Hi, I'm Rex

Curious about how the brain works, how healthcare gets built, and what's over the next pass.

I'm Theodore Rex Walrond, though almost everyone calls me Rex. I studied behavioral and cognitive neuroscience at the University of Florida, where I got hooked on research: working through hundreds of studies on how brain bleeds relate to Alzheimer's disease, and tracking COVID-19 drug candidates during the pandemic.

From there I moved toward the business side of healthcare and completed graduate coursework in finance at the University of Notre Dame. Today I'm focused on building an early-stage venture in consumer health.

Home base is St. Petersburg, on Tampa Bay. When I'm not working, I'm usually planning the next trip, out on the water, or over-analyzing my sleep data.

The path so far

A few chapters

Not a resume, just the parts that shaped how I think.

The lab years

Brains, bleeds & a pandemic pipeline

At UF's McKnight Brain Institute I synthesized 300+ studies on links between subarachnoid hemorrhage and Alzheimer's. Before that, a summer at Romark Laboratories building dashboards for 25+ COVID-19 drug candidates.

2021 – 2023
Giving back

Parkinson's support, one session at a time

As an Impact Partner with the American Parkinson Disease Association, I led a monthly support group of 15–20 people: planning sessions, bringing in guest speakers, and presenting.

2025 – 2026
Right now

Building something in consumer health

I'm putting my research background and finance training to work on an early-stage consumer health venture. More to share down the road.

Divemaster, University of Florida Scientific Diving

From 2020 to 2023 I helped teach scuba courses for UF's Scientific Diving Program, from Open Water through Master Diver: in-water skills, out-of-water skills, and classroom lectures on dive planning, physics and physiology. Most of my diving has been in Florida's freshwater springs.
