Adler Planetarium Leadership & Executive Team

Michelle Larson - President and CEO

Michelle B. Larson, PhD

President and CEO

Michelle Larson attributes her career path to looking up, literally. Growing up in Alaska she enjoyed the beauty of the Northern Lights, and she became further captivated by astronomy in her 20s when she pointed a pair of binoculars at the Moon. The stunning details visible on its craggy surface were a complete surprise, and the experience left her eager to explore what other secrets the cosmos had to offer. Now, as the President and Chief Executive Officer of the Adler Planetarium in Chicago, Michelle leads a talented team that connects people to the Universe and each other under the sky we all share.

Since Michelle joined the Adler Planetarium in 2013, that team has found new and innovative ways to meet people wherever they are and welcome them into the scientific community. The museum has expanded programming and partnerships in neighborhoods across Chicago; developed a live lecture series that projects stunning data visualizations onto planetarium domes around the world; and remained home to Earth’s largest platform for citizen science—an online tool that connects researchers with millions of volunteers around the globe. During this time, annual attendance at the museum has increased by 35 percent.

Michelle earned her PhD in physics from Montana State University, and serves on several national and Chicago-area advisory boards. She lives just outside Chicago with her husband—who is also an astrophysicist—their daughter, and three cats.
