My name is Hung. I was born in 1980, Hai Phong city (Vietnam). In 1997 I graduated high school and at that same year, I started as a math student at Hanoi National University of Education. I obtained my MSc degrees from that university in 2003. In 2013, I received my Ph.D. from Institute of Mathematics, Vietnam Academy of Science and Technology, under the supervision of Professor Nguyen Minh Chuong. From 2002 up to now I am a Lecturer at High School for Gifted Students, Hanoi National University of Education. I am very interested in teaching High school Mathematics and training Math Olympiad problems. From 2007 up to now, I was invited to give lectures to the IMO Training Camp for Vietnamese team. From 2010-2014, I am the Math Olympiad Head teacher at High School for Gifted Students, Hanoi National University of Education. My current research interests are in studying the following: Hardy’s inequalities, boundedness of classical operators on functional spaces, theory of Hardy spaces, real and complex Harmonic Analysis.
