I'm currently a post-doctoral researcher in the Large-Scale Distributed Systems (LSDS) group of the Department of Computing, Imperial College London. Prior to joining Imperial I was a software engineer in the financial services industry building stream processing platforms for high-frequency trading. Before that I was a member of the OPERA group at the University of Cambridge Computer Laboratory, where I completed my PhD under Prof. Jean Bacon.
