Dr. Ashutosh Mukherjee is a postdoctoral researcher at Hochschule Reutlingen, Germany, specializing in Raman spectroscopy, surface-enhanced Raman spectroscopy (SERS), and advanced nanoscale sensing platforms. His research focuses on the development of innovative three-dimensional (3D) plasmonic substrates and their integration with next-generation diagnostic technologies. He combines nanofabrication techniques, including two-photon lithography, with advanced optical system design and data-driven approaches such as multivariate analysis, PCA, and artificial intelligence (AI)/machine learning for intelligent spectroscopic diagnostics. His work aims to bridge nanotechnology, spectroscopy, and data science to enable robust, scalable, and application-ready solutions for biomedical diagnostics and chemical sensing.
