Biography
Abubakr does fundamental research at the interface of engineering, applied mathematics and physics, on various problems in robotics, distributed sensing, network dynamics and quantum information sciences. His interests span the study of connections and complexity in large-scale distributed networks; topological methods for information discovery in massive data sets; and communication, computation & control issues in the physics of information. He has also worked and consulted for the industry on the design of air traffic control systems, radar & sonar systems, communication equipments and medical instrumentation.
Abubakr received his PhD in Electrical Engineering from Georgia Institute of Technology (2005). As a graduate student, he also got a masters degree in Mathematics (2005) and a masters degree in Electrical Engineering (2002) from Georgia Tech. He completed his BSc in Electrical Engineering from the University of Engineering and Technology Lahore, Pakistan (2000). Before joining LUMS, he has taught and done research as a postdoctoral fellow at McGill University, Canada (2007-2008) and at the University of Pennsylvania, USA (2006-2007).
