I am a CosmicAI Postdoctoral Fellow in the Department of Statistics and Data Sciences at The University of Texas at Austin and the NSF-Simons AI Institute for Cosmic Origins. I work with Prof. Alessandro Rinaldo and Prof. Arya Farahi in the Explainable Universe working group. My research focus on simulation-based inference, nonparametric methods, optimization, and Bayesian inference, with an emphasis on new methodological advances that enhance the transparency, rigor, and reliability of AI systems for scientific discovery.

I obtained my PhD degree in the Department of Statistics at the University of California, Irvine. I work with Prof. Michele Guindani (now at UCLA) and Prof. Weining Shen (UCI). I have been working with Prof. Federico Camerlenghi and Prof. Mario Beraha since my visit to the Department of Economics, Management and Statistics at the University of Milano-Bicocca in Milan, Italy, in 2025. I am also working on a project in collaboration with Prof. Falco J. Bargagli Stoffi (UCLA).

During PhD study, my research interests include Bayesian methods, Bayesian nonparametrics, random partition models, random measures, point processes, repulsive mixture models, spatio-temporal and functional data analysis, causal inference, and biomedical applications. ` `
