Alexander Thomas | Faculty
As a child growing up in the small town of Southwold on the eastern seaboard of the United Kingdom, Professor Alec Thomas thought he had discovered his calling in life.
"When I was 10, my father got me a chemistry set," he recalls. "I liked trying to understand nature at its most fundamental level."
However, his interest in chemistry took an abrupt turn when he discovered physics in high school and found he enjoyed the challenges of the field. He switched his focus to study physics, a change he credits for the development of his interest in plasma physics and nuclear fusion energy.
"I don’t like things to be easy," he says. "That is what led me to this field."
Despite the rigorous nature of his studies, Professor Thomas still found time to pursue other interests. During college, he played drums in a rock band called Calamari. At one point, the band was allegedly voted the second-best student band in London, with first place going to Coldplay. Although he recalls his rock band days fondly, he has little sentimentality for the quality of their music.
"I guess I would say we were alternative music in that we were the alternative to music," he jokes.
"I don't like things to be easy. That is what led me to this field."
His bandmates went into the banking industry in London, while Professor Thomas pursued a PhD in Physics. He then joined U-M as an assistant professor in the Nuclear Energy and Radiological Sciences (NERS) department. Professor Thomas studies the physics and applications of intense laser interactions with plasma and works within the Michigan Institute for Plasma Science and Engineering and the Center for Ultra Optical Science.
One particular area his research confronts is the miniaturization of high-energy particle accelerators using lasers. Current facilities demand a large amount of space to shoot charged particles at high velocities and allow for improved X-rays, effective radiation therapy and groundbreaking physics research. However, the high cost of construction limits their accessibility and use.
"If every hospital and university could have access to just one of these facilities in their basements, then that would be very useful," he says.
Professor Thomas also serves as the Undergraduate Program Chair for NERS. He is available for students to discuss course options and potential career paths—or talk about life in general. He encourages students to join the NERS department if they seek challenging scientific problems, a great breadth of research applications and the individual attention of a smaller department.
"The level of care given by the department is traditionally very high," he notes. "It’s a small department, so you’re not just an anonymous face in the crowd. You’re part of the family."
