Shwetha Niddodi joined the Pacific Northwest National Laboratory as Post Master’s Research Associate in May 2016. She was converted into full staff engineer in October 2016. Before joining PNNL, she worked as a software engineer for many years in a well-recognized software services company in India. At PNNL, she is part of the development team of VOLTTRON, which is an agent based distributed and sensing platform that provides integrated services for data collection, data monitoring and data archival of building devices, grid simulations, electric vehicles etc. Her activities involve refactoring the underlying message bus to improve performance, usability and scalability of the platform. She also works on other projects that involve integrating new SCADA communication protocols into existing grid co-simulation framework, developing methodology for safe autonomous vulnerability scanning of OT devices in electrical infrastructure.
