Dr. Juan José Moreno Balcázar is a Professor in the Mathematics Department at the University of Almería (UAL), Spain. He leads the research group 'Teoría aproximación y polinomios ortogonales' (Approximation Theory and Orthogonal Polynomials) and has served as Principal Investigator for numerous research projects funded by Spanish national and regional agencies from 2002 through 2025. His primary research interests include Orthogonal Polynomials (particularly Sobolev orthogonal polynomials), Approximation Theory, Special Functions, and Asymptotic Analysis. His work spans theoretical developments in q-hypergeometric polynomials, difference equations for orthogonal polynomials, and applications in mathematical physics. He has also contributed to interdisciplinary areas including mathematics education, epidemiological modeling, and gender studies in science. Professor Moreno Balcázar maintains an active publication record with 68 articles, 14 books or book chapters, and 4 theses. His recent work shows continued productivity with publications in 2024, 2023, and 2022 in journals including PHYSICA SCRIPTA, Journal of Approximation Theory, and Results in Mathematics. His research demonstrates strong theoretical foundations with applications across mathematics and related fields. He has supervised multiple doctoral students and maintains collaborations with researchers across Spain and internationally, particularly in Ecuador and Brazil. His work spans both pure mathematical theory and practical applications in education and public health.
