I am a researcher in cryptography. I work as a senior researcher in a blockchain startup Cryptape. I was an associate research fellow and a lecturer in mathematics from 2019 to 2021. I received my Ph.D in cryptography under the supervision of Prof. dr. ir. Vincent Rijmen, from COSIC KU Leuven, Belgium in 2018. My Ph.D thesis is Techniques for Block Cipher Cryptanalysis.

My main focus is on the security evaluation of lightweight ciphers with rotational cryptanalysis, linear cryptanalysis, etc, as well as using mathematics to improve our understanding of distinguishers.

• Mathematical theory of cryptanalysis
• New methods to build distinguishers
• Automated cryptanalysis with constraint programming (SAT/SMT/MILP)

I work on the protocol design of payment channel networks in blockchain ecosystems.

• Payment channels with improved features, e.g., constant collateral, value privacy, rebalancing
• Applications of cryptographic primitives in blockchain technology
