Designing 240-metre towers at SOM taught me how complex systems actually get delivered — and exactly where their assumptions run out.

Five projects across three continents taught me that the boundary between 'how it's always done' and 'what the problem actually requires' is where the most interesting work lives. At SOM, the only way to push the boundaries was to prove it — quantifying every unknown until the unconventional became undeniable.

How I work

Working without defaults demands a method. This is mine.

01

Let the problem surface the solution

Start with what the problem actually requires, not what the standard says is good enough. Rules are written for common cases. Interesting problems rarely are.

02

Build the tool if it doesn't exist

When the right tool doesn't exist, build it. Problems at the edge of what's been done before usually need methods that don't exist yet.

03

Work across the full stack

Don't hand the problem off at the boundary of your discipline. The most important insights usually live at the interfaces.

04

Quantify what you don't know

Pushing the boundaries means working with uncertainty. Measure it, bound it, and make explicit decisions about what's acceptable.

Selected Work

Five projects. Five moments where the default answer wasn't good enough.

What it made me

The projects are specific. The lessons aren't.

01

I think in systems, not in components.

A complex problem is never a local exercise. If you want to solve the system, you need to see it in all its complexity. That's how I learned to always step back and see the whole.

02

I'm comfortable where a wrong assumption has real consequences.

When you work on real, tangible things like a building, you develop a different relationship to uncertainty. You learn to quantify it, work with it, and make decisions despite it rather than pretending it away.

03

I've learned to be a beginner on purpose.

The most interesting problems sit just past the edge of what you know. Getting there means being willing to start from scratch. I've made that choice more than once. It's never felt wrong.

I'm looking for the next hard problem. If that sounds like yours — let's talk.
