We did not domesticate wheat. It domesticated us. - Yuval Noah Harari.

Hello. I am Sazzadur Rahaman

PhD Candidate • Security Enthusiast

I am a PhD candidate in Computer Science Department @VT, working under the supervision of Dr. Danfeng (Daphne) Yao. My research objective is to minimize the gap between theory and the applications of cryptographic schemes for wide adoption.

[Thesis committee: Dr. David Evans, Dr. Naren Ramakrishnan, Dr. Patrick Schaumont, Dr. Gang Wang, Dr. Danfeng (Daphne) Yao (Chair).]

Before moving in Blacksburg, I worked as a software engineer. I have 3+ years of industry experience in OOP, AOP and soul JavaEE technologies, smart card and payment based solutions. Founding member and initiator of JUG BD (Java User Group, Bangladesh. Speaker in JavaOne-2015, JUG BD Meetup (3.0 & 5.0). I completed my under graduation from BUET. I am greatly indebted to my undergrad thesis supervisor, Dr. Md. Saidur Rahman for his guidance, support and inspiration.
