We aspire to translate the basic research into therapeutic applications.

Currently, we are focusing on the following research areas

1. Organic Synthetic Small Molecules and Anticancer Drug Development

We work on developing synthetic small molecules and chemical biology methods for developing targeted chemotherapy. We employ small-molecule probes to decipher the role of various DNA-binding proteins or transcription factors in genome stability,  repair,  plasticity,  oncogenesis, and tumor progression

2. CRISPR-Cas, Genome engineering, Functional Genomics

We focus on developing functionally enhanced CRISPR-systems for their broader and practical application in gene-editing. We employ protein-engineering and chemogenetics for precise cellular gene-editing and investigate their effect on gene-functions for prospective gene-therapy applications

3. Synthetic Biology and Anti-infective Drug Development

We are working on designing synthetic biology methods for developing precision anti-infective agents. Our primary targets are multidrug-resistant pathogenic bacteria like MRSA and Mycobacterium tuberculosis

Dr. Basudeb Maji’s research group (Chemogenetic Research Lab) at Bose Institute is working on the frontier of disease biology chemical biology, and medicinal chemistry problems. His lab mainly focuses on protein-engineering, genome engineering, and chemogenetics for precision gene therapy applications and chemopreventive development. His lab works on both organic synthesis and synthetic biology for developing synthetic small molecular probes for genetic and pathogenic diseases like cancer, muscular disorders, and bacterial infection.
