Staff Profile

William A. Casey

Senior Member of Technical Staff, SEI Cyber Threat and Vulnerability Analysis

Key Responsibilities

Research methodology to advance a Science of Cyber Security (SCS).  We have developed computational algorithms for malicious-code detection, characterization, and analysis to expose the malicious design goals (of malware) or aberrant behaviors of software (vulnerabilities/exploits).  Recently we have considered how these capabilities can be re-engineered into mobile and communicable formats that can be shared among agents within a Recommendation-Verification System.

Professional Background

Casey has worked in the areas of threat analysis, code analysis, natural language processing, genomics, bio-informatics, and applied mathematics in academia, industry, and government. Casey received his PhD in applied mathematics from the Courant Institute at New York University. He also holds an MS in mathematics from Southern Illinois University Carbondale, a master’s equivalency in computer science from the Courant Institute at New York University, and an MA in mathematics from the University of Missouri Columbia. Casey is a member of the American Mathematical Society (AMS) and Society for Industrial and Applied Mathematics (SIAM).
