Most recent SPIES graduate

Ajaya Neupane is the most recent PhD. graduate of the SPIES lab. Groundbreaking research (top-tier papers, NDSS14 best paper, NIJ/DoJ fellow). He is taking on a post-doctoral research scientist position at UC Riverside, working on UCR/CMU/PSU CyberSecurity Research Alliance project funded by ARL.

Congratulations and very best wishes for a bright future :-)




Two papers accepted to CCS 2017


The SPIES lab and collaborators have two papers accepted to ACM CCS 2017. Extremely fierce competition with only 151 papers making it to the program out of 836 submissions (an acceptance of just about 18%).



Journal paper accepted to TDSC

TDSC is a top journal in the area.

Emerging-Image Motion CAPTCHAs: Vulnerabilities of Existing Designs, and Countermeasures
