In 1990 I started my PhD in Biomedical Engineering at Duke because an undergraduate experience had taught me that I love research. As I dove into my graduate work I found that I was drawn towards something else... I wanted to invent solutions, not just study problems.
In the early 2000's a collaboration between UVA and PocketSonics led to the development of one of the very first hand-held ultrasound imaging systems - the Sonic Window. It was a beautiful product and while PocketSonics was acquired, the Sonic Window didn't last long in the market. I got some satisfaction from invention, but the lack of patient impact was a deep disappointment.
Around the time that PocketSonics was founded, Michael Lawrence challenged me to use ultrasound to understand clotting. With Francesco Viola the three of us founded HemoSonics. It was a long road, but we had great luck at the right times. We received key investment from the NIH and the Wallace H. Coulter Foundation. Bill Brown provided the first capital to get the concept out of the University of Virginia. Dr. Mark Wheeler invested a year later and I left the safe world of tenured Professor with the goal of making a product that would save lives. Megan Kahn Shaw joined us early in our corporate life and we built an exceptional engineering team including Timothy Higgins, Aaron Buchanan, and Andy Homyk.
It was a long process. We had an early partnership with StarFish Medical that helped me understand that Technology is not Product. Later we partnered with Key Tech Inc. to finalize the product. Along the way we hit a existential crisis when data demonstrated that the core technology was not precise or accurate enough to address our clinical problem. In a three month period I worked with Scott Corey to invent a new measurement technology that became the core of the Quantra. In 2017 Stago acquired HemoSonics and has made our invention an impactful product.
I was gratified last night when I found that TIME named the Quantra System one of the best inventions of 2024.
I have lived the dream of every engineer. I invented something that helps real people. I can never properly thank all the people that contributed, but I am profoundly grateful for the many layers of support that I've received.
