Twice a Buff: Kerrie Ellzey’s path to physics

Twice a Buff: Kerrie Ellzey’s path to physics Kirsten Apodaca Thu, 09/04/2025 - 09:44

Kirsten Apodaca

Returning to college for a second degree takes grit and determination – and Kerrie Ellzey (Psyc’12, Phys’17) had both.

After completing her degree in psychology from �鶹��Ѱ��Boulder, Ellzey taught preschool for several years before deciding to make a change. In high school, she loved physics and missed the sciences.

“I specifically wanted to study physics because I wasn’t sure what I wanted to do as a career, but I wanted to understand how the world worked at a very basic level,” she said.

That curiosity shaped not only her academic focus but also how she engaged with the �鶹��Ѱ��Boulder community the second time around.

Reimagining the college experience

During her first bachelor’s degree, Ellzey wasn’t involved in many extracurriculars. Returning for a second degree allowed her to approach school differently. While an undergraduate in physics, she conducted undergraduate research and worked to improve community in the department.

“I completed an undergraduate honors thesis, got involved in CU-Prime, helped plan the Conference for Undergraduate Women in Physics, and volunteered on other community building efforts in the department,” said Ellzey.

Ellzey’s undergraduate research with Professor Alysia Marino focused on neutrinos – the most abundant and smallest particles with measurable mass in the universe.

As part of her research, Ellzey evaluated detector options used to monitor muons, a byproduct of creating the neutrino beam sent from Fermilab, a national laboratory that specializes in high-energy particle physics.

“We put commercial and prototype detectors into the beamline at Fermilab and compared their performance to simulated performance predictions. I did both the simulation analysis and the hardware data analysis.”

After defending her honors thesis and graduating with her second bachelor’s degree in physics, Ellzey looked to what was next for her career.

From academia to aerospace

She briefly worked at the Institute of Arctic and Alpine Research (INSTAAR) conducting arctic ice research before joining Ball Aerospace (now BAE Systems, Inc) as a material science engineer.

“Material science and detailed engineering was a fantastic way to become familiar with the company and technology, but after about a year I was feeling a desire to understand the larger context of what I was working on,” she said.

She then transferred into a tactical modeling and simulation group.

“I have had the incredible opportunity to create performance prediction models of RF Mission Systems and then attend flight and field test events that proved out the performance of these systems.”

She’s now expanding her work experience into a broader systems engineering role, but still with an emphasis on modeling and simulation as well as occasional test events. Ellzey also mentors earlier career engineers in performance prediction modeling and test data analysis, which she finds incredibly rewarding.

Her day-to-day in her current role varies depending on the project she’s working on.

“Sometimes I’m at a computer debugging code and crunching data, and sometimes I’m in a lab troubleshooting test hardware,” she said. “Every day I collaborate with folks from different disciplines, and periodically I make presentations and brief customers on the big picture impacts of our systems and their performance.”

Lessons from a non-traditional path

In a competitive job market, it’s not always enough to have the technical know-how.

“Show you are a well-rounded human and get technical work experience,” Ellzey advised.

As someone who now interviews others, she assumes candidates will have a research experience or internship. But those that also do something else with their time – like volunteering, leading a student organization, working as a learning assistant – are the ones that stand out.

Physics taught me how to persevere, self-teach, and gave me the technical foundation for a career in systems engineering.
- Kerrie Ellzey

“Those experiences help show that you will thrive in a team environment,” Ellzey added. “I didn’t put my preschool teacher work experience on my resume, but hiring managers asked about the gap in time. When I told them, that ended up being a huge selling point!”

Ellzey said she has frequently dealt with impostor syndrome because of her non-traditional career path and background. But after considering her collective experience, her mindset shifted.

“I realized all the seemingly random things I have done actually make me an asset to my team. Physics taught me how to persevere, self-teach, and gave me the technical foundation for a career in systems engineering. I also have the people skills to work well with folks of any background and that came from so many of the experiences and learning opportunities I had outside of the classroom,” said Ellzey.

Advice for future students

To make the most of your college experience, Ellzey recommends doing more than just going to class.

“College and early career can be difficult and isolating but having a community can help you be resilient during the challenges,” she said. “You will meet more people, be part of a larger community, and grow as a person.”

