Welcome to Chatterjee lab!

 

Our research group uses a combination of interdisciplinary approaches including chemical engineering, synthetic biology, systems biology, molecular biology, microbiology, metabolic engineering and computational biology to address key global challenges including medical and energy needs. We are interested in adopting an integrated mathematical modeling and experimental approach to investigate fundamental and medically relevant issues such as understanding the molecular mechanisms responsible for antibiotic and antiviral resistance, and for developing “next-generation smart antimicrobials” by rationally engineering novel therapeutics that target essential bacterial/viral genes in a potentially resistance-free manner. We study genetic regulatory networks that control propagation of infectious diseases, with the goal of discovering novel drug targets for therapy. Using synthetic biology tools we design, construct and engineer modular synthetic genetic devices that can achieve higher-order biological computation, for variety of biotechnological and bioenergy applications. To this end, we engineer biological parts such as transcription factors, promoter sequences, receptors, feedback loops, and regulatory RNA to build complex genetic networks that can be used to optimize cellular machinery for production of bio-fuels and pharmaceuticals, and for gene therapy applications. Using these genetic devices, we apply systems biology approaches to understand functioning of complex genetic networks and to build rules to manipulate such networks.

Antibiotic resistance updates

 

According to the 2013 Center for disease control report, infection from antibiotic resistant “superbugs” affects nearly two million people each year in the US, killing at least 23,000 people annually due to absence of effective antibiotics. We now face an immediate risk of entering a post-antibiotic era. This problem is further worsened by the fact that current antibiotic discovery research is limited, and that resistance to new antibiotics is inevitable due to natural tendency of microbes to evolve. In our lab, we are working towards developing different complemenatry solutions to this problem. Here are some of the latest news releases on the current state of antibiotics and antibiotic resistance.
