Dr. Andrei V. Olifer believes that understanding the brain is one of the greatest scientific puzzles, and mathematical modeling is essential in solving this puzzle. He got his bachelor's degree in applied mathematics and Ph.D. in applied mathematics and mathematical physics in Russia. In his early career, he held visiting research positions in Pushchino (Russian Academy of Sciences), Budapest (Hungarian Academy of Sciences) and Paris (Pasteur Institute). From 2000 to 2004 he worked on mathematical modeling of hippocampal neurons in the Czech Academy of Sciences in Prague. From 2004 to 2011, Olifer held a research position at Emory University, Atlanta. At Emory, he learned how to record neuronal activity and process raw experimental data. He also taught several classes including the course “Mathematical Concepts in the Neurosciences” that he developed himself. The work on that course was funded by a Howard Hughes Medical Institute grant. 

In 2011, Olifer joined Georgia Gwinnett College faculty. In the classroom, he tries to show students the essence, practical utility, and beauty of mathematics. Olifer helps students develop active learning skills. He is certain that active learning, driven by the student’s own curiosity, is the best way to learn. Olifer regularly offers projects for undergraduate research.
