I graduated from the Faculty of Mathematics of the Sofia University "St. Kliment Ohridski" in 1970. I defended my PhD Thesis on the topic: Synthesis of slot aerial grids with Hausdorff type directive patterns, Department of Radio-Electronics, VMEI, Sofia, 1979. From 1970 to 2010 I worked at the Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences. From 2010 to this moment I have been working as a professor and guest professor at the Faculty of Mathematics and Informatics at the Paisii Hilendarski University of Plovdiv. I am an associate member of the Mathematical Modeling and Numerical Analysis Section at the Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences. I am the author/co-author of 400 publications and 30 monographs. Some of them have been published in: Compt. rend. Acad. bulg. Sci., Z. Angew. Math. Mech., BIT, Computing, J. of Comput. and Appl. Math., Computers and Math. with Applic., Comput. Math. and Math. Phys., Japan Journal of Industrial and Applied Mathematics, J. Math. Chem and journals from the MDPI series, as well as in the publishing houses: Elsevier Science Publ.; WILEY-VCH Verlag Berlin GmbH. My main interests are in the following areas: numerical methods for solving nonlinear problems; approximation theory; dynamic analysis and chaos in differential models; reaction-kinetic models; biochemical oscillators and control (approximation and optimization) over oscillations.
