About Me

I am a PhD Student at Imperial College London in the Large-scale Data and Systems (LSDS) group, and a member of the Imperial College Centre for Cryptocurrency Research and Engineering (IC3RE). I'm also the primary author and lead for the Teechain Network, a secure high-performance off-chain payment network for blockchains.

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.

“No one lights a lamp and puts it in a place where it will be hidden, or under a bowl. Instead they put it on its stand, so that those who come in may see the light.” Luke 11:33
