Nairi Sedrakyan (born 1961 in Ninotsminda, USSR) is an Armenian mathematician involved in national and international Olympiads of mathematics, having been the president of the Armenian Mathematics Olympiads, the Leader of Armenian IMO Team,[1] a jury member and problem selection committee member of the International Mathematical Olympiad,[2] a jury member and problem selection committee member of the Zhautykov International Mathematical Olympiad (IZhO),[3] a jury member and problem selection committee member of the International Olympiad of Metropolises,[4] the president of the International Mathematical Olympiad Tournament of the Towns. He has also authored a large number of problems proposed in these Olympiads. The government of Armenia awarded the author the title of the best teacher of Armenia and he received a special gift from the Prime Minister.[5] Nairi Sedrakyan's son Hayk Sedrakyan is also a professional mathematician and former IMO competitor.[6][7]

Nairi Sedrakyan has authored 14 books and around 70 articles in different countries (USA, Switzerland, South Korea, Russia) on the topic of problem solving and Olympiad style mathematics. [11][12]

Early life and education

Nairi Sedrakyan was born in the USSR in the town of Ninotsminda in the Georgian SSR. At the age of 14 years old he left Ninotsminda for Yerevan, Armenian SSR to advance his mathematical knowledge and to study mathematics at the PhysMath School after A. Shahinyan (Yerevan), one of the leading schools in Armenia. He continued his Bachelor, Master and PhD studies at the Yerevan State University in the faculty of Mathematics and Mechanics, widely regarded by students as one of the toughest faculties in the university.[5]

Mathematics coaching and Olympiads

The students of Nairi Sedrakyan have obtained 20 medals (1 gold medal, 4 silver medals, 15 bronze medals, one of which was received by his son Hayk Sedrakyan) in the International Mathematical Olympiad, providing more than half of the medals that Armenia received in the history of its participation in the International Mathematical Olympiad. So far it is the single Gold Medal of Armenia in the International Mathematical Olympiad.[13]
