I am a PhD candidate in the Systems Research Group at the Cambridge University Computer Laboratory, supervised by Anil Madhavapeddy and Jon Crowcroft. I am interested in systems, security, virtualization, and trustworthy computing. My research focuses on providing strong isolation, effective privilege separation, and secure sharing mechanisms to protect applications in the edge-cloud environment. I am currently building a lightweight SW/HW stack, including OS abstractions, for full-system threat analysis and pervasive compartmentalization across privilege boundaries.

If you are interested in collaboration or doing an internship with us, see our current projects and ping me .

  • I love reading good books, travelling, playing guitar, walking while listening to audio books or good music, and I do love amazingly beautiful Cambridge.
  • Seeing children suffering from cancer is one of the saddest things ever, maybe even our small support help them in their fight a little bit (e.g., MAHAK ).
