Wen-Hsuan is a sea-going trace metal geochemist, studying the distribution of trace metals and their isotopes in the ocean. In addition to distribution, Wen-Hsuan also tries to use different tools to quantify and characterize the sources of trace metals to the ocean, particularly, focusing on developing different methods to precisely measure the isotopic composition of trace metals to identify their sources to the ocean. Potentially, these methods and isotopic tools can be applied to study the isotopic fractionation in different natural systems to gain further understanding of elemental cycling.

The major focus of Wen-Hsuan's lab at NCKU is to improve our understanding of marine trace metal cycling. We love trace metals, so we are happy to involved in any research topic related to trace metals. Currently, one full-time research assistant and one full-time administration assistant are working in the lab. In the coming semester (Aug. 2025), four graduate students will join the lab for pursuing their master degrees. The lab is equipped with a SF-ICP-MS (Thermo Element XR) and a IR-MS (Thermo Delta plus XP) for measuring elemental concentrations and traditional isotopic compositions for different purposes. A trace metal clean booth (class-10000), with three class-10 benches, is also established for processing various samples under a clean condition without potential contamination. We are also capable for measuring several nutrients, including nitrate, nitrite, silicate, and phosphate, for different types of water samples.
