Neuroscientist & Investor
Tim Fergestad
I apply scientific thinking to investing and decisions under uncertainty.
I spent years in molecular neuroscience before moving into private markets. What transferred was not the subject matter. It was the habit of treating every claim as a hypothesis, including my own.
I write about how that discipline changes the way we invest, evaluate people and opportunities, and make decisions when the future is unknowable.
What I write about
Every investment is a hypothesis
Name the assumptions, look for confounders, decide in advance what would prove you wrong, and build a process that still works when you are.
From earning to owning
High achievers are trained to earn. Durable wealth requires learning to own and allocate. Income creates capacity; ownership creates optionality.
Start with the operator
A projected return is an output. The people, the incentives, the structure, and the downside are what produced it, and they are where the work belongs.

Five questions I ask before I commit to anything, and the control experiment that taught me to ask them.
Background
The short version
I earned a Ph.D. in neuroscience at the University of Utah School of Medicine and spent my research years studying the molecular machinery that allows one nerve cell to communicate with the next, later continuing that work in the Genetics Department at the University of Wisconsin-Madison.
While I was a scientist, I was also building a life outside the laboratory through real estate and investing. I bought and renovated properties, owned rentals in multiple states, worked in land and residential real estate, and gradually moved into larger private investments. As that portfolio and my opportunities grew, I transitioned out of academic research and increasingly focused my capital and attention on ownership.
Over time, that evolved from single-family real estate into multifamily syndications, private credit, preferred equity, development, and other private-market investments. Today I run Oak Street Assets, a boutique investment firm through which I invest alongside accredited investors in opportunities I believe merit our capital. I also host the Phoenix Prosperity Podcast.
One of the benefits of that transition has been greater control over my time. I still take investing seriously, but I am no longer interested in being busy for the sake of being busy. Capital should ultimately serve a larger purpose: freedom, family, legacy, and the ability to live greatly.
My scientific background also keeps me interested in the intersection of private capital, healthcare, biotechnology, and the life sciences. For now, that is an area of study and relationship-building, not a claim of investment expertise. My core investment work remains grounded in assets and strategies where I have experience, conviction, and the ability to evaluate the downside.
