I think about energy.
Specifically: how we can store it and how we can use less of it to make the things (particularly metals) we need. Regardless of what you might have heard, using less energy is a good thing, and using less energy and doing so within thermodynamically closed systems is an even better thing.
I work [here](https://columbia.edu), specifically [here](https://ceec.engineering.columbia.edu) under the frameworks of [this](https://eee.columbia.edu/) and [this](https://cheme.columbia.edu).
I used to work [here](https://princeton.edu), after working [here](http://ccny.cuny.edu), after working at a few places that no longer have websites. Poof.
I'm directly responsible for [this](https://feasible.io) and to a lesser extent [this](https://voltaiq.com), and I am proud to be indirectly responsible for [this](https://imprintenergy.com) and in the same rolodex as [this](https://silanano.com/leadership-team/).
