I’m a PhD researcher focused on the security of Blockchain and Cryptocurrency. Before academia, I spent 7 years in the military and finished as an army captain, which gave me some disciplined and hands-on experience. Now, I’m working on blockchain security at Tokamak Network, dealing with Layer 2 scalability and security issues. I also travel the world (mostly in Europe), and that really adds some fresh perspectives to my life. Outside of tech, I enjoy conversations about history, philosophy, jazz and science.

Current projects working on:

  • Layer 2 security and cost analysis
  • On-chain distributed randomness
