I am an final year students in Biomedical Engineering at the Ho Chi Minh City University of Technology, Vietnam National University Ho Chi Minh City, Vietnam. My research interests related to content of some elements in soil and the influence of metal elements in soil to biological activities from medicinal herbs. My graduate thesis was about studying on the content of some metals in soil by XRF method and evaluating their effect on the active substances content of methanol extracts from some medicinal plants. Now, I continues my Master’s degree in Biomedical Engineering at Ho Chi Minh City University of Technology, Vietnam National University Ho Chi Minh City, Viet Nam.
