Research Interests:

My research area includes ordinary differential equations, fractional differential equations, calculus of variation and optimal control. I focus on the qualitative study of some classes of evolution equations, applicable in many scientific fields such as physics and biology. I am also interested in determining the control signals that could allow a process to satisfy physical constraints while minimizing (or maximizing) some performance criterion.
