Margaret Weng
Postdoctoral Scholar, Earth System Science
BioMaggie Weng is a NASA postdoctoral fellow in the Dekas lab at Stanford University. Her research focuses on understanding molybdenum availability and uptake strategies at deep-sea methane seeps. She uses culture-independent techniques including metagenomics, metatranscriptomics, and stable isotope probing to understand whole-community dynamics. She earned her PhD from Georgetown University in 2024 with Dr. Sarah Stewart Johnson, where her research focused on microbes in hypersaline environments, and her bachelor's degree in 2019 from Washington University in St. Louis. She is interested in microbial persistence at the edge of possibility, including extreme environments and polluted sites, and how microbial communities contribute to bioremediation and ecosystem stability. She always says yes to fieldwork and as a consequence has found herself in the Atacama Desert, Kerlingarfjöll, Iceland, and Western Australia as well as a commercial salt factory in San Diego, CA. When not in the lab she is an avid writer, hiker and knitter. Her fiction and nonfiction writing have appeared in The Los Angeles Review and Northern Woodlands magazine. When out in the woods, she appreciates a good biofilm almost as much as a good view.

Weiwei Zhan
Postdoctoral Scholar, Earth System Science
BioI study the coupling between the global carbon and water cycles under climate change. Specifically, I investigate how plants regulate carbon uptake and water loss as atmospheric CO2 rises and water limitation intensifies, and how these responses feed back on the global environment. I develop hybrid physics–machine learning approaches and combine them with the expanding record of satellite and in situ observations to test hypotheses about ecosystem function.

Xiaojian Zheng
Postdoctoral Scholar, Earth System Science
BioDr. Xiaojian Zheng is a postdoctoral scholar in the Department of Earth System Science at Stanford University, working with Dr. Yuan Wang. His research targets aerosol–cloud–climate interactions, combining ground-based, airborne, and satellite observations with global and convection-permitting models, and leveraging machine learning throughout the analysis.
Xiaojian's current research directions span deep learning-based estimates of regime-dependent aerosol–cloud interactions, machine-learning emulation of aerosol microphysics inside Earth System models, and the circulation control of convection, heatwaves, and regional air quality.
