👋 Welcome!

My name is Jiahao Tian. I am an undergraduate student majoring in Statistics at the School of Mathematical Sciences, Zhejiang University (ZJU).

Prior to this, I was selected for the Chu Kochen Honors College (Physics). Driven by a profound passion for rigorous theoretical foundations, I transferred to Statistics to pursue strict mathematical training. My coursework and self-study heavily concentrate on advanced pure mathematics and measure-theoretic probability. Currently, my research focuses on high-dimensional statistical inference, distribution-free prediction, and their theoretical robustness.


🔍 Research Interests

  • Core: High-Dimensional Statistical Inference, Conformal Prediction, Statistical Learning.
  • Extended: Stochastic Analysis, Bayesian Inference, Quantitative Finance.

🛰️ Research Experience

Robustness of Multiple Knockoff Aggregation Methods

  • Advisor: Prof. Lijun Wang, Zhejiang University. (Sept. 2025 – Present)
  • Systematically evaluated the robustness of state-of-the-art aggregation methods (e.g., e-value, based-voting, MDS) under extreme heavy-tailed noise and high collinearity. Diagnosed failure mechanisms within thresholding steps and explored empirical CDF approximation frameworks to dynamically calibrate selection power.
  • Status: First-author manuscript in preparation.

Uncertainty Quantification via Conformal Prediction

  • Advisor: Prof. Guanhua Chen, UW–Madison. (Mar. 2026 – Present)
  • Investigating conformal inference frameworks to construct distribution-free and covariates shift predictive intervals for complex statistical models.

🎤 Academic Talks

  • Convergence of Random Series and Large Deviations (Fall 2025) Delivered a 120-minute lecture in the Advanced Probability Theory Seminar, focusing on rigorous proofs of limit theorems and large deviation principles.
  • Robustness of Multiple Knockoff Methods (Fall 2025) Presented a comprehensive review of Model-X and derandomized knockoff procedures at the Weekly Statistical Seminar.

📚 Academic Garden

Beyond my research, I maintain a detailed, open-source collection of course notes and rigorous mathematical derivations (e.g., Stochastic Differential Equations, Asymptotic Statistics).


📮 Connection

I am always open to academic discussions and collaborations.
