# Andrei Martinez-Finkelshtein

##### Education

B.S. and M.A. in Mathematics (1986), Havana University, Cuba

Ph. D. in Mathematics (1991) State Moscow University "M.V. Lomonosov", Russia

##### Biography

Dr. Martinez-Finkelshtein started teaching full time at Baylor in January 2018. Before joining Baylor University, Andrei was full professor of applied mathematics at the University of Almeria, Spain (1994-), an affiliation he still keeps. He also taught at the Havana University, Cuba (1991-1994) and held visiting positions at several universities in Spain (Universidad Autonoma de Madrid, and Universidad Carlos III de Madrid) and the United States (University of South Florida and Vanderbilt University). He is member of several professional societies, and currently, Program Director of the SIAM Activity Group "Orthogonal Polynomials and Special Functions" (its vice-chair in 2017-2019). He is also in the editorial board of four journals. He loves gadgets, and his hobbies include listening to music, reading, swimming, and meeting friends.

##### Academic Interests and Research

Dr. Martinez-Finkelshtein's research areas include approximation theory, orthogonal polynomials, special functions and applications, Riemann-Hilbert problems and asymptotic analysis, complex and numerical analysis, and mathematical modelling, in particular, in ophthalmology and vision science.
