
Multi-objective Optimization and Optimal Control
Optimal Path Planning, Numerical Analysis and related areas

During the time I have been with UniSA, I also held visiting positions as: CAPES Foreign Visiting Prof at Federal Uni of Rio de Janeiro (Brazil, 12 months), Assoc Prof at Bilkent Uni (Turkey, 6 months), and Visiting Prof for shorter terms (1 to 3 months) at Uni of Muenster (Germany), Uni of Vienna and Tech Uni of Vienna (Austria), Middle East...
