Forschungsgebiet
Dr. Kumar's research focuses on the development and application of optical nanospectroscopy and nanoimaging. His work involves advancing AFM and STM-based plasmon-enhanced optical spectroscopies, including Raman, fluorescence, and photoluminescence, to enable hyperspectral molecular and chemical imaging at the nanoscale. Dr. Kumar applies these cutting-edge methodologies to study a diverse array of materials, such as catalytic materials, biomaterials, polymeric materials, photovoltaic materials, and two-dimensional materials including single-layer graphene and transition metal dichalcogenides. Additionally, his research also explores chemical transformations at crystalline metal surfaces and solid-liquid interfaces at the nanoscale.
Curriculum VitaeDr. Naresh Kumar is a Senior Scientist and Lecturer in the Department of Chemistry and Applied Biosciences at the Swiss Federal Institute of Technology (ETH) Zurich since 2020. Dr. Kumar earned his Bachelor of Technology in Engineering Physics from the Indian Institute of Technology Delhi and went on to receive his Master of Research in Physics at the Nanoscale from King's College London, graduating with distinction. He obtained his PhD from Utrecht University, Netherlands, under the supervision of Prof. Bert Weckhuysen, where he focused on the development of Tip-Enhanced Raman Spectroscopy (TERS) and its application to heterogeneous catalysis. In 2011, Dr. Kumar joined NPL as a Research Scientist, where he spearheaded the development and application of TERS. He established a state-of-the-art AFM-TERS system at NPL and contributed to numerous interdisciplinary projects. His work spans diverse scientific fields, including heterogeneous catalysis, organic solar cells, polymer blends, nanoscale chemical imaging of solid-liquid interfaces, and 2D materials such as graphene and single-layer MoS2. For his scientific accomplishments, Dr. Kumar received the prestigious Rayleigh Early Career Award from NPL in 2016 and was promoted to Higher Research Scientist in 2017. From 2020 to 2023, Dr. Kumar served as an Visiting Professor at the School of Sciences, Hangzhou Dianzi University, China. In 2023, he received the esteemed Masao Horiba Award for advancements in optical nanospectroscopy to study novel semiconductor materials. Dr. Kumar is a frequently invited speaker at international scientific conferences in the fields of optical nanospectroscopy and nanoimaging. |
