Xiaohan Wu

Xiaohan Wu is a Postdoctoral Fellow at the Canadian Institute of Theoretical Astrophysics specializing in theoretical astrophysics and cosmology. She earned her PhD from Harvard University studying reionization and the intergalactic medium (IGM), and now extends her research to the circumgalactic medium (CGM) using fast radio bursts (FRBs) and cosmic microwave background (CMB) Sunyaev-Zeldovich effect measurements. She actively bridges simulation work with observational data analysis and develops virtual/augmented reality tools for science outreach.

Education:

• PhD in Astrophysics, Harvard University

Dr. Wu's research focuses on high-redshift astrophysics, particularly reionization-era phenomena, IGM/CGM properties, and innovative observational techniques. Her methodology combines radiation-hydrodynamic simulations, analytic modeling, and observational data from instruments like CHIME. Current projects include FRB-based CGM mapping, non-parametric halo biasing models, and Pop-III reionization constraints via CMB. She also pioneers VR/AR applications for astronomy education, having learned Unity in 2022.

Her publication record reveals consistent contributions to leading astrophysics journals (MNRAS, JCAP, ApJ) with emphasis on methodological advancements in reionization modeling and CGM diagnostics. Key trends include exposing limitations of moment-based radiative transfer methods, demonstrating CMB constraints on Pop-III models, and developing stacking techniques for FRB-based CGM measurements.

No scientific awards are listed, though her research is published in high-impact journals and she collaborates internationally. As a postdoc, she focuses on independent research without current advising roles or publicly specified grant funding.

Dr. Wu operates within the Canadian Institute of Theoretical Astrophysics research ecosystem, contributing to open-source tools like Pyloser for mock observation generation. Her work involves extensive computational resources for simulations and data analysis, with collaborations spanning Harvard University, University of Arizona (Beijing-Arizona Sky Survey), and international telescope projects.
