Teaching Assistant for the courses of Advanced Calculus, Linear Algebra and Differential Equations (undergraduate level) from Fall 1984 to Spring 1986.

At Brown Univ.

Teaching Assistant for the course of Statistics (advanced undergraduate/graduate level) in Fall 1988, Fall 1989 and Hilbert Spaces (graduate level) in Fall 1990.

At the American College of Thessaloniki

1993-1999: As assistant professor of mathematics, I have taught Precalculus, Calculus, Statistics and Game Theory.

At Aristotle Univ.

1987-1988: In the framework of the EC Erasmus Project, I taught a course on Optimal Control Theory

2000-Now: I have taught Calculus, Linear Algebra, Ordinary Differential Equations, Partial Differential Equations and Complex Variables. Also participated in teaching the post-graduate course Machine Learning.

 COMPUTER EXPERIENCE

I am interested in both theoretical aspects of computer science and practical applications of computers. In the period 1996-2000 I have planned and supervised a number of initiatives ranging from the scheduling of the use of computer resources to the development of academic software. In the period 2001-2003 I have worked on the use of the Mathematica and Maple computer algebra packages for the teaching of mathematics. Since 2008 I have been developing a number of pursuit / evasion applications involving both computational and animation aspects.

Software Projects

The following list includes some of the applications which I have developed.

  1. Installation and organization of the speech processing complex (software and hardware), Division of Applied Mathematics, Brown University, Providence, RI, USA. 1988-1990.
  2. Database development (personnel, materiel), Informatics Section, VI Division Headquarters, Greek Armed Forces. 1992.
  3. Installation of various software packages (MATLAB, ACSL, MEDAL, MUME, MATCALC) on the workstations of the Robotics Lab of the Department of Electrical and Computer Engineering, Aristotle University.
  4. Desktop Publishing of the Journal of Liberal Arts, the ACT academic journal.
  5. Development of WEB pages for Aristotle University.
  6. Development of software packages for time series classification and prediction, using algorithms I have developed in collaboration with professor Vassilios Petridis.
