“Ask the right questions, step outside of comfort zones, make friends in strange places and take risks. And when outcome doesn’t match expectation, treat it as a learning opportunity.”

–David Wark

Adventure. For David, that could be pursuing a number of sports. Trying to keep up with his teenagers. Or working on a restricted GE Global Research project that can’t be discussed.

Change Is Good

With degree changes from engineering to oceanography to geosciences, and academic studies that encompassed oil reservoirs, volcanoes and the transport of fluid in the deep earth, David has followed curiosity wherever it led. Most recently, he moved from the geosciences to work on high-temperature alloys—but then returned to his roots, and now applies rare skills as a “turbine geologist” to mineral dust ingestion in gas turbine systems.

Bold Inquisition

Even less-than-amazing results from an experiment testing the processes in magma chambers beneath volcanoes have inspired David to continue asking questions and testing theories. One of them, a technique to measure temperatures (post mortem) of crystals growing inside magma chambers, is widely used today.

However, “I’m awaiting invention of cold fusion turbines. Once we have this technology perfected, I suspect mineral dust ingestion won’t be a problem,” David says. “I’ll just have to go back to work as a geologist—perhaps exploring for natural sources of the element Palladium.”
