Xinyu Guo
I am a first-year PhD student at the University of California, Riverside, supervised by Prof. Holly O'Rourke. My research focuses on methodological innovations in quantitative and computational psychology and psychiatry, integrating causal inference and machine learning to extract reliable information from complex behavioral and clinical data and to develop tools that support rigorous scientific inference and decision-making.
我是加州大学河滨分校一年级博士生，导师为 Holly O'Rourke 教授。 我的研究聚焦于定量与计算心理学及精神病学中的方法学创新，将因果推断与机器学习相结合，从复杂行为与临床数据中提取可靠信息，并开发支持严谨科学推断与决策的工具。
Previously, I received my B.S. in E-commerce (Big Data) from Nanjing University of Chinese Medicine and my Master of Medicine from Sichuan University. I was a research assistant at the Hong Kong Polytechnic University, supervised by Daniel T.L. Shek.
此前，我于南京中医药大学获得电子商务（大数据）理学学士学位，于四川大学获得医学硕士学位。 我曾在香港理工大学担任研究助理，导师为 Daniel T.L. Shek。

Project 项目
Several projects that I lead are listed below:
以下是我主导或共同负责的部分项目：
Project Description
I directed the 5th wave of the survey, including coordination with participating schools and logistical planning and managed field surveys, data entry using Epidata, and ensured accuracy in preliminary data processing.
I independently conducted data matching, screening, cleaning, and missing value imputation for Waves 1-4, then developed a longitudinal machine learning model to predict adolescent NSSI, published in Journal of Affective Disorders, 2025.
Project Description
I co-led the 2023 Sichuan Province survey team, with responsibilities including project planning and coordination, field household interviews, and software management.
I led a chronic disease and health literacy survey across 7 Sichuan Province cities, organizing field data collection and interviews, analyzing and visualizing results, and preparing the research report for government departments.
