Student Profile:

Joseph Havens (BS `26):

Among the universities I considered, KU stood out not only for its thunderous cathedral of basketball but also for its inclusive and supportive academic environment. I will always think of KU Astrophysics for its welcoming attitude and its faculty’s dedication to student success.

MEET THE STUDENTS Student Profile:

Kate Boyer (BS `25):

During my Associate’s degree I was listening to a podcast and it mentioned ‘astrobiology.’ The study of life on other planets, and life’s origin on Earth, sounded very cool! It was right up my alley being both someone interested in the sciences and a lover of aliens and the like. Since KU has an astrobiology minor, this made the KU astronomy program a perfect choice.

Geology is another passion of mine. I love rocks, so the chance to do both astrobiology and geology related research was a

dream come true. My first research was cracking open rocks called gypsum and looking for microbes inside. Gypsum grows in water rich environments and nabs microbes as it grows. There is also a lot of gypsum on Mars so comparing what we find in those rocks to stuff on Mars can be very conducive to research.

Recently I’ve begun work in our university’s exoplanet lab; it’s been fun trying to learn everything.

After graduating in Dec. 2025 I want to go to graduate school in astrobiology. After graduate school, I would like to apply for an astrobiology research position preferably at NASA.

run, and analyze simulations of radio transmissions through ice.

After graduating from KU I plan to attend graduate school to work in either astrophysics (focusing on black holes) or cosmology (focusing on the Big Bang).

I have worked with Dr. Prohira on high-energy neutrino detection, where I utilize Python to build,

I expect to graduate in May 2026 with Bachelor of Science in both Astronomy and Physics, and a minor in German because I am interested in the German language and culture. Beyond academics, I am an avid volleyball player and enjoy watching soccer and KU sports. I am passionate about promoting LGBTQ+ inclusion in STEM and supporting outreach initiatives to encourage LGBTQ+ scientists. I believe in the power of education and enjoy helping others learn, fostering a collaborative and inclusive learning environment.

I’m also very involved in extracurricular activities! I spend my free time volunteering at a food pantry and observatory, TAing,

disability activism, Model United Nations, magazine editor for the department’s student magazine, and more.

I have had the privilege of attending astronomy seminars that cover the latest research topics, from exoplanets to cosmology. The eagerness of faculty members to involve undergraduates in their research teams, even when we are just starting out, has been incredibly motivating.

MEET THE FACULTY

1

KU currently has ten faculty members working, teaching, and researching in astronomy, space physics, and related fields: 1) Allison Kirkpatrick (Associate Chair): supermassive black holes and their host galaxies.

2) Betsy Mills: radio galaxy centers, starbursts, and active supermassive black holes.

3) David Besson: radio detection of ultra-high energy cosmic rays.

4) Greg Rudnick: how galaxies grow and evolve over cosmic time.

5) Hume Feldman: machine learning, cosmology, and the large scale structure of the universe.

Faculty Profile:

Steven Prohira Joining the faculty in Fall 2022, Professor Steven Prohira (PhD `18) is the latest astro-related hire. His astroparticle research advances the study of cosmic rays and

Alumni Profiles KU Astro & Space alums find their way to all corners of the Earth – and occasionally even beyond! Some stay in academia, while many others venture out into the real world.

To keep in touch with us, you can: • Send us all your latest successes and adventures at work or at home. (send to ianc@ku.edu).

• Share with us your latest email and mailing address.

• Join our LinkedIn group “University of Kansas Astronomy Students, Alumni, and Friends.”

And finally, remind your fellow alums to check in with us, too!

Issue 1, Dec 2024 Jim Hesser (BS `63): “Following retirement as DAO Director (2014) I reviewed NSF major facilities operating grants until COVID. I served on the boards of the Victoria Symphony and Victoria Summer Music Festival, and as scientific advisor to the Victoria production of Silent Sky – I used some of my CTIO photographic plates to show the actors what Leavitt and her Harvard colleagues worked with a century earlier. These efforts are founded upon the exposure to the liberal arts while pursuing my KU degree a very long time ago.

My wife Betty and I met in KU astronomy classes in Jan. 1963, married that August, and celebrated our 60th anniversary last year.”

Mark Stull (MA `67): “Practicing law and working on research to determine the feasibility of a novel type of subcritical fission reactor.”

Brent Hartley (BS `10): Program Director, University of California, Irvine, Paul Merage School of Business.

Michael Luhman (BS `88): Leads the Missile Defense Portfolio Institute for Defense Analyses (IDA, in Virginia). “My group assesses the test adequacy and performance of U.S. missile defense systems. I just hit 26 years at IDA and have worked on missile defense throughout. I visited KU last winter break and walked the halls just for fun. I was surprised at how much had changed since the 1980s.

Visiting Malott Hall again brought back some really pleasant memories.”

Lindsay Mayer Clark (BS `05): Chair of the Physical Sciences Department at Tarrant County College -South Campus (Texas).

“I am teaching Earth Science and Natural Hazards, and I am itching to get back to Astronomy.”

Richard Henry (BA `77): “I retired from the Physics and Astronomy Dept. at U. of Oklahoma in 2016. I continued research until 2022, when I completed a review paper on planetary nebulae with Karen Kwitter. My main effort since has been the study of jazz piano.”

Jenn Cooper (PhD `21): Staff Scientist at Arete Associates (California). “I split my time between project management for programs such as laser production / delivery, and machine learning / image analysis / spectral analysis.

One project involved trying to determine if any harmful agents or chemical weapons were sprayed in an area.

We did the algorithm development for an instrument that is put on front of a driving vehicle and scans the ground in the 7 13 μm range and goes through a set of chemicals in a spectral library that we developed in-house. We have a 90% correct detection rate, so it was a success.”

Ethen Schmidt (BS `21): Software engineer at Lockheed Martin (Colorado).

“It's been great being such a short distance away from all the great hiking and camping. I climbed a couple 13ers this summer which was quite the adventure.

Work has been going well too. I get to use a little bit of what I learned from all my Math, Physics, and Astronomy classes every day which is great. The undergraduate research work I did couldn't have been more valuable in my current career.”

Wichahpi King (BS `21) Astronomy grad school (UTAustin). “I work with AGN data from the HETDEX survey; I calculate Black Hole masses using the broad MgII 2800 Å emission lines. I also helped with a study on how poverty & income level affects our field (I sat on a AAS panel for this project) and I'm an executive committee and conference planning committee member for the Society of Indigenous Physicists (SIP) and helped plan our conference earlier this year.”
