Dr Sai Kiran Rajendran

Dr Sai Kiran Rajendran is a Lecturer (Teaching and Research) in Physics at the University of Dundee. His research focuses on the nanofabrication, characterisation, and laser spectroscopy of optoelectronic materials and devices, with applications in strong light-matter coupling, exciton-polariton physics, and emerging quantum technologies. His work spans hybrid organic-inorganic photonic systems, Rydberg excitons, semiconductor microcavities, and perovskite-based quantum materials.

Dr Rajendran has contributed to several UK and international research projects funded by EPSRC, Leverhulme Trust, Carnegie Trust, and the European Commission, working with collaborators at the University of St Andrews, the University of Strathclyde, University of Sheffield and Politecnico di Milano. His research has resulted in publications in leading journals.

His teaching experience spans undergraduate, postgraduate, and doctoral programmes, where he integrates research-led approaches into teaching to bridge the gap between fundamental concepts and contemporary research challenges. He is particularly interested in developing students' understanding of modern photonics, quantum technologies, and experimental physics through inquiry-based and research-informed learning.
