Qianyi /tʃjɛn ˈiː/

I develop reliable and practical statistical methods for decision-making in complex systems.

I am a final-year Ph.D. student in Management Science and Engineering at the School of Economics and Management, Tsinghua University, advised by Prof. Bo Li. My research sits at the intersection of causal inference, machine learning, and uncertainty quantification.

Research

My goal is to build effective, scalable, sample-efficient, and easy-to-implement methodology for complex systems.

01

Causal inference

Experimental design, estimation, and policy learning for settings where complex interactions exist.

02

Uncertainty quantification

Conformal prediction with substantially improved conditional coverage.
