Leo Meyerovich founded Graphistry to supercharge visual investigations of event data by unifying end-to-end GPU acceleration, workflow automation, & graph analytics. Data teams use it for problems like US cybersecurity, fraud analysis, cancer genomics, and tracking medical misinformation. Graphistry builds on his research at UC Berkeley. Leo's most referenced research is in secure programming languages, and his award-winning projects include the first functional reactive web language, the first parallel web browser, programmable GPU visual analytics, and the sociological foundations of programming languages. These ideas are used by popular browsers and web frameworks, and received awards including SIGPLAN 10 year Test of Time, Best of Year, and multiple best paper awards.
