Welcome to my GitHub profile! I'm a Data Scientist and former Master Teacher with over a decade of experience at the intersection of education, policy, and data science. 🎓📊

I pronounce "Chrzan" as "chr" like chirp and "zen" like the state of mind.

I specialize in leveraging machine learning, predictive modeling, causal inference, and natural language processing to tackle real-world challenges in K–12 education and beyond. Currently, I work at the Center for Educational Data Science and Innovation (EDSI), where I focus on using AI to support equitable outcomes in teaching and learning, scenario modeling for school closure policies, and the ethical application of AI in education.

My journey has taken me through impactful research roles, EdTech environments, and hands-on teaching at K–12 and university levels. I’m deeply committed to using data science to create fairer, smarter educational systems.

• Projects applying AI and machine learning to improve educational equity 🎯
• Predictive models forecasting school closures and shaping policy 📈
• Natural language processing tools analyzing community feedback and educational data 🗣️
• Scenario generation algorithms to help schools make data-driven decisions 🔍
• Explorations on bias reduction in AI and ethical AI innovation ⚖️
• Research supporting strategic education policy and impactful EdTech products 🏫
• Repos related to fun side projects, like my Heart-of-the-Cards repo where I play around with some Yu-Gi-Oh! data

R, Python, SQL, PyTorch, Pandas, Tidyverse, PostgreSQL, deep learning frameworks, and statistical modeling techniques such as linear regression, IRT, and causal inference.

I've been working on improving my sfotware development and MLOps skills as well as wanting to learn more about Graph Neural Networks, Social Network Analysis, and Neuroeconomics!

• I was a Master Teacher and math instructor, mentoring future educators and designing project-based learning frameworks.
• I enjoy gaming—both video and tabletop—as well as diving into data simulation and AI bias reduction.
• I've been honored with awards including the Dean’s Fellowship at Stanford and scholarships like the Gates Millennium Scholarship and Coca-Cola Scholars.

Feel free to explore my repositories, where I share research projects, educational tools, and code that bridges data science and education as well as fun side projects. Whether you're an educator, researcher, policymaker, or fellow data enthusiast, I hope my work inspires and empowers you!
