About

Hi there! I am Yu Dong. I am a detail-oriented data scientist and storyteller. I graduated from MS Business Analytics program from USC Marshall School of Business in Dec 2017. After graduation, I worked as a product analyst at Ancestry.com for three years, using analytics to understand user behavior, improve product engagement, and enable data-driven business decision-making. Then I joined Brex as a Data Scientist in late 2020, exploring more analytics and data science application in the fintech industry. I am passionate about interepreting data under business context and data-driven business decision-making.

I’m also a lifelong learner with deep curiosity. I have completed more than 30 online courses on Coursera, edX and other MOOC platforms in subjects ranging from Statistics to Machine Learning.

Outside work, I make one data visualization on Tableau Public every week since 2018. You can find my collections here.

My analytical skillset includes:

• Data mining: R, Python, Spark (in Scala and PySpark), Excel
• Visualization: Tableau, R Shiny
• Databases: MySQL, Amazon Redshift, Snowflake
• A/B Testing and Causal Inference
• Machine learning models
