Bacterial Cell Wall, Its Biosynthesis and Recycling and Its Nexus to Antibiotic Resistance

Research focuses on the bacterial cell wall, its biosynthesis and recycling. The research team studies every aspect of the process from complex structures for the polymeric entity to the reactions of the various enzymes that are involved with it.  As an off-shoot of these studies, scientists explore discoveries of antibiotics that interfere with the cell-wall processes.

Research Focus

  • Biochemistry

    At the EIGH, our researchers use biochemistry - or the study of chemical substances and their vital role within living organisms - to combat various global health challenges, such as antibiotic resistance and counterfeit drugs.

  • Computational Science

    Computational science is a multidisciplinary field that utilizes advanced computing to understand and solve complex problems. Researchers at the EIGH develop computational models, hardware, software, data management, and more to tackle a variety of global health concerns.

  • Infectious Diseases

    At the EIGH, our researchers work to combat a number of various illnesses, including infectious diseases caused by organisms like bacteria, viruses, fungi, and parasites. These diseases can also be spread from one person to another and may be transmitted from animals to humans. 

  • Molecular Biology and Microbiology

    Researchers at the EIGH use microbiology, which encompasses the study of an entire microorganism, and molecular biology, or the interactivity between molecules within a cell of an organism, to better understand disease and improve global health.
