Summary
I'm a PhD student at the Imperial College London Centre for Cryptocurrency Research and Engineering. My research focuses on trustless and scalable cross-chain communication protocols under the supervision of Professor William Knottenbelt and Dr Arthur Gervais.
My general research interests revolve around security, interoperability and decentralization of cryptocurrencies. My latest work covered topics, such as:
- Trustless cross-chain communication via cryptocurrency-backed assets
- Efficient, crowdfunded, cross-chain bribing attacks
- Security of decentralized mining pools
