Research Interest:
Development of drug combination to counter antibiotic Resistance:
High occurrences of antibiotic resistance in bacteria are becoming an emerging problem worldwide. We are running out of antimicrobial drugs to counter the rapid rate of antibiotic resistance. There is an urgent need to develop new drugs or combinations of existing drugs that can effectively inhibit the growth and occurrence of antibiotic resistance. To solve this problem, we are investigating the effectiveness of FDA-approved drugs as antimicrobials in combination with antibiotics.
Cell-fate decision from mitosis to meiosis:
Cells undergo transformation within to achieve a specific stable phenotype through cell-fate decisions. The fundamental aspect of this is to convert momentary changes in gene expression by external signals. An important and very much coordinate cell-fate decision is the generation of haploid gametes from diploid progenitor cells by the process of gametogenesis. A fundamental aspect of gametogenesis is the specialized cell division, meiosis. This is unique to sexually reproducing organisms. The meiotic cell cycle generates the gametes that are crucial for the survival and evolution of species. The key feature of meiosis is the expression of genes that transform the mitotic cell division into the specialized meiotic divisional programme. The understanding of intrinsic and extrinsic factors responsible for changes of cell-fate decision from mitosis to meiosis is crucial to understand of the important biological process, meiosis.
