Hi! I’m Landon Lehman, currently a data scientist at Splitwise. I was previously a Clinical Assistant Professor of Physics at SUNY Buffalo, and before that completed my physics PhD at the University of Notre Dame.

Download my resume (pdf) for more background, or my CV (pdf) for a list of my publications.

I do some consulting work, though my availability varies. Some of my skills that you might find useful:

- Exploratory data analysis and visualization
- A/B testing
- Statistical modeling
- Writing, editing, and research, especially for technical or scientific topics.
- Performing detailed calculations and providing necessary math or physics background for specific projects.
- SQL, R, and Mathematica programming and troubleshooting

Please contact me if you would like to discuss further and find out if I am the right fit for your project or company.

Disclosure statement: I am an employee of Splitwise. This is my personal blog. The opinions expressed here represent my own and not those of my employer.
