Oege de Moor is the CEO and Co-Founder of Semmle. Prior to founding Semmle, he spent 21 years as a Professor of Computer Science at Oxford. During a sabbatical from Oxford, he joined Microsoft as a Visiting Researcher, working with Charles Simonyi (the original creator of Word and Excel) on a new type of programming environment. While at Microsoft, he became interested in how software was becoming increasingly more complex, and how this contributed to security vulnerabilities and other bugs being extremely hard to identify and eradicate. 

When Oege returned to Oxford, he decided to found Semmle to start cracking this problem, leaning on numerous insights and years of experience working with security-forward companies. Under Oege's leadership, the Semmle team built the QL engine behind its LGTM platform to find vulnerability variants, leaning on insights from its community of 700,000 developers, and extend any company's security research team.
