Marine Isotope Laboratory
Meet the team
Yu-Te Alan Hsieh
Principal Investigator
Assistant Professor in Chemical Oceanography
I am a geochemist and chemical oceanographer. I am interested in isotope geochemistry and applications of using geochemical tracers to understand the ocean. One of my primary research goals is to apply isotope tracers to improve our understanding of different chemical inputs and outputs in the ocean (e.g., atmospheric deposition, continental runoffs, mid-ocean ridges, sediment-water interface, marine productivity and internal cycling).
Po-Kai Daniel Yang
Graduate Student
Daniel is a masters student. He graduated from the University of Hong Kong with a bachelor’s degree in Chemistry and a minor in Japanese. He likes traveling and making new friends. His thesis will focus on to what extent biological uptake of Ba contribute to marine fractionation of Ba isotopes.
Ya-Zhen Jen Wu
Graduate Student
Jen is also a masters student at IONTU. She has a broad interest in isotope geochemistry research. Currently she is working on a project about applying Ba isotopes to study cold seeps and mud volcanoes around the South West continental margins of Taiwan. When she is not in the labs, she likes outdoor activities and enjoys the beauty of nature.
You-Cheng Thomas Yang
Graduate Student
Thomas joined MISO as a summer program student. He has been working on projects that focus on using barium (Ba) isotopes in Singaporean corals to reconstruct the changes in Southeast Asian monsoons. He is now a master's student at IONTU and will continue to work on Ba isotopes in marine environments. He is also very good at volleyball.
I-Jy Hsieh
Administrative Assistant
I-Jy has joined our group from August 2022, but she has been working as an research assistant in IONTU for many years. She likes Taiwanese food, pop music and walks.
Meng-Hsin Morris Wu
Research Assistant
Morris, a dedicated ocean lover, earned his MS degree in coral reef ecology from IONTU. Despite being introverted, he passionately engages in outdoor pursuits like SCUBA diving, snorkeling, and hiking. These experiences drive his ambition for influential research and revealing the ocean's secrets. With a deep affinity for nature and a strong curiosity for ocean exploration, Morris invites us to share in his journey of oceanic discovery.
Flora Wu
Undergraduate Student
Flora is an undergraduate student in the Department of Agricultural Chemistry at NTU. She falls in love with the ocean after learning scuba-diving and is strongly considering to make ocean exploration as a lifelong career. She is currently working on a project about chemical effects of Ba isotopes in Yinyang Sea, an acid mine drainage system in the Northern Taiwan. She has a diverse range of interests with a particular passion for photography. She enjoys discovering different possibilities in life through the lens of her camera.
Chih-Ting Henry Chiu
Undergraduate Student
Henry is our summer program student. He is also an undergraduate student in the Department of Geosciences at NTU. Henry is working on a project to look at different controls of Ba cycling in estuaries.
Former MISOs
Pinyu Huang
Administrative Assistant
Pinyu is helping a lot in the early stages of setting up our labs. She is also very good at managing our budgets. She likes hiking and outdoor activities. She is also a foodie. She always know where to find the best food.
Zhongli Chua
Research Assistant
Zhongli graduated from the Department of Geosciences at NTU. He is interested in natural science and exploring the wonders of the Earth. He likes many outdoor activities, such as basketball and scuba diving etc.
Yi Chen
Graduate Student
Yi is a masters student at IONTU. He is interested in studying different isotope systems in marine environments. He also likes skateboarding and scuba diving.
Bing-Yu Zeng
Undergraduate Student
Bing-Yu is an undergraduate summer program student. He is majoring in Earth Sciences at NCKU. His current summer project involves investigating the uptake of Ba in coccolithophores and exploring its implications for Ba isotope fractionation.
