Passionate about Open Source

Accessible Open Education

I have 20+ years experience in designing technical training that tackles the hardest technical pain points—equipping scientists with the skills to work openly, reproducibly, and collaboratively. I have built over 300 open lessons for workshops, bootcamps, and semester-long courses at Universities and non profit organizations.

Community Matters Most

I have spent the last 9 years, creating and nurturing a vibrant scientific open source community of practice from the ground up—building the human infrastructure needed to ensure open science practices thrive. Helping people is at the heart of all of my work.

Open Source Steward

I am passionate about open source whether it’s Python, R or javascript, I love it all. At pyOpenSci we run an open peer review process to improve scientific software.

I maintain:

I also enjoy rebuilding maintainer teams.

On Being Named a PSF Fellow

I found out a few weeks ago that I’ve been named a Python Software Foundation Fellow. The news came in an email. When I read it, my eyes teared up. I wasn’t quite expecting such an honor. I felt this odd mixture of deep gratitude and surprising discomfort. Gratitude Being named a PSF Fellow recognizes the work I’ve poured years into building pyOpenSci—creating structures for open source peer review, training hundreds of researchers, and fostering a welcoming, inclusive community.

Python's Reproducibility Crisis: And How We Fixed It for Open Science Education

The problem nobody (or everybody?!) talks about We obsess over reproducible analysis, version control, and open data. But there’s an earlier barrier that kills scientific momentum before research even begins: installation friction. If a scientist can’t install your tools, your open science dies on arrival. And the same is true for open education lessons and tutorials, too. I learned this the hard way when I switched from R to Python while building data science education programs.

Using YouTube to Make Remote Sensing Data Accessible to Ecologists

The Challenge At the National Ecological Observatory Network (NEON) I built their NEON Data Skills program. Here, I faced a fundamental problem: ecologists weren’t ready for “big” data. NEON, funded by the National Science Foundation is an effort to build and now operate over 50 research sites across the United States. The data collected by NEON are massive and complex. But they also empower ecologists to use long-term, standardized datasets to track changes in our environment over many decades.
