Bio: Sachit Butail is an Assistant Professor of Mechanical Engineering at Northern Illinois University, where he directs the Emergent and Autonomous Systems Lab. He received his Ph.D. in 2012 in Aerospace Engineering from University of Maryland, College park, where his dissertation was on the three-dimensional motion reconstruction of animal groups. Following that, he was a postdoctoral fellow in Mechanical and Aerospace Engineering at New York University for a few years where he worked on problems in collective behaviour and animal-robot interactions using methods from machine learning, time-series analysis, and information theory. Butail's research interests are in the areas of dynamical systems, collective behaviour, robotics, and bioinspired autonomy. He teaches courses in vibrations, modeling complex systems, and robot vision and control. Butail has authored nearly 40 peer-reviewed publications including some in high impact interdisciplinary venues. His research has been supported by the National Science Foundation.
