Dr Sudhagar Pitchaimuthu

Dr. Sudhagar Pitchaimuthu, is Ser Cymru-II Rising Start Fellow at SPECIFIC, College of Engineering, Swansea University (SU). He is leading "Multifunctional Photocatalyst and Coating" research group at SU. His research expertise is ‘nanomaterial synthesis and coatings’ towards constructing low-cost solar energy driven photoelectrochemical system/devices.

Mainly his group focuses on utilising the abundance, sustainable solar energy for multifunctional applications such as energy conversion devices (solar cells and solar fuel cells), environmental clean-up (photocatlytic water treatment, air purification) and biosensors. His current research interest is to develop a) semiconductor thin film based solar light photoabsorbers (metal oxide, metal chalcogenides), b) Quantum dot films/coating, c) less expensive Pt-free water oxidation/reduction catalyst.  His research is jointly funded by Welsh Government and European Commission through European Regional Development Fund (ERDF) under ​Sêr Cymru II-Rising Star Fellowship scheme (£ 1 M) over five years (2017-2022).

Dr. Sudhagar graduated from Physics discipline, Bharathiar University, India in 2009. He was working as Research Assistant Professor during 2009-2013 under Prof. Yong Soo Kang at Center for Next Generation Dye-sensitized Solar Cells in Hanyang University, South Korea. Concurrently, he has been serving as visiting scientist to Department of Applied Physics, University of Jaume I, Spain from 2011. He was a recipient of JSPS award from Japan Society for the Promotion of Science, Japan in 2013. Sudhagar has published more than 70 articles in peer-reviewed journals (citations: 1904, h index: 27), and contributed 5 book chapters. He also chaired, and co-organised 5 international conferences and workshops.

  • EG-187 Engineering Analysis for Materials 1

    To provide a grounding in engineering analysis methods for materials students. The module will cover the most important analytical functions and methods used in engineering and will relate these to common materials-related examples. The module will ensure the required grounding in methods and techniques for those who have not previously covered this area, or who are returning after a gap. It will also provide opportunities for extension to more complicated examples for those who have more prior experience.
