Dr Ratnam earned the BEng (Hons I) degree in Electrical Engineering in 2006, and the PhD degree in Electrical Engineering in 2016, from the University of Newcastle, Australia. She subsequently held postdoctoral research positions with the Center for Energy Research at the University of California San Diego, and at the University of California Berkeley in the California Institute for Energy and Environment (CIEE). During 2001–2012 she held various positions at Ausgrid, a utility that operates one of the largest electricity distribution networks in Australia. Dr Ratnam currently holds a Future Engineering Research Leader (FERL) Fellowship from the Australian National University (ANU) and she joined the Research School of Electrical, Energy and Materials Engineering at ANU as a research fellow and lecturer in 2018. She also holds an ongoing affiliation with CIEE at UC Berkeley, and is a research lead in the Battery Storage and Grid Integration Group (BSGIP) at ANU. Her research interests are in developing new paradigms to control distribution networks with a strong focus on creating a resilient carbon neutral power grid.
