John Klein is a principal investigator and senior member of the technical staff in the Software Solutions Division at the SEI.

Klein is currently leading a project investigating how to automatically reconstruct the deployment architecture of a legacy system and developing a playbook to guide organizations through modernization projects. Klein also works with the Square Kilometre Array radio telescope team, who has adopted many of the SEI’s architecture practices to reduce risk in the design of this massive system.

Past projects at the SEI have included leading research to bring stakeholder preferences into the analysis of alternatives in system modernization projects and developing architecture approaches to big data systems. Klein has collaborated with an Australian research center on a big data reference architecture adopted by the Ministry of Defence and the Australian Federal Police; led a team that assessed analytics enterprise architecture for a large health-care provider; and coached Bursatec, the Mexican Stock Exchange, in architecture development for a new trading engine.

Before joining the SEI, Klein was a chief architect at Avaya, Inc., where he focused on communication analytics and multimodal agents, and an architect at Quintus, where he designed the first integrated multichannel contact center product. Klein was also a technical director at Raytheon, where he developed hardware and software solutions for radar signal processing and multispectral image processing.

Klein holds a BEng from the Stevens Institute of Technology, an MEng from Northeastern University, and a PhD in Computer Science from VU University Amsterdam.
