Ultrafast Optical Spectroscopy and Microscopy Laboratory
Embedded Files
Department of Chemistry, NIT Warangal
Our research group is located at the Department of Chemistry, National Institute of Technology (NIT) Warangal. We explore light-matter interaction by using optical spectroscopic tools with a special emphasis on the correlation between the photoinduced ultrafast processes in the molecules/materials and their implications in biological processes or device properties.
Our research vision is to explore physical chemistry of biological systems or bio-inspired artificial systems to achieve high performance devices with intelligent design in order to respond to the climate change (mitigation and adaptation). Our research area is highly interdisciplinary emcompassing physics, chemistry and biology. To explore these systems, we use primarily ultrafast transient absorption (TA) spectroscopy, time resolved fluorescence spectroscopy and microscopy techniques.
For details about our research areas, please refer to the “Research” section.
Ph.D. positions are available for CSIR-UGC-JRF/INSPIRE candidates.
One PhD position under Institute fellowship will be available in July- 2026 admission session.
Postdoc candidates interested in applying ANRF-NPDF may contact Dr. Samim Sardar (samimsardar@nitw.ac.in) for further details.
