Chaoyun Bao (UMN Physics PhD)

Managing strategy consultant for IBM

Picture of Chaoyun BauChaoyun has been interested in science for her entire life and was fascinated by images from the Hubble Space telescope as a child. She chose to be an astrophysics major because of an inspiring professor and went to the Iowa State University for graduate school. She later transferred to the U so she could work on cosmic microwave background research. After working at the U as a postdoc for a year, she moved to the private sector.

“I decided to leave academia because I wanted a bigger audience to what I do – there are probably 20 people in the world who could understand the papers I published during my PhD.”

She began working in data science, solving problems in the energy industry. Finding that she lacked necessary business acumen, Chaoyun got a Tech MBA at NYU Stern. She now works at IBM in the Chief Analytics office.

“My physics background definitely gives me the credibility of being a critical and analytical thinker, as well as a problem solver … Even though most of my general relativity or quantum mechanics knowledge won’t be used in my day-to-day work, it gives me the confidence that I have the capability to learn and understand any complex technology or concepts needed

for my job.”

Staff Scientist, Los Alamos National Laboratory

Picture of Ian Tregillis

Ian’s first experience doing physics research came in his senior year of high school, when he was able to work with a professor at the U building circuits. He continued at the U and had multiple research experiences in both solid-state physics and computational astrophysics. Enjoying astrophysics, he chose to double major. It became the focus of his senior thesis as well as his graduate studies, also at the U.

“I worked on numerical simulations of "cosmic bullets:" clumpy supernova ejecta traveling supersonically through a gaseous background medium. I enjoyed computational astrophysics, and this determined my path for the next decade.”

After earning his PHD Ian took a post-doctoral position at Los Alamos National Lab (LANL), eventually becoming a permanent staff scientist. He currently works on nuclear fusion projects.

“To this day, I am endlessly fascinated by the way physics illuminates how the world works at a very fundamental level. Being fluent in the mathematical language of physics enables a person to make meaningful quantitative predictions about the world. It is extremely satisfying to work through a physics calculation from first principles to predict a measurement, then later see that prediction confirmed by experiment.”

Maribel Núñez Valdez (UMN Physics PhD)

Researcher at Helmholtz-Zentrum Potsdam

Professor at Goethe Universität Frankfurt am Main

Maribel Núñez Valdez (Physics PhD)

As teenager, Carl Sagan’s “Cosmos” got Maribel hooked on the stars. An internet search into what was required to be an astronomer set her on the path to getting her undergraduate degree in physics.

“I was always trying to understand why things in nature work or happen the way they do and not another.”

As she took her undergraduate classes, Maribel’s interest shifted to theoretical physics. She moved to Minnesota and earned her MSc and PhD doing work first in particle and later in condensed matter physics.

A supportive postdoctoral advisor at ETH-Zürich gave Maribel a “professional energy boost” and the confidence to continue along the academic career path. She currently holds a research position in the physics and chemistry of geomaterials at Helmholtz-Zentrum Potsdam in Germany, and she is a professor at Goethe Universität Frankfurt am Main. She enjoys teaching courses tailored for non-physics majors, and mentoring students. Her physics journey has now brought her all over the world, and through many different subjects.

“It was neither straight nor easy path from astronomy to the atomic world, but ultimately I feel a sense of accomplishment for that little girl from Mexico that experimented with thermometers in the kitchen and watched the night sky.”
