Qifan Zhang (张起帆) is now a 4th-year Ph.D. candidate in Department of Electrical Engineering & Computer Science of University of California, Irvine with focus on Computer Security, advised by Prof. Zhou Li. His research interests include Network Security, especially Domain Name System (DNS), and Machine Learning Security and Privacy. Before that, he received his B.Eng. degree in Computer Science and Technology from ShanghaiTech University in 2020, with an interim summer session in University of California, Berkeley in 2017.

Pronunciation of his name: Chee-Fan Jang.
His Curriculum Vitae (last updated on May 25, 2024)

Recent news

  • Domain Name System (DNS). Qifan is interested in security, privacy and reliability of DNS. In particular, he is interested in automated vulnerability detection with fuzzing techniques [Security'24]. Based on his automated tool, ResolverFuzz, several vital vulnerabilities have been discovered, including protocol security [NDSS'23], implementation assessment [Security'23], etc.
  • Machine Learning Security and Privacy. Qifan is also interested in security and privacy topics related to machine learning. His past research demonstrated model extraction on Autonomous Vehicle using Gradient-Descent based methods [ACSAC'22].

Classical Music

Qifan Zhang is also a crazy fan of classical music. Since the age of 7, Qifan starts to learn the clarinet under the supervision of Prof. Xie Jingquan, Prof. Tian Yaohui and Prof. Wang Zhenxian from Nanjing University of Arts. After he came to the United States, he is honored to follow the instruction of Prof. Boris Allakhverdyan, principal clarinetist of Los Angeles Philharmonic as well as faculty member of Herb Alpert School of Music, University of California, Los Angeles.

Many thanks to Prof. Dr. Geoffrey Pope and Prof. Emeriti Dr. Stephen Tucker, he has been appointed as the principal clarinetist of UCI Symphony Orchestra, Department of Music since 2020.

In Feb 2024, Qifan won 2024 UCI Concerto Competition.

Every serious classical clarinetist will own both a B-flat and an A clarinet.