Ellzey’s journey is a testament to the power of curiosity and persistence. From her first degree at �鶹��Ѱ��Boulder, to teaching preschool, pursuing physics, and now launching her career in aerospace – her path has led her to success. For students considering a second degree or a career change, her advice is simple: pursue your curiosity and embrace your unique experiences. They just might be your greatest strengths.

Postdoctoral Associate JaeBeom Park was recently awarded the Sambamurti Memorial Lectureship from Brookhaven National Laboratory (BNL) for his work on the sPHENIX experiment. Park delivered the lecture, “The Final Mission of RHIC: Unveiling the Last Chapter of the Quark-Gluon Plasma with sPHENIX” to a packed audience at the BNL Physics Department on July 31, 2025.

The lectureship was established “in memory of Aditya Sambamurti, a young high energy experimentalist working on rare kaon decays at the BNL AGS, who died in 1992,” according to the BNL website. The lectureship is awarded yearly for “outstanding achievement” to high energy or heavy ion experimentalist researchers within 20 years of their PhD, and includes a $1,000 honorarium.

“I am honored to receive the Sambamurti Award and to have the opportunity to share my work with a broad audience, including many enthusiastic young students who are curious about science,” said Park.

After receiving his PhD from Korea University, Park joined the experimental nuclear physics group at �鶹��Ѱ��Boulder in 2023, working closely with Professors Dennis Perepelitsa and Jamie Nagle on sPHENIX.

sPHENIX is a large detector housed at Brookhaven National Laboratory, designed to learn more about quark-gluon plasma — a state of matter that existed for a brief moment after the Big Bang. The detector collects data on millions of particle collisions per second from the Relativistic Heavy Ion Collider (RHIC).

Hundreds of scientists and engineers have collaborated on building and operating the experiment. The detector is about two-stories high, weighs 1,000 tons, and requires round-the-clock support in the control room during data-taking periods.

�鶹��Ѱ��Boulder’s experimental nuclear physics group is deeply involved in sPHENIX, with Nagle serving as Run Coordinator during the 2024 collision data-taking, and Perepelitsa serving as Deputy Spokesperson. And since 2023, Park has spent extensive time in person at the experimental site.

“JaeBeom was a regular fixture in the sPHENIX control room, and a particular expert on the trigger and readout electronics, the data acquisition system, and on critical checks of the data integrity. He was even the designated “on-call” expert for large periods of time,” said Perepelitsa.

sPHENIX recently released its first physics results after three years of data-taking, setting the foundation to further explore the structure of quark-gluon plasma. The results lay the groundwork for future studies as scientists look to uncover properties of the early universe.

“JaeBeom has been instrumental in making three-years of data-taking at sPHENIX a success,” said Perepelitsa. “He has been making crucial contributions at a fundamental, technical level and really “living and breathing” the experiment.”

Park added “working on sPHENIX has been one of the most unique, challenging, and energetic experiences in my career. The Collaboration is full of passionate and dedicated people, and I’m constantly learning from them every day, especially from my group members from �鶹��Ѱ��Boulder.”

Welcoming new assistant professor of physics, Ivy Tan Kirsten Apodaca Tue, 08/12/2025 - 15:12

Kirsten Apodaca

The Department of Physics at the �鶹��Ѱ�� is thrilled to welcome Ivy Tan as a new Assistant Professor of Physics this fall.

Her interest in the field started with a love for physics and mathematics in high school. “I enjoyed understanding phenomena at a fundamental level,” said Tan.

She went on to major in physics and mathematics at the University of Toronto, where she was introduced to atmospheric and climate physics. She said, “it was a natural fit for me as it allowed me to apply my background in physics to my growing interest in climate change.”

Tan completed her doctoral studies in Earth and Planetary Sciences at Yale University in 2016. After her graduate studies, she was awarded several prestigious research awards at NASA's Goddard Space Flight Center.

A geophysicist with interests in climate and atmospheric physics, Tan’s research is centered on Earth’s clouds, radiation and climate. She studies the formation and dissipation of small-scale processes associated with clouds, their interactions with radiation and how they in turn influence the large-scale climate system.

For Tan, Boulder presents a vast opportunity for collaboration with other academic departments, institutes, and national laboratories in the area. She added, “from modelling at all scales to satellite remote sensing, there is so much potential for collaboration right here in Boulder with colleagues in atmospheric and oceanic sciences, applied mathematics, LASP and CIRES at �鶹��Ѱ��Boulder, in addition to NCAR and NOAA.”

