Summary
I am a Professor of Distributed Systems in the Department of Computing at Imperial College London. I lead the Large-Scale Data & Systems (LSDS) group that does research on scalable data-intensive secure software systems of any kind. I am also the Co-Director (Research) for Imperial's I-X initiative in artificial Intelligence, machine learning and data science, and I serve as the Director of Research in the Department of Computing.
Before joining Imperial, I was a post-doctoral researcher in the Systems Research group at Harvard University. I received my M.A. and Ph.D. degrees from the University of Cambridge.
