The School of Cybersecurity and Privacy at Georgia Tech is proud to recognize the accomplishments of five doctoral students who finished their doctoral programs in Spring 2025. These scholars have advanced critical research in software security, cryptography, and privacy, collectively publishing 34 papers, most of which appear in top-tier venues.

Ammar Askar developed new tools for software security in multi-language systems, including a concolic execution engine powered by large language models. He highlighted DEFCON 2021, which he attended with the Systems Software and Security Lab (SSLab), as a favorite memory.

Zhengxian He persevered through the pandemic to lead a major project with an industry partner, achieving strong research outcomes. He will be joining Amazon and fondly remembers watching sunsets from the CODA building.

Stanislav Peceny focused on secure multiparty computation (MPC), designing high-performance cryptographic protocols that improve efficiency by up to 1000x. He’s known for his creativity in both research and life, naming avocado trees after famous mathematicians and enjoying research discussions on the CODA rooftop.

Qinge Xie impressed faculty with her adaptability across multiple domains. Her advisor praised her independence and technical range, noting her ability to pivot seamlessly between complex research challenges.

Yibin Yang contributed to the advancement of zero-knowledge proofs and MPC, building toolchains that are faster and more usable than existing systems. His work earned a Distinguished Paper Award at ACM CCS 2023, and he also served as an RSAC Security Scholar. Yang enjoyed teaching and engaging with younger students, especially through events like Math Kangaroo.

Faculty mentors included Regents’ Entrepreneur Mustaque Ahamad, Professors Taesoo Kim and Vladimir Kolesnikov, and Assistant Professor Frank Li, who played vital roles in guiding the graduates’ research journeys.
