Sze Ling Ho 賀詩琳, Dr. rer. nat.
Principal investigator
Works with paleoceanographic proxies and paleoclimate reconstruction, using geochemical signature in biomarker and microfossils. Studied and worked in Japan, Germany, and Norway, before moving to Taiwan as a faculty member of IONTU. Currently associate professor at IONTU. Also serves as an external editor for Springer Nature journal Communications Earth & Environment, and associate editor for AGU journal Paleoceanography & Paleoclimatology. Co-lead/steering committee member of the PAGES working groups PlioVAR and PlioMioVAR, and PMIP-DATA working group.

Pierrick Fenies, PhD
Postdoctoral researcher
I reconstruct past environmental changes in the northwest Pacific off Taiwan using a multiproxy approach.
Syed Azharuddin, PhD
Postdoctoral researcher
Syed’s current research at IONTU involves Plio-Pleistocene sea surface temperature reconstruction using biomarker proxies in the Northern Pacific.
Other ongoing research includes –
1. Late Pleistocene-Holocene deoxygenation history, sea surface temperature, carbonate chemistry and pCO2 changes in the NE Arabian Sea using nitrogen isotopes, foraminifera Mg/Ca and boron isotopes.
2. Holocene variation of atmospheric greenhouse gas concentrations (nitrous oxide) using South Pole ice cores.
3. Mid-Holocene multidecadal air temperature reconstruction using fluid inclusion isotopes in the stalagmites of Japan.

Priyansha Gupta, PhD candidate
Research assistant
I am a researcher with expertise in marine pollution studies, particularly focusing on microplastics and their associated chemicals. My recent work involves assessing temporal variations of biomarkers and microplastics in the northern South China Sea using sediment trap time series.
