01 / SELECTED WORK精选项目

Questions worth answering.从实际问题出发。

A selection of business, product, and research problems I have worked on.围绕商业、产品与研究问题，展示我的分析方法与贡献。

01PRICING ANALYTICS定价分析
$130Kpricing gap across 3 flagged orders3 笔异常订单的合计定价差额

GE Motors by Wolong · 2025

Finding the signals in pricing.发现定价中的异常信号。

Used regression and segmented visualizations to investigate OEM versus distributor pricing across states, product divisions, and volume tiers.用回归模型与分组可视化，分析不同州、产品部门和销量区间中 OEM 与经销商的价格差异。 The goal was to make unusual orders easier to spot and explain, then connect those findings with clearer pricing information and review workflows.目标是让异常订单更容易被识别和解释，并将分析发现与更清晰的定价资料和审核流程衔接起来。

The question业务问题

Which orders deviate from expected pricing after accounting for customer channel, geography, product, and volume?在考虑客户渠道、地区、产品及采购量之后，哪些订单的价格仍显著偏离预期？

My contribution我的工作

Built a regression model in R, used faceted boxplots to compare segments, and presented three underpriced orders with a combined $130K gap to leadership. Also restructured pricing files containing 40+ technical fields and developed a multi-level sales approval workflow in Power Apps.在 R 中建立回归模型，以分面箱线图比较各业务分组，向管理层汇报 3 笔合计约 13 万美元定价差额的低价订单。同时整理包含 40 多个技术字段的价格文件，并通过 Power Apps 搭建多级销售审批流程。

The pricing gap identifies an opportunity for review; it is not a claim of realized savings.该差额代表识别出的定价问题，不等同于已实现的节省或追回收入。

02PRODUCT ANALYTICS产品分析
190K+user behavior records analyzed条用户行为记录

WeFIRE · 2024–2025

Understanding what users do next.理解用户行为与转化。

The approach分析方法

Cleaned and explored 190,000+ records, engineered features, and built a Random Forest classifier. The reported evaluation reached 74% accuracy and 84% recall. Identified an attribute associated with approximately 3× higher activity.清洗并探索 19 万多条记录，开展特征工程并建立随机森林分类模型。项目记录的评估结果为 74% 准确率、84% 召回率；识别出与约 3 倍活跃度相关的用户特征。

Beyond the model模型之外

Researched six competing products, with a focus on AI capabilities, and worked with Product and Engineering to communicate user pain points through data visualizations.研究 6 款竞品，重点关注 AI 功能，并通过可视化与产品和工程团队沟通用户痛点。

The activity relationship is an association, not a measured causal lift.活跃度差异为相关性发现，并非实验验证的因果增长。

03HEALTH & MACHINE LEARNING健康与机器学习

Competition overview竞赛介绍

Competition research; not a clinical deployment. The link describes the competition, not an individual leaderboard profile.此项目为竞赛研究，并非临床部署。链接为竞赛介绍页，而非个人成绩页。

Studying econometrics and statistics gave me complementary ways to approach data: understanding the economic question and choosing methods that can answer it. Coursework included statistical modeling, probability, statistical programming, and financial econometrics. Research, ATLAS internships, and teaching roles helped me apply that foundation beyond the classroom.GPA 3.98 / 4.00，所有学期均获院长荣誉名单。计量经济学与统计学提供了互补的分析视角：既理解经济和业务问题，也选择能够回答问题的方法。课程包括统计建模、概率论、统计编程及金融计量经济学；研究、ATLAS 实习和教学工作则让我把课堂基础应用到真实场景中。

Statistical Modeling统计建模课程

STAT 425 Course Assistant · UIUCSTAT 425 课程助教 · UIUC
Aug – Dec 20252025.08—12

Supported instruction in statistical modeling by evaluating assignments, exams, and applied projects in R. I gave detailed feedback on regression assumptions, diagnostics, model selection, reproducibility, and the interpretation of coefficients. Working with the instructional team also strengthened my ability to explain why an analytical approach is appropriate, rather than only whether the calculation is correct.通过评阅作业、考试及 R 应用项目支持统计建模课程教学，针对回归假设、诊断、模型选择、可复现性和系数解释提供详细反馈。与教学团队的合作也锻炼了我的分析表达能力：既判断计算是否正确，也说明分析方法为何适合当前问题。

Economics Tutoring经济学辅导

Econ Tutoring Center · UIUC经济学辅导中心 · UIUC
Aug – Dec 20242024.08—12

Supported students in economics coursework through individual tutoring. Helping someone work through an unfamiliar problem required patience, clear explanations, and a willingness to approach the same idea from more than one angle. This experience complemented my analytical training by giving me regular practice communicating technical concepts at different levels of familiarity.通过个别辅导帮助学生学习经济学课程。带领他人理解陌生问题，需要耐心、清晰表达，以及从不同角度解释同一个概念。这段经历与我的分析训练相互补充，让我持续练习向不同基础的听众传达技术概念。
