Dr Siva Karuturi

Siva Karuturi is working jointly in the Research School of Electrical, Energy and Materials Engineering and the Research School of Physics. He received a PhD degree in 2013 from Nanyang Technological University in Materials Science and Engineering. Siva worked as a postdoctoral fellow in the School of Photovoltaics & Renewable Energy Engineering at the University of New South Wales before moving to ANU in 2014. He was a recipient of the Discovery Early Career Researcher Award grant from the Australian Research Council in 2015. 

His research interests lie primarily in the areas of solar energy conversion and materials engineering with extensive experience in the design of semiconductor photoelectrodes and integrated cells for hydrogen generation. He recently played a key role in securing grant funding from the Australian Renewable Energy Agency (ARENA) and ANU towards addressing key technological challenges advancing the commercialisation prospects of solar hydrogen technologies.
