I'm currently working in different kinds of samples including biology samples (tissue, milk, blood, urine, digested fluid, etc.), marine samples (algae, fish, bacteria, etc.) on lipid-soluble arsenicals and their metabolism characteristic. The main research interests are how lipid-arsenicals influence human health, and its relevant health risks. Also, new analytical techniques (HPLC, ICPMS, ESMS, HR-ESMS, LA-ICPMS, SIMS) should be applied for ultra-trace determination.
