Assoc. Prof. Mariyan Milev, PhD

Since 2023, Dr. Mariyan Milev has been an Associate Professor in the Department of Statistics and Econometrics at the Faculty of Economics and Business Administration, Sofia University "St. Kliment Ohridski".

Assoc. Prof. Milev's main scientific interests are in applied mathematics, probabilities and statistics, econometrics, financial derivatives, numerical methods, and fractional equations.

In November 2004, Associate Professor Dr. Mariyan Milev was admitted to the International Doctoral School of Mathematics at the University of Trento, Trento, Italy, after a competition held by the Italian Ministry of Education. In May 2009, he completed a four-year international doctoral program in mathematics with academic advisors Prof. Aldo Tagliani from the Department of Computer Systems and Economic Sciences, Faculty of Economics, and Prof. MD. Luciano Tubaro from the Faculty of Mathematics, Physics, and Natural Sciences at the University of Trento, Italy.

In 2009, Dr. M. Milev, following a competition, joined the program "Methods for Assessing Exotic Options" under a European project as a postdoctoral researcher in economics at the Faculty of Economics, University of Venice, Italy. This included research on the Black-Scholes model, numerical methods for computer modeling and evaluation of financial derivatives, assessment of European and American vanilla and exotic options, and the creation of special numerical algorithms for evaluating discretely observed exotic options with two barriers. Along with other scientists, he applied new methods for option assessment such as radial functions, known as splines in mathematics or neural networks in computer science, to the Black-Scholes equation.

Dr. Mariyan Milev has successively held positions as an Assistant, Chief Assist. Prof., and Assoc. Prof. at Plovdiv University "Paisii Hilendarski" and the UNT- Plovdiv.

He continues to work on international research projects with Prof. Aldo Tagliani from the University of Trento, Italy, Prof. Ahmad Golbabai from Iran University of Science and Technology, Davood Ahmadian from the University of Tabriz, Amir Sobhani from the University of Semnan, and other scholars from Europe, Asia, and America. Most of his scientific publications are indexed in the scientific databases Science Direct, Zentralblatt, Math, Elsevier, Scirus, and MathSciNet of the American Mathematical Society.

Dr. Mariyan Milev is the author of the manual "Application of MATLAB in Economics," edited by Prof. D. Sc. Ivan Ganchev from the Department of Statistics and Econometrics, Sofia University "St. Kliment Ohridski." He is also a co-author of four other manuals on statistics, higher mathematics, and modeling of real processes.

Mariyan Milev is a co-author with Prof. Aldo Tagliani of the book 'Quantitative Methods for Pricing Options with Exotic Characteristics and under Non-standard Hypotheses', 2012, Publishing house: Eudemonia Production Ltd. , Sofia, ISBN: 978-954-92924-1-1.
