Aigerim Kalybay is an Associate Professor at the Department of Economics. After graduating from L.N. Gumilyov Eurasian National University in 1998 she received a research fellow position at the Institute of Mathematics of the Academy of Sciences of the Republic of Kazakhstan. She worked at the Institute of Mathematics for six years, during which in 2002 she attained the degree of Candidate in Physical and Mathematical Sciences. In 2004 she received a grant from the Royal Swedish Academy of Sciences for a two-year postgraduate study at the Luleå University of Technology, where she defended her PhD Thesis in 2006. In the same year she joined KIMEP.
