Sylvia Dee

Sylvia Dee is an assistant professor and climate scientist at Rice University specializing in atmospheric modeling, water isotope physics, and paleoclimate data-model comparison. She completed her undergraduate degree in Civil and Environmental Engineering with certificates in Geological Engineering and Environmental Sciences at Princeton University, and her Ph.D. at the University of Southern California Earth Sciences department. She previously held postdoctoral fellowships at the UT Institute for Geophysics and Brown University. 

Sylvia's research projects include topics in climate modeling and climate of the past millennium, using general circulation models (GCMs) and proxy system models (PSMs) to explore the dynamics of the tropical climate system. 

Sylvia is the developer of the water isotope-enabled, fast-physics atmospheric dynamical model, SPEEDY-IER, and a public platform for proxy system modeling development, PRYSM. This modeling platform allows for multi-centennial simulations of common era climate with water isotope physics, which, coupled with proxy system models for proxy records, facilitates the comparison of model output to paleoclimate data.

Xiaojing Du

Dr. Xiaojing Du is a postdoctoral researcher and paleoclimatologist at Rice University. She integrates proxy measurements, climate model simulations, and instrumental observations to understand the hydroclimate variability on interannual to orbital time scales from the LGM to present. She is particularly interested in tropical hydroclimate changes and the teleconnections between tropics and extratropics. Her work has investigated the cause of hydroclimate changes over the Indo-Pacific Warm Pool during the last deglaciation, and the relationship between ENSO and Southern California precipitation over the Holocene. At Rice, she plans to investigate the evolution of the ENSO-Asian monsoon relationship over the Common Era. Xiaojing earned her Ph.D. from the University of Michigan, Ann Arbor. Before joining Rice, she was a Voss Postdoctoral Fellow at Brown University.

M. Rezaul Haider

Dr. Muhammad Rezaul Haider is a Postdoctoral Researcher studying the impact & assessment of climate change on Mississippi river basin hydrology. His PhD research activities include dealing with spatial weather and climate data, and range from post-processing of sub-seasonal to seasonal (S2S) forecast, bias correction, and spatial downscaling of the forecast utilizing hindcasts and corresponding ground-truths to validation of forecast. Dr. Haider received his Ph.D. in Environmental Engineering from the University of Connecticut in 2022. 


Kyle Niezgoda

Dr. Kyle Niezgoda is a Postdoctoral Scholar studying the role of parameterization schemes on shallow convection in climate models. He received a B.S. in Environmental Science and Mathematics from Emory University in 2014, and a PhD in Earth, Ocean, and Atmospheric Sciences from Oregon State University, where his research broadly focused on the use of water isotopes in general circulation models as tools for model validation and paleoclimate reconstruction. Kyle was born in Delaware, and enjoys board games, skiing, playing the drums, and good food.
