Zhenyu (Zach) Wang 王振宇

Ph.D. Candidate in Statistics · Rutgers University

I am a fourth-year Ph.D. student in Statistics at Rutgers University. My research focuses on distributional robustness, causal inference, and non-regular statistical inference. I have the privilege of being mentored by Prof. Zijian Guo and Prof. Yifan Hu. Before my doctoral studies, I completed a Master's degree at Columbia University and earned my Bachelor's degree in Finance from Shanghai Jiao Tong University.