She’s also looking forward to inspiring more students to pursue climate physics through teaching and research. “�鶹��Ѱ��Boulder and its surrounding institutions are a powerhouse in physics and climate science, and I can’t wait to collaborate with its leading researchers,” said Tan.

In Memoriam: P. Dale Kunz, professor emeritus of physics Kirsten Apodaca Tue, 08/12/2025 - 08:52

Peter Dale Kunz, professor emeritus of physics at the �鶹��Ѱ�� passed away in January 2025 at the age of 96.

Kunz earned his Ph.D. at the University of Washington in 1959 and came to Boulder as an acting assistant professor in 1962. He spent his career at �鶹��Ѱ��Boulder, rising through the ranks and retiring as a full professor in 1992.

Kunz was a member of the nuclear physics group, the largest research group in the department during his time here. The group operated a cyclotron on east campus at what was known as the Nuclear Physics Laboratory. The cyclotron was the first built between St. Louis and the West Coast and the experiment enabled more than 25 years of pioneering nuclear physics research.

As a theorist, Kunz worked closely with other members of the group. One of his most significant research contributions was a software package used to analyze experiments about low energy nuclear physics, dubbed “DWUCK” (Distorted wave – University of Colorado – Kunz).

After he retired, Kunz lived in the Pacific Northwest until a few years ago, when he returned to Boulder to be with family. Kunz is remembered as an exemplary colleague by faculty who worked with him.

A milestone year for the Boulder School for Condensed Matter and Materials Physics Kirsten Apodaca Thu, 07/31/2025 - 08:30

Kirsten Apodaca

This year marked the 25th year of the Boulder School for Condensed Matter and Materials Physics (BSS) which brings advanced graduate students, postdoctoral fellows and lecturers from around the world to �鶹��Ѱ��Boulder for the month of July.

The Boulder School for Condensed Matter and Materials Physics was established in 2000 to provide education for advanced graduate students and postdocs working in condensed matter physics, materials science and related fields. Students working at the frontiers of science and technology receive expert training not easily available within the traditional system of graduate education and postdoctoral apprenticeship.

BSS is directed by Leo Radzihovsky, Professor of Distinction in Physics at �鶹��Ѱ��Boulder. He is one of the school’s original co-founders, along with Steve Girvin (Yale), Matthew Fisher (UCSB) and Cristina Marchetti (UCSB). Each year, Radzihovsky and colleagues, along with an Advisory Board of distinguished scientists select a topical area for the July school.

This year’s BSS was titled “Dynamics of Strongly Correlated Electrons,” with scientific organizers Debanjan Chowdhury (Cornell), Sean Hartnoll (Cambridge), Minhyea Lee (�鶹��Ѱ��Boulder), Andrew Lucas (�鶹��Ѱ��Boulder) and Leo Radzihovsky (�鶹��Ѱ��Boulder). Participants (65 graduate and postdoctoral students) and international lecturers explored the profound and long-standing challenges in the field of correlated quantum materials through theoretical, experimental and computational frameworks.

Public lecture presented by Prof. Margaret Murnane.

Margaret Murnane, Distinguished Professor, gave the school’s annual public lecture, “Building the Quantum Microscopes of the Future: From Star Wars to Quantum Sculpting.” Her lecture focused on how advances in quantum physics have led to the development of next-generation microscopes and what this means for the future of imaging, materials, and related areas.

“It has been 25 rewarding years of hosting the Boulder Summer School every July – meeting, interacting and getting to know some of the most brilliant young physicists from around the world, the future of our condensed matter physics community,” said Radzihovsky. “It’s also a pleasure to host and reconnect with many of my dear friends and colleagues lecturing at BSS and to discuss the diverse frontiers of condensed matter physics."

When not attending lectures or poster sessions, participants explored Boulder and the surrounding area, taking organized hikes, exploring Pearl Street, and joining other social activities.

The school is supported by the National Science Foundation, with additional funding provided by the �鶹��Ѱ��.

Next year’s Boulder School for Condensed Matter and Materials Physics will focus on “Geometry and Topology in Soft Matter Physics.” Applications for the 2026 school will open in mid-fall and interested students should apply by January 1, 2026.
