Weiran Li (Alex) is a volcanologist and petrologist by training. She received her B.S. (in Geochemistry) and B.A. (in Art History) in 2012 from Peking University (PKU), China. During 2012-2014, she was a master student at PKU working on using the40Ar/39Ar isochron method to date Quaternary volcanic rocks from Changbaishan volcano (China). In August 2014, she joined the Interdisciplinary Graduate School and Earth Observatory of Singapore at NTU, and started to work on the pre-eruptive magmatic processes of subduction-zone volcanoes, under the supervision of Professor Fidel Costa. In the third year of her PhD, she received the Dr. Stephen Riady’s geoscience scholarship, and had a three-month visit at the Ruhr University at Bochum (Germany) to perform diffusion experiments. With the work from this project, she received the Best Student Presentation Award from the EMPG conference in Clermont-Ferrand (France) in 2018.
Weiran’s PhD research focuses on using mineral apatite to evaluate the contributions of magmatic volatile budgets and ascent rates to different types of eruptions. Her work combines a variety of approaches from field observation, through petrography, bulk and in-situ chemical analyses, diffusion experiments, thermodynamic calculations, and numeric modelling. She has also converted her models into free online calculators for the convenience of application by other researchers. Her goal is to become an expert in volatile behaviour in subduction-zone magmatism, and to explore the volatile cycles between the atmosphere and mantle.
