Engineer, founder & operating leader

I’m Tei Newman-Lehman

I’ve been drawn to building physical systems for as long as I can remember—starting in my family’s garage, where I built a gas turbine from scratch and a working distillation column using laboratory glassware my uncle brought over from his job at the Salk Institute. That curiosity carried me through Engineering Science and nuclear engineering coursework at UC Berkeley and into a sixteen-year career designing scientific instruments, scaling manufacturing operations, and building companies from the ground up.

Outside of work, I live with my wife, Jasmine—a chemical engineer—and our three rescue dogs (two Belgian Malinois and a husky: Suzi, Mina, and Halo). Around our house, the running joke is that Jasmine supplies the vision and I figure out how to build it—whether that means renovating our hillside home, building a tree-house patio under the pine tree, or heading out into the backcountry for field geology and trail hikes.

Architecture and home

Watching Visual Acoustics, the documentary about architectural photographer Julius Shulman, got me hooked on mid-century modernism, and Pierre Koenig’s Stahl House—Case Study House No. 22—became the central inspiration for the renovation of our home in San Diego.

Before touching a wall, I drew plans and built physical scale models to test how different room, kitchen, and multi-level deck layouts sat on the slope. After working alongside architects, contractors, and lighting designers on the structural remodel, Jasmine and I still treat the property as an ongoing design-build project—from building an elevated patio under our pine tree for Friday nights to spending weekends on woodworking, courtyard drainage, and leveling brick pavers.

The gallery includes early models, photographs from the renovation, the finished rooms, and the deck at sunset.

The house is available for photo and film shoots.

A road trip through the American West

I really love a good road trip. During COVID, I spent four months on the road and drove 5,800 miles across the American West—from snow on the rim of the Grand Canyon and two-lane red-rock highways in Utah to wild turkeys wandering down a snowy sidewalk in Montana. The coastal stretch from Arcata down to Big Sur was hands down the most picturesque part of the drive, and passing through so much Western water infrastructure along the way sent me down a deep rabbit hole on California watersheds and the engineering history of the Colorado River.

Geology and prospecting

Spending time in those landscapes sparked an ongoing interest in field geology and mineral prospecting—using public geological surveys and mapping data to pick formations to explore on foot, from backcountry canyons at Dinosaur National Monument with Jasmine to granite trails in San Diego’s East County near Julian with Suzi, Halo, and Mina (usually followed by pizza and apple pie in town).

Whenever Jasmine and I travel through cities instead, we trade trail maps for modern art museums, heavy-music shows, vintage clothing shops, and a running effort to track down the best pizza—a field study now roughly fifty cities deep.

A few things I’ve saved

I have a long-standing soft spot for deadpan New Yorker cartoons—especially where over-engineered science, nature, and everyday domestic life collide—and a habit of saving lines I want to come back to.

Years ago, when Jasmine and I worked at the same company and she walked past my desk twelve times a day for coffee without looking up, I started pinning a rotating set of esoteric New Yorker cartoons along her path. After two weeks, she finally stopped to ask what one of them meant—and after our first walk to get coffee, where she told me about an obscure protein called Suckerin from her PhD research, I went home that night and created the first Wikipedia article on Suckerin ↗ citing her work.

Lines I keep around

  • “A pessimist is a person who has had to listen to too many optimists”

  • “Sometimes the road less travelled is less travelled for a reason.”

  • “Artificial intelligence is no match for natural stupidity.”

  • “My opinions may have changed, but not the fact that I am right.”

  • “To be sure of hitting the target, shoot first and call whatever you hit the target.”

  • “To err is human, to blame it on somebody else shows management potential.”

  • “I don’t have a solution, but I do admire the problem.”

  • “The journey of a thousand miles begins with a broken fan belt and a flat tire.”

  • “If you don’t care where you are, then you ain’t lost.”

  • “The truth is rarely pure and never simple”

  • “Money can’t buy happiness, but it sure makes misery easier to live with”

Experience you can explore

Engineering and product development

I’ve designed mechanical, thermal, and electrical hardware for scientific instruments and experimental rigs—using SOLIDWORKS, finite element analysis, and flow simulation to evaluate designs before building them. I’ve also built LabVIEW control and measurement tools, integrated multi-instrument workcells, and led safety certification for commercial launch.

Commercial strategy

I work out which customers have an urgent reason to buy, what proof they need, and how their institutions actually purchase—connecting positioning, scientific marketing, unit economics, direct sales, and global distribution agreements.

Company and team leadership

I’ve founded and bootstrapped companies, raised seed funding, and recruited multidisciplinary teams across engineering, science, and sales. At Eton Bioscience, I stepped in as General Manager and ran the multi-branch laboratory-services business cleanly through its sale while keeping customers served.

Career

Several roles overlapped.

2021–2024

Director of Engineering Innovation, 2021–2022; Senior Director of Oligo Synthesis, 2022–2023; General Manager of Telesis Bio’s Eton Bioscience subsidiary, 2023–2024.

2018–2021

Co-founder & founding CEO; remained on the board through January 2023.

Education

B.S. in Engineering Science, UC Berkeley, 2008.

  • Optical array qPCR — published US patent application, 2023; optical monitoring of biological reactions.
  • Four filed provisional patent applications for Piezolith processor power-delivery and cooling architectures, plus drafting and filing Mimulus’s first provisional patent application.

Scientific work

At UC San Diego, I designed the equipment and automated experiments used to investigate flame behavior. I contributed to publications and conference presentations, with scientific collaborators contributing interpretation and numerical modeling.

  • The structure and extinction of nonpremixed methane/nitrous oxide and ethane/nitrous oxide flames — Proceedings of the Combustion Institute, 2013 volume; published online in 2012.
