Personal Statement

Following a Bachelor's and a Master’s degree in Biochemistry, I carried out by doctoral studies in Bharathiar University, India in collaboration with National Dong Hwa University, Taiwan, studying molecular mechanisms involved in combination therapy of neferine and doxorubicin to induce  autophagy and apoptosis in lung cancer cells. Then I have relocated to United Kingdom to pursue my postdoctoral fellowship in cancer. At the University of Liverpool, I studied the apoptosis mechanisms induced by maritoclax and Dinaciclib. Further in Bangor University, I have worked on the cellular uptake mechanism and anticancer efficiency of nitro-reductase coated gold magnetic nanoparticles for directed enzyme prodrug therapy (DEPT) in ovarian cancer cells. Currently, I am studying the role of NRF2 in ErbB targeted therapy in breast cancer cells.
