Andrei Lapets is a Postdoctoral Fellow at the Hariri Institute. His current research efforts are aimed at evaluating and improving the accessibility of automated formal reasoning assistance tools. Many such tools have been developed by the formal verification and programming languages communities, but there are still many opportunities to integrate multiple tools behind accessible interfaces in order to better support users engaging in university instruction and research in specific domains. There is also a need to more rigorously evaluate the usability of such tools using techniques developed by the user interface design and human-computer interaction communities. Towards these ends, Andrei is working with members of the iBench Initiative, and the Network Security and Cryptography groups at the Boston University Computer Science Dept. to develop and evaluate accessible domain-specific environments that integrate multiple automated formal reasoning assistance tools and techniques. Andrei is also an instructor in the Department of Mathematics and Statistics at Boston University, where he employs automated assistance tools with students in the classroom. Andrei has a Ph.D. in Computer Science from Boston University, as well as S.M. and A.B. degrees in Computer Science from Harvard University.
