Abstract

2018 marked the 90th anniversary since Alexander Fleming first discovered penicillin. However, despite over 90 years of research, infectious diseases are still amongst the top ten leading causes of death worldwide. Infectious diseases are not only placing significant burden to developing nations, they could also spread at threatening pace globally, putting every nation and every person at risk. Our research is driven by the desire to understanding the molecular mechanisms that allow bacteria to survive. In this talk, we will discuss two of our recent projects in combating infectious diseases through structural, biochemical and computation approaches.

We will report our progress in understanding how Mycobacterium tuberculosis regulates the use of different carbon sources to survive inside our body during latent infection. We will also describe our work on the development of new chemical agents to tackle an emerging antibiotic resistance mechanism against colistin, an antibiotic of last resort.
