George Thomas' Group
@KGT_Lab
Prof. K. George Thomas' lab at IISER Thiruvananthapuram (@tvmiiser) . We focus on light-matter interactions in molecules and nanomaterials.
From detailed synthesis strategies to post-synthetic tweaks, ensemble & single-particle photo-physics, and real-world applications. Check out our latest review @ACSEnergyLett. pubs.acs.org/doi/10.1021/ac… Congratulations to @DevikaRajan17 @manoj_bhaskarn @Swathik97 @ AnoopThomas 👏
Congratulations to Dr. Livin Paul @Livinpaul2 on successfully defending his PhD thesis: Quantum Emitters in Plasmonic Field: From Ensemble to Single-Particle Spectroscopy. Grateful to Prof. Jaydeep Basu @iiscbangalore for serving as external examiner and for his valuable insights


Here are some glimpses of @ICP2025. Happy to be a part of this. It was truly enriching, and thank you all for the fruitful discussions.




Excited to share our PhD student @timi_titus12 gave an oral presentation at the 32nd International Conference on Photochemistry @ICP2025. Thankful to the organizing committee for this wonderful opportunity. @tvmiiser


Our latest work explores the hidden role of interchromophoric Interactions in determining the sign of bisignated CD signals, is now out in @JPhysChem. Congratulations @Sujith83535752, @AiswaryaE3, and our collaborators for the wonderful work👏 @tvmiiser pubs.acs.org/doi/10.1021/ac…
Our latest paper is just out in @NatureComms nature.com/articles/s4146… Here we show that light-matter strong coupling can modify the ground state intermolecular interactions of organic chromophores and subsequent emission properties without tweaking their chemical structure.
