From One Terminator to Twelve Years of Building DNA
When I was a postdoc at Stanford, I was using synthetic biology to study host-pathogen interactions — engineering circuits in E. coli and lambda phage. To build them, I could scavenge most of the parts I needed from colleagues’ plasmids (not a lot of fun, if you’re familiar with the chaotic organization of academic -80°C freezers) and stitch them together using the then-new technique of Gibson Assembly. But there was one terminator nobody had. So in 2012, I ordered my first piece of synthetic DNA from IDT. A 150-base pair double-stranded fragment. It took six weeks.
That experience stuck with me. Soon after, I convinced Dan Gibson to hire me as a Scientist in his group at the Synthetic Genomics Institute. I joined in early 2013 to work on booting up synthetic genomes in a tube, but three months in, the mission shifted. SGI decided to commercialize its underlying DNA synthesis technology, and I volunteered to help launch the new business unit with a simple pitch to Dan — “Send me anything the team can’t build.”
One problem kept showing up. Shorter-than-expected PCR products with the correct ends. Once bad oligos were ruled out, I had a hunch — internal sequence repeats that the design tools weren’t screening for. One late night, I BLASTed a problem sequence against itself. The alignment lit up with a repeat that, when the intervening region deleted out, produced exactly the artifact the team was seeing. That was my first sequence complexity tool, and I was hooked on building DNA.
Over the next twelve years, I grew alongside the industry. From those early “impossible” builds to scaling a services operation to $8M in revenue, project-managing the first GMP facility making synthetic DNA for cancer immunotherapy, launching new product lines, and building business models for next-generation synthesis platforms. I’ve worked across the entire value chain, from the bench to corporate strategy, and that’s given me a perspective that’s hard to get any other way.
The industry has changed enormously since that six-week terminator. Plasmids that took me three months as a postdoc now arrive in days. But what I find most interesting right now isn’t just that the technology is advancing — it’s that the technology is diverging. Array-based synthesis is driving scale and cost down for high-diversity applications. Enzymatic approaches offer a path to greener chemistry, complex sequences, and on-prem manufacturing. Traditional phosphoramidite chemistry still anchors the bulk of production. And then there’s the assembly layer on top — different technologies for predictably stitching fragments into larger constructs, each with its own tradeoffs. These aren’t competing to be the one winner. They fit different product-market needs, and understanding which technology belongs where is where technical depth and product strategy meet.
That’s where I’m focused now. I’ve moved on from that chapter with an end-to-end perspective on how DNA gets designed, built, and delivered. My goal is to make sure the products and business models evolve as fast as the science behind them.
