Biography

Naira Hovakimyan received her MS degree in Theoretical Mechanics and Applied Mathematics in 1988 from Yerevan State University in Armenia. She got her Ph.D. in Physics and Mathematics in 1992, in Moscow, from the Institute of Applied Mathematics of Russian Academy of Sciences, majoring in optimal control and differential games. Before joining the faculty of UIUC in 2008, she has spent time as a research scientist at Stuttgart University in Germany, at INRIA in France, at Georgia Institute of Technology, and she was on faculty of Aerospace and Ocean engineering of Virginia Tech during 2003-2008. She is currently W. Grafton and Lillian B. Wilkins Professor of Mechanical Science and Engineering at UIUC. In 2015 she was named as inaugural director for Intelligent Robotics Lab of CSL at UIUC. She has co-authored two books and more than 300 refereed publications. She is the recipient of the SICE International scholarship for the best paper of a young investigator in the VII ISDG Symposium (Japan, 1996), the 2011 recipient of AIAA Mechanics and Control of Flight award and the 2015 recipient of SWE Achievement Award. In 2014 she was awarded the Humboldt prize for her lifetime achievements and was recognized as Hans Fischer senior fellow of Technical University of Munich. In 2015 she was recognized by UIUC Engineering Council award for Excellence in Advising. She is a fellow and life member of AIAA, a Senior Member of IEEE, and a member of SIAM, AMS, SWE, ASME and ISDG. Naira is co-founder and Chief Scientist of IntelinAir. Her work in robotics for elderly care was featured in the New York Times, on Fox TV and CNBC.
