Our Team
Hexi has already welcomed you at the door and now invites you to meet the people behind the lab. We are an international group of researchers brought together by our passion for paleoceanography. With members from many different backgrounds, we see ourselves not just as colleagues but as a big family—working, learning, and exploring the past oceans together. So, let’s meet the team!
Lab Researchers
Jeroen has been an associate professor at IONTU since 2022. Before that he studied in Utrecht, did his PhD at Geomar, Kiel, and was postdoc for ages at MARUM, Bremen. His interests include using mostly foraminifera for paleoceanography/climatology, micropaleontology, inorganic geochemistry on timescales from the present to the Pliocene, Miocene, and anything that catches his attention. Outside science he spends a lot of time traveling and growing cacti.

Jeroen Groeneveld, PhD
Associate Professor
Raj started his tenure as an NSTC postdoctoral researcher on March 1, 2025, with Prof. Jeroen Groeneveld at NTU. He obtained his PhD from Indian Institute of Technology (IIT) Kharagpur, India. His areas of interest include micropalaeontology, paleoceanography, paleoclimatology, and sedimentary geochemistry. He employs methods such as foraminiferal taxonomy, abundance counts, stable oxygen and carbon isotopic analysis, Mg/Ca thermometry, and bulk sedimentary major, trace, and rare earth elements (REEs).
Raj S. I. S. Podder, PhD
Postdoctoral Researcher
Yu-Hsin completed her master’s degree in our lab in August 2025 and is now a research assistant. During her master’s study, she focused on the planktic foraminifer G. hexagonus to explore Pliocene Oxygen Minimum Zones (OMZs). Her work included machine learning–assisted porosity analysis, trace element analysis, data processing, and time-series studies. Besides her scientific work, she is our go-to Mandarin helper and helps build the lab’s website.

Yung-Hsiang (Austin) starts his master's program at IONTU in the spring of 2026. His curiosity and passion for the ocean gradually led him toward the fields of paleoceanography and geochemistry. At present, he is serving as an Earth Science teaching intern at Chenggong High School, where he brings scientific knowledge into the classroom and inspires students to explore the natural world. Beyond academics, he enjoys writing, capturing subtle traces of time and life through words

Yung-Hsiang Chang, BSc
Master Student (2026-)
As a paleoceanographer and former postdoctoral researcher at the Foram Lab, Shraddha specializes in studying late Cenozoic climate variability across the Pacific and Indian Oceans. Her work at the lab involved using geochemical proxies, such as Mg/Ca thermometry and stable isotopes of oxygen, carbon, and nitrogen in planktonic foraminifera, to reconstruct biogeochemical cycling in the Eastern Equatorial Pacific since the onset of Northern Hemisphere Glaciation.

Administrative Assistant
Hexi is a planktic foraminifer, Globorotaloides hexagonus, serving as an important indicator of Oxygen Minimum Zones (OMZs). Alongside Hexi are two little astronaut friends, Obi (Obliquity) and Precy (Precession), who represent the orbital forces often compared in paleoceanographic studies. Together, this trio symbolizes how microfossils and orbital cycles help us uncover the rhythms of Earth’s past oceans.
