Short Bio

    I am a Computer Science PhD candidate at Purdue University specializing in Computer Security and Cryptography, advised by Professor Jeremiah Blocki. My research focuses on privacy-preserving systems, cryptographic protocols, secure systems, and the theoretical foundations of computer security. My research interests include applied cryptography, Conditional Encryption, memory-hard functions, cryptocurrency and blockchain security, obfuscation, secure cloud computing, searchable encryption, and provable security. More broadly, I am interested in the design and analysis of trustworthy computing systems, especially systems that require strong privacy and security guarantees under rigorous adversarial models. My work combines formal modeling, security analysis, technical writing, and research communication. I am especially interested in questions at the intersection of cryptography, privacy, security protocols, and real-world systems, including both foundational research and applied security problems. I am also interested in the practical implementation and evaluation of secure cryptographic algorithms for real-world applications.
