Titu Andreescu received his BA, MS, and PhD from the West University of Timisoara, Romania. The topic of his doctoral dissertation was "Research on Diophantine Analysis and Applications." Professor Andreescu currently teaches at the University of Texas at Dallas. Titu is past chairman of the USA Mathematical Olympiad, served as director of the MAA American Mathematics Competitions (19982003), coach of the USA International Mathematical Olympiad Team (IMO) for 10 years (19932002), director of the Mathematical Olympiad Summer Program (19952002), and leader of the USA IMO Team (19952002). In 2002 Titu was elected member of the IMO Advisory Board, the governing body of the world's most prestigious mathematics competition. Titu is also co-founder and director of the AwesomeMath Summer Program (AMSP). Titu received the Edyth May Sliffe Award for Distinguished High School Mathematics Teaching from the MAA in 1994 and a "Certificate of Appreciation" from the president of the MAA in 1995 for his outstanding service as coach of the Mathematical Olympiad Summer Program in preparing the US team for its perfect performance in Hong Kong at the 1994 IMO. Titus contributions to numerous textbooks and problem books are recognized worldwide.Dorin Andrica received his PhD in 1992 from Babes-Bolyai University in Cluj-Napoca, Romania, with a thesis on critical points and applications to the geometry of differentiable submanifolds. Professor Andrica has been chairman of the Department of Geometry at Babes-Bolyai" since 1995.
