Oleg Marichev holds two doctorates in mathematics. His first dissertation, completed at the Belarusian State University, Minsk, was titled "Tricomi's Boundary Value Problem for Some Mixed Type Equations and Integral Equations with Special Functions in the Kernels." His second dissertation, for an advanced doctorate from Friedrich-Schiller-Universität, Jena, Germany, was titled "Functions of Hypergeometric Type and Some Applications to Integral and Differential Equations." Marichev is the author or coauthor of 70 papers and eight books, including his Handbook of Integral Transforms of Higher Transcendental Functions. He wrote the five-volume series Integrals and Series with A. P. Prudnikov and Yu. A. Brychkov. He is also a coauthor with S. G. Samko and A. A. Kilbas of Integrals and Derivatives of Fractional Order and Some of Their Applications, the first complete monograph on the topic. Marichev joined Wolfram Research in 1991 and has developed many of Mathematica's algorithms for the calculation of definite and indefinite integrals and hypergeometric functions including Meijer G.
