About Me

I am a PhD Student at Imperial College London in the Large-scale Data and Systems (LSDS) group. I'm also the primary author and lead for the Teechain Network: Teechain.Network.

Under Prof. Peter Pietzuch my research focuses on improving the security and privacy of large-scale distributed systems. Most recently, I have focused on improving the security of cloud infrastructures and peer-to-peer networks, such as blockchains and cryptocurrencies, through the use of trusted hardware.
