معرفی
Theodoula N. Grapsa is an Associate Professor in the Department of Mathematics at the University of Patras, Greece. She is affiliated with the Division of Computational Mathematics and Informatics within the department. Her office is located at B/M 243, and she can be reached at grapsa@math.upatras.gr or theodoula.grapsa@gmail.com.
Dr. Grapsa's research focuses on several key areas in computational mathematics:
- Numerical Analysis and Optimization Methods
- Systems of Nonlinear Equations
- Interval Analysis and Global Optimization
- Neural Networks and Machine Learning Algorithms
- Computational Mathematics and Numerical Algorithms
Her recent work shows a strong emphasis on developing and improving optimization algorithms, particularly for unconstrained optimization problems. She has made significant contributions to Newton's method modifications, conjugate gradient approaches, and hybrid techniques that combine forecasting with optimization. Her research bridges theoretical mathematics with practical computational applications, particularly in the areas of neural network training and solving complex nonlinear systems.
Dr. Grapsa has supervised numerous graduate students throughout her career, including PhD candidates and MSc students. Her past PhD students include Dimitris G. Sotiropoulos, John A. Nikas, and Aristotelis E. Kostopoulos. Current PhD students under her supervision are Eleftheria N. Malihoutsaki, Athanasia N. Papanikolaou, and Christina D. Nikolakakou.
She has authored two books:
- "Εισαγωγή στην Ανάλυση Διαστημάτων - Interval Analysis" (2012)
- "Προγραμματίζοντας με Fortran'90" (2012)
Dr. Grapsa is actively involved in teaching, including the course "Basic Principles of Programming," for which she organized an educational visit to the Patras Science Centre in Rio for first-year mathematics students in April 2013.
