Hi, I'm Weixiang 👋

About Me

I'm a postdoctoral fellow at Bishop's University studying accretion onto supermassive black holes using multi-wavelength, time-domain observations. My work focuses on understanding how these extreme environments evolve, vary, and interact with their surrounding galaxies.

Beyond research, I enjoy developing open-source tools that support the broader scientific community, especially in astrophysics and data analysis. I’m also deeply interested in applying modern machine learning methods to large and multi-modal datasets --- bridging astrophysics and data science to uncover new insights.

Astronomy Research Interests

  • Time-domain/Multi-messenger astronomy
  • Accretion disk physics and black holes, massive black hole formation and evolution
  • Application of statistical and deep-learning techniques to astronomical data sets

Machine Learning Interests

  • Representation learning for multi-modal (time-series + imaging + spectrum + multi-wavelength photometry + ...) datasets
  • Time-series analysis of irregularly-sampled data
  • Uncertainty quantification
  • Scalable data processing for large sky surveys
