My research interests are in network measurement and anti-abuse for improved stability and security of the Internet. I lead the Internet Measurement and Anti-Abuse Laboratory (IMAAL). Our research includes (but is not limited to) the following areas:
- DNS/DNSSEC deployment and measurement
- IPv6 deployment and measurement
- DDoS prevention and mitigation techniques
- Our paper on SPF validation was recently accepted to CoNEXT 2021!
- Our paper on network security was recently accepted to ICNP 2021!
- Our paper measuring DNS cookie usage was recently accepted to PAM 2021!
- Our paper on network security was recently accepted to IMC 2020!
- Our paper on DNS privacy was recently accepted to CoNEXT 2019!
- Our paper on NSEC3 zone size detection was recently accepted to PAM 2019!
- Profs. Bryant and O'Hallaron at CMU recently featured in a blog post the little Computer Systems-based song I wrote and performed with some BYU Computer Science students.

Dr. Casey Deccio is an Assistant Professor in the Computer Science Department at Brigham Young University (BYU). He earned B.S. and M.S. degrees in Computer Science from BYU in 2002 and 2004, respectively, and received a Ph.D. from UC Davis, in Computer Science, in 2010.
Prior to coming to BYU, Dr. Deccio was a Senior Research Scientist at Verisign Labs since 2014, where his research included DNS ecosystem tools, monitoring, measurement, and modeling, with the objective of increasing stability, security, and safety of the Internet. Before that he was a Principal Research and Development Cyber Security Staff member at Sandia National Laboratories, where he had been employed since 2004 and where he was responsible for network-related research and development, including DNSSEC and IPv6 deployment efforts. While at Sandia he developed DNSViz, the widely used tool for DNS analysis and visualization. He also served as an ICANN Research Fellow supporting the Security and Stability Advisory Committee (SSAC) in 2013.
Outside of work, he enjoys making music and participating in recreational activities with his wife and five children.
I sing barbershop with a number of BYU Computer Science students in a group called Sing++. Here is a musical tribute to my systems class.
