Senior🎓
Top SchoolJustin Furuness is a software engineer and Assistant Professor in Residence with a PhD in cybersecurity focused on BGP security and eight years of hands-on experience building scalable research and production systems. He created BGPy, a widely used open-source Python BGP simulator with nearly 100k downloads that powers academic and NIST research, and turned it into bgpsimulator.com to teach, visualize, and auto-grade BGP labs for active users and instructors. At UConn he led large-data efforts—ETLing >100 GB of internet data, adding C++ PyBind11 bindings and highly optimized SQL—to reverse-engineer AS policies and evaluate novel defenses now submitted to top venues. In industry he led Python backend development and complex FHIR integrations at NeuralFrame, cutting runtimes from 28 hours to 20 minutes and achieving 100x query speedups via Mongo schema redesign. He pairs deep protocol security research with pragmatic engineering, and even builds user-focused Python tools—from voice web navigation for injured hands to automated housing and media utilities—highlighting a knack for turning research into usable software.
