Summary
👤
Senior🎓
Top SchoolJoshua Kempner is a Principal Engineer and systems architect with nearly two decades of experience bridging astrophysics-derived quantitative modeling and production software for life sciences imaging and drug discovery. He has led architecture and global software organizations at PerkinElmer and Revvity, and now drives product development in FP&A as lead developer at PowerModels, bringing deep expertise in event-driven, CQRS/ES systems and distributed architectures. His technical toolbox spans C#, .NET, C++, MATLAB and event stream databases, applied to diffuse optics, tomographic reconstruction, and visualization for preclinical and screening platforms. Joshua combines hands-on algorithm development—rooted in photon diffusion and astrophysics modeling—with strategic product and portfolio decisions, including software due diligence for M&A. He’s known for turning complex mathematical models into maintainable, componentized software assets and for standing up governance like Architecture Review Boards and company-wide software censuses. Based in Massachusetts, he pairs academic rigor (PhD in Astronomy) with pragmatic leadership across global teams and regulated R&D environments.
