Daniel's GitHub Header

I'm Daniel, a researcher at UC Berkeley and Lawrence Berkeley National Laboratory working where chemistry meets data science. I build machine learning and high-performance computing tools to take on hard problems in climate science and sustainable energy systems.

My curiosity also runs into nuclear science, green chemistry, and astrochemistry!

What I care about most is using computation to turn difficult scientific questions into working solutions, and carrying that work into the places where science actually meets the world.

Other things about me!

Favorite molecules by category:

⌬ Organic ⬡ Inorganic ⚛ Organometallic
Vanillin Plutonium(III) chloride Uranocene
It's what gives vanilla products their smell and taste! I love the tricapped trigonal prismatic geometry, and it's a green crystalline compound! It glows my favorite color, green, and contains my favorite element, uranium!

Beyond the lab:   I paint, work with ceramics, and draw, and I love turning complex ideas into colorful visualizations that actually click for the people I share them with. If there's a way to make something more colorful, I'll find it.
