JILA postdoctoral researcher Dr. Megan Bentley, a member of Heather Lewandowski’s research group, has been named a 2026 Arnold O. Beckman Postdoctoral Fellow. The prestigious national award recognizes Bentley’s innovative research and supports outstanding early‑career scientists in the chemical sciences as they transition toward independent research careers.

JILA Fellow and University of Colorado Boulder Physics Professor Heather Lewandowski and members of her lab have shattered a 25-year-old theory about how benzene forms in the interstellar medium, revealing that the long-accepted chemical recipe doesn’t work under space-like conditions. Their groundbreaking laser-cooling experiments open a new chapter in understanding the origins of complex carbon molecules in the cosmos.

In recent years, quantum technology companies have begun to pop up across the United States. These companies design technologies that tap into some of the unique properties of very small things like atoms and electrons. Such technologies include “quantum computers” that could one day discover previously unknown medications, or sensors that can detect signs of illness in a single puff of breath. But the growth of the industry also raises a major question, said physicist Heather Lewandowski, one of the project leads: How can the nation better prepare students to enter this uncharted industry?

Dr. Olivia Krohn, a former JILA graduate student and now a postdoctoral researcher at Sandia National Laboratories, has been awarded the prestigious Justin Jankunas dissertation award, given out by the American Physical Society (APS) division of chemical physics at the APS Global Summit conference. This award recognizes exceptional doctoral research that advances the frontiers of physics. Krohn’s award highlights her dissertation research, which bridges the legacy of JILA’s origins in astrophysics with its current role as a global leader in atomic, molecular, and optical (AMO) physics.

Physics lab courses are vital to science education, providing hands-on experience and technical skills that lectures can’t offer. Yet, it’s challenging for those in Physics Education Research (PER) to compare course to course, especially since these courses vary wildly worldwide.

To better understand these differences, JILA Fellow and University of Colorado Boulder physics professor Heather Lewandowski and a group of international collaborators are working towards creating a global taxonomy, a classification system that could create a more equitable way to compare these courses. Their findings were recently published in Physical Review Physics Education Research.

To highlight the pivotal role of federal funding in advancing quantum research, the National Science Foundation (NSF) hosted its inaugural Quantum Showcase on Capitol Hill two weeks ago. The event highlighted the potential of government-funded quantum initiatives and included NSF-funded quantum researchers nationwide. JILA, a joint institute between the University of Colorado Boulder and NIST, was represented at the event by JILA Fellow and University of Colorado Boulder Physics Professor Heather Lewandowski and JILA graduate student Qizhong Liang, a member of JILA and NIST Fellow Jun Ye’s research group.

While it may not look like it, the interstellar space between stars is far from empty. Atoms, ions, molecules, and more reside in this ethereal environment known as the Interstellar Medium (ISM). The ISM has fascinated scientists for decades, as at least 200 unique molecules form in its cold, low-pressure environment. It’s a subject that ties together the fields of chemistry, physics, and astronomy, as scientists from each field work to determine what types of chemical reactions happen there.

Now, in the recently published cover article of the Journal of Physical Chemistry A, JILA Fellow and University of Colorado Boulder Physics Professor Heather Lewandowski and former JILA graduate student Olivia Krohn highlight their work to mimic ISM conditions by using Coulomb crystals, a cold pseudo-crystalline structure, to watch ions and neutral molecules interact with each other.

Colorado 9News recently interviewed JILA Fellow and University of Colorado Boulder physics professor Heather Lewandowski as she discussed a recent paper with over 1,000 authors. This recent paper, published in the Astrophysical Journal, focused on solving the mystery of the Sun's corona, a ring of significantly hotter temperatures surrounding the Sun compared to its core. Lewandowski recruited over 1,000 undergraduate students as researchers to study this phenomenon as they analyzed data from observations of the corona. The entire project took multiple years and culminated in over 56,000 hours of research. In the 9News interview, Lewandowski stated: "It's really important for us to understand our Sun because it has a large impact on Earth."

JILA Fellow and University of Colorado physics professor Heather Lewandowski helped lead a group of more than 1,000 undergraduate students in a study looking at the temperatures of the Sun's corona. The corona, the outer layer, gets incredibly hot, and the study hoped to figure out why. Their research was featured in Popular Science Magazine, revealing the creativity and ingenuity of undergraduate students in scientific research.

For a new study, a team of physicists recruited roughly 1,000 undergraduate students at CU Boulder to help answer one of the most enduring questions about the sun: How does the star’s outermost atmosphere, or “corona,” get so hot?

The research represents a nearly-unprecedented feat of data analysis: From 2020 to 2022, the small army of mostly first- and second-year students examined the physics of more than 600 real solar flares—gigantic eruptions of energy from the sun’s roiling corona.

The researchers, partially lead by JILA fellow Heather Lewandowski, and including 995 undergraduate and graduate students, published their finding May 9 in The Astrophysical Journal. The results suggest that solar flares may not be responsible for superheating the sun’s corona, as a popular theory in astrophysics suggests.
