About Me

I am currently a Founding Engineer at Aptos Labs, working on layer 1 blockchain technology. Before this, I was a Research Scientist working at Novi (Meta/Facebook) on the Diem blockchain (formerly Libra). I completed my PhD at Imperial College London in the Large-scale Data and Systems (LSDS) group and the 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 PhD focused on improving the security and privacy of large-scale distributed systems using trusted hardware. Most recently, I have focused on improving the security, privacy and performance of blockchains and cryptocurrencies.

“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 NIV
