# R&D Engineer, Advanced Development @ 24M Technologies

Period: July 2016 to early 2018

Technical lead on a $3.5M ARPA-E battery program, translating electrochemistry into product decisions that had to hold up on a real roadmap.

The first place where a result I cared about was not real until the rest of the business agreed it was.

At 24M I worked on advanced battery development and was technical lead on the ARPA-E IONICS project, a $3.5 million Department of Energy grant focused on high-energy-density batteries. It was a continuation of the battery work I had started at Princeton, but now with commercial constraints turned all the way up.
The work covered active and inactive material evaluation, electrode and electrolyte specification, cell design testing, root-cause failure analysis, and cost optimization. It was the first time I had to carry technical judgment through manufacturability, budget, and schedule instead of stopping at the lab result.
That changed how I thought about science: not just whether something works, but whether it can survive contact with reality.
