Kaustabh Kumar Maiti obtained B.Sc Chemistry (Honours) & M.Sc. in organic chemistry (specialization) from University of Calcutta (India) and thereafter awarded Ph.D from the same university in the year 2001. His Ph.D work based on development of synthetic methodologies of regio- and stereo-selective nitrogenous heterocycles by 1,3-dipolar nitrone cycloaddition with a wide variety of synthetic and naturally occurring diplorophiles. He started his professional carrier in leading pharmaceutical R&D’s in India, 2000-2003 (Alembic Ltd. and Sun Pharmaceuticals Industries Ltd.) where he worked in process development of generic drugs and drug discovery program. After industrial training, he joined postdoctoral research at Pohang University of Science and Technology (POSTECH, 2003-2007), South Korea, with Prof. Sung-Kee Chung and developed a series of novel non-peptide drug delivery system (DDS) using inositol and carbohydrate as scaffold. He moved to Complex Cabohydrate Research Center (CCRC), The University of Georgia, USA to continue second postdoctoral research. In CCRC he worked Prof. Geert-Jan Boons’s group (2007 -2009) in the field of glycopeptide, structural aspects of peptidoglycan and LPS. Before joining at CSIR-National Institute for Interdisciplinary Science and Technology (CSIR-NIIST), Thiruvananthapuram, he engaged at Singapore Bioimaging Consortium (under Biomedical Sciences Institute, A*STAR) as a research scientist (2009-2012) and explored surface enhanced Raman scattering (SERS) platform and SERS-nanoparticle tags as diagnostic tool for detection and imaging of cancer biomarkers. His current research interest focused on synthesis and biological evaluation of synthetic (peptide, non-peptide, dendron based scaffold ) and nano-carrier based drug-delivery system (DDS) for targeted delivery of small molecular drugs, proteins, nucleic acids and plasmid DNA. Also his interest on the development of multimodal theranostic nanoprobe for infectious diseases as well as cancer detection and imaging by SERS, fluorescence, MRI, photoacoustic as diagnostic modalities and PDT, PTT and combined chemo-immuno therapy. Presently his group initiated on natural product derived new phyto chemical entities (NPCEs) towards Hit / advanced Hit generation in cancer therapy.
