My research interests center on ML for inverse problem and sparse reconstruction, ML-driven methods for numerical computation and physical field simulation, and multiphysics. I am also interested in embodied intelligence and robotics.

I continue to collaborate with the CAB Lab at Princeton University following my exchange there in spring 2026.

OrbitRIR: Frame-Averaged Few-Shot RIR Synthesis for 3D Sound Source Localization

Yixun Hu, Zhixuan Zhao, Tao Zhong, Christine Allen-Blanchette

OrbitRIR uses frame averaging to enforce receiver-yaw invariance in few-shot room impulse response synthesis and supports 3D sound source localization through analysis-by-synthesis.

Project PDF will be released soon.

Advisor: Prof. Christine Allen-Blanchette Mentor: Tao Zhong

  • NeTMY: Led physical modeling and neural-field design (Feb–Jul 2026) for sparse NV-center reconstruction, studying forward-model fidelity and center-collapse mitigation; continued collaboration on equivariant models for acoustics and weather forecasting.
  • LCG-SFNO: Collaborated with Yaojun Li to extend SFNO using Clebsch–Gordan (CG) tensor products, achieving full SO(3) equivariance and improving weather forecasting accuracy. Led the design of SSHCG, a CG tensor-product computation library that reduces computational overhead and model deployment costs.
  • OrbitRIR: Collaborated with Yixun Hu to improve acoustic modeling through frame averaging and receiver-yaw invariance, increasing RIR synthesis accuracy and improving sound-source localization in unseen rooms.

Advisor: Prof. Xianghua Xu (徐向华)

I developed a CNN surrogate to infer cell-wise correction coefficients from temperatures on two opposing surfaces, addressing non-orthogonal mesh errors in finite-volume heat-transfer simulations. I led the implementation, including ANSYS mesh parsing, and benchmarked the model against least-squares-based methods on simple 3D geometries.
