Diesel Works

Stephen Diesel

An ecology of practices.

Product work is one practice among several. Each feeds the others, and each shows up in how I run product and operations.

01 / Research

Measuring the moving brain

Virginia Tech's Embodied Brain Lab, directed by Julia Basso, studies how movement, attention and creative practice show up in the brain. I've been a research scientist there since 2023, mostly hands-on.

Epiphany Machine

A neuroballet in which dancers perform while live EEG turns their brain activity into sound and image. I was on the research team throughout: I ran measurements, fitted performers with EEG caps and rigged the mobile EEG backpacks, contributed to the visualization code, and helped with the analysis that shaped its signal filters. I was backup performer for one of the on-stage researcher roles and helped run the performances. The work was covered in The New York Times.

Carving Out Creativity

A networked installation, shown in 2025 at four sites across Virginia: the Torpedo Factory Art Center and Virginia Tech's Innovation Campus in Alexandria, the Taubman Museum of Art in Roanoke, and the Cube at the Moss Arts Center in Blacksburg. Each kiosk paired a real carved stone with a virtual one. Touch the stone and you felt, through a haptic device, someone touching its twin at another site, while footage of the carvers, 3D scans of their stones and their brain activity, rendered as images and sound, surrounded you.

It grew out of a study of what stone carving does to the brain and to wellbeing. Twenty carvers from the Backyard Stone Carvers in Newport, Virginia, wore mobile EEG caps while they rested, did guided breathing, filed stone in sync with each other, carved, and critiqued the work, and answered wellbeing surveys before and after. I helped capture media during the sessions and helped with the carving sessions themselves.

I was first author on the draft paper behind our poster at the Society for Neuroscience meeting in 2024, which reported that carving improved mood, mindfulness and social connection, and increased synchrony between the carvers' brains. The full paper is in preparation, and I'm a co-author.

In the product work

Research keeps me honest about the difference between what we've observed and what we've assumed. A good hypothesis isn't evidence until it's been tested.

02 / Building

Building products myself

Two Trellis phone screens: the record screen, and a readout that quotes the teacher's own cues as evidence.

2026 · Own product · Founder, design and build

Trellis

Yoga teachers get detailed feedback during training and then almost none for the rest of their careers. Trellis is the app I designed and built to close that gap: record a class, get specific feedback grounded in what you actually said, and see how your teaching changes from one class to the next. Web, iOS and Android, in English and Spanish.

In the product work

Building my own product keeps my judgment honest: I feel every scoping call, and every shortcut comes back to me.

03 / Movement

Yoga and dance

Since 2017 · RYT-500, E-RYT 200 · More than 1,000 teaching hours

Classes, workshops and teacher training

I've taught vinyasa, power and heated classes since 2017, for most of that time at In Balance Yoga in Blacksburg, Virginia, where I trained, alongside Blacksburg Yoga Collective, Sweetgrass Yoga and classes for climbers at Crimper's Climbing Gym. Today I substitute at Threehouse Studios in Durham, North Carolina, and teach in community settings around San Juan.

Dance

Contact improvisation

I also dance, mostly contact improvisation: partners moving through shared weight and touch, improvising together.

In the product work

Teaching is attention: noticing what a room needs before anyone says it, and changing course mid-class.

04 / Arts

Music and live experiences

Sonic Forest: PlantWave showcase at Slingshot

Slingshot's organizer wanted PlantWave at the 2025 festival; I designed and produced what it became. A Sonic Forest of hundreds of plants across a 50 by 15 foot footprint in the warehouse at The Fruit, wired so PlantWave could turn their bioelectrical activity into live music. I built the partnerships with Durham Garden Center and the artists, installed the plants myself, and programmed the block: a talk on plant biorhythms from PlantWave creator Joe Patitucci, alongside plant-music sets from Bottlesmoker and Lightbath.

DJing

I've DJ'd since 2011, including music for specialty yoga classes.

In the product work

A live event is product work with no second take: partners, logistics and timing all have to land on the night.

05 / Community

Organizing people

Since 2022 · Board of directors · Christiansburg, Virginia

Downtown Christiansburg, Inc.

San Juan, Puerto Rico · Co-living house

Casa Chironja

A 15-bedroom co-living house and community space. I help run its administration and organize around six events a month: art days, lightning talks, La Sala (a series of intentional conversations), yoga and workshops.

Early 2010s · Blacksburg, Virginia · Organizer

Rock the Blocks

A two-night music festival across seven venues, with several thousand people and many genres. I handled logistics and partnerships with venues and advertisers, coordinated volunteers, booked talent, built the music and volunteer schedules, and managed the cash on the nights.

In the product work

Organizing volunteers and housemates is operations without authority: budgets, schedules and people who don't report to you.

06 / Coaching

Coaching builders

2026 · Executive coach

Waye

Waye, funded by the Human Rights Foundation, supports the people who build freedom technology. I coach a cohort of eight builders, HRF grantees and staff working mostly in the Bitcoin and Nostr ecosystems, in blocks of six sessions: product, leadership, hard decisions, and the personal side of all three.

In the product work

Decisions only stick when the person making them is ready. Coaching is where I practice that one to one.
