On August 27, 2024, scholars, trustees, and friends of UConn gathered at the University of Connecticut School of Law to honor members of the university community elected to the National Academies of Sciences, Engineering, and Medicine. Established by an Act of Congress in 1863, the National Academy of Sciences was followed by the National Academy of Engineering in 1964 and the National Academy of Medicine in 1970, all under the same congressional charter. Collectively, they are known as the National Academies.

“Few honors can compare with election to a National Academy. It is a recognition by peers and the Academy itself of outstanding achievements in research and scholarship,” President Radenka Maric said at the celebration. Six UConn faculty members are elected members of the National Academies, with the most recent being Professor of Physics Nora Berrah, whose election was announced in May 2024.

Department Head greeting

Dear Friends of UConn Physics,

Last year, I wrote to you as a new Interim Head of Physics and only barely a month into my appointment. During the past year, we conducted a search for a permanent head and I was selected. For this, I am very grateful for the trust and support I received from the department. The past year has been a bit of a rollercoaster: on the one hand, the complex budget situation has preoccupied the department heads and upper administration and student protests sparked discussions about free speech and activism on campus. On the other hand, the Physics Department had another excellent year in terms of research, teaching, and outreach and I had the pleasure of meeting several of our generous donors.

The most notable achievements of the past year were the election of Prof. Nora Berrah to the National Academy of Sciences, one of the highest honors in science, and her appointment as a UConn Board of Trustees Distinguished Professor, the highest honor at UConn. These will be celebrated at a special Edward Pollack Distinguished Lecture, on October 14, 2024, given by a longtime friend and colleague of Nora’s, Prof. Philip Bucksbaum, himself a member of the National Academy of Sciences and the Marguerite Blake Wilbur Professor in Natural Science at Stanford University.

A number of other faculty received notable awards this year. Prof. Moshe Gai will travel to Romania on a U.S. Fulbright Scholarship. Two faculty received awards from the College of Liberal Arts and Science (CLAS): Prof. Peter Schweitzer for Faculty Mentoring of Faculty and Prof. Erin Scanlon for promoting Climate, Diversity, Equity, and Inclusion. CLAS also funded a Diversity, Equity, and Inclusion Initiative: “UConn STARs (Science, Technology, and Astronomy Recruits),” Prof. Cara Battersby, PI.

We gave out our two undergraduate awards: the Katzenstein prize for the best undergraduate research paper went to Danya Alboslani and our Mark Miller award to fund a summer research project went to Leilani Ainsworth, working with Prof. Simone Colombo

We are fortunate to welcome two new faculty this year:

  • Assistant Professor Aleksandra Kuznetsova is currently a fellow at the Flatiron Institute and works on star and planet formation. She will join us this August.
  • Assistant Professor Shohini Bhattacharya currently holds an Oppenheimer Fellowship at Los Alamos National Laboratory in theoretical nuclear physics and will join us in January 2025.

This was also a great year for outreach. We welcomed over 100 enthusiastic second graders for a variety of hands-on activities, organized by Prof. Jason Hancock and Sarah Trallero. We held a viewing party for the opening of our newly renovated observatory, spearheaded by Prof. Matt Guthrie and we got permission to officially name it in honor of the late Prof. Cynthia Peterson, who funded and built the observatory in 1980. And, we had another exciting eclipse viewing party organized by Prof. Jonathan Trump – the second in seven years! We are looking forward to hosting CU*IP: Conference for Undergraduate Women and Under-represented Minorities in Physics, sponsored by the American Physical Society. It will take place in January2025 and is being organized by Prof. Nora Berrah, along with a large local organizing committee. Finally, I would like to cordially invite you to attend our 26th annual Katzenstein Distinguished Lecture on Friday, November 15, 2024, which will be held in our department. This year’s speaker is Professor Adam Riess from Johns Hopkins University where he is the Bloomberg Distinguished Professor. He was a joint winner, with Drs. Saul Perlmutter and Brian P. Schmidt, of the 2011 Nobel Prize for Physics, awarded “for the discovery of the accelerating expansion of the Universe.” I hope you can all attend and catch up on everything that is going on in the department and the Universe! I look forward to seeing you there.

Sincerely,

George Gibson
Department Head, Physics

UConn Physics Department Hosting January 2025 CU*iP.

Every year, the American Physical Society (APS) sponsors CU*IP – Conference for Undergraduate Women and Gender Minorities in Physics – at several locations around the country. This year, led by Prof. Nora Berrah, UConn Physics applied to host this national conference in Storrs and our proposal was accepted for January 24-26, 2025! The purpose of the conference is to bring together over 120 undergraduates from around the country to learn about many research areas in physics and also to lean many skills for pursuing a career in Physics or Science, such as networking, applying to graduate school, finding role models in academia or industry, learning how to succeed as an underrepresented minority, etc.

While the conference is partially funded by the APS, the host institution needs to raise a substantial amount of funds. So far, we have commitments from UConn, some generous donors, such as the Ed Eyler and Karen Greer foundation, alumnus Mark Miller, and the Del Boca family, as well as the American Association for the Advancement of Science, and Mirion Technologies.

The current members of the local organizing committee, composed of faculty, staff and students, are Cara Battersby, Tom Blum, Cameron Brady, Carrie Cichocki, Simone Colombo, Meg Davis, Elena Dormidontova, George Gibson, Matt Guthrie, Adam Kolano, Luchang Jin, Dani Lipman, Jessica Mitlehne, Michael Rozman, Dave Perry, Erin Scanlon, Peter Schweitzer, Juliette Stecenko, Sarah Trallero, Kaley Wilcox, Alan Wuosmaa and Nora Berrah.

The planned events demonstrate the Physics Department’s and UConn’s commitment to helping undergraduate women and gender minorities pursue physics following their undergraduate degree by providing them the opportunity to learn about different career tracks in STEM fields, graduate studies, and various professions in physics.

We will be very grateful to receive any donations to assist the Department in hosting the conference, which will be used to cover students’ meals, accommodation and travel, as well as the invited speakers’ and panelists’ travel and accommodation.

UConn STARs visits Hartford Public High School

The UConn STARs group visited Hartford Public High School (HPHS) to teach physics for a total of eight class periods from May 6th-9th, 2024. UConn brought 16 undergraduate students from the STARs program to HPHS for our annual outreach program, during which we interacted with about 100 high school students. We collaborated with physics teacher Dr. Thomas Longyear to develop four lesson plans on topics of: 1) Phases of Matter, 2) Waves, 3) Electrostatics, and 4) Gravity over the course of the academic year. During our visit to HPHS, the STARs participants led these engaging lesson plans with hands-on demos and activities, over the course of four days. The goal of the STARs program is to improve the retention of students from Historically Excluded Groups (HEGs) in physics at UConn by addressing key factors responsible for their attrition. We have academic year events that focus on social engagement, professional development, and community building. The STARs program just concluded its 3rd year, with consistent progress and growth, and is looking forward to continued growth in our fourth year!

Pictured below are the STARs participants and the HPHS students during our May 2024 visit.

Prof. Moshe Gai Awarded 2024-2025 Fulbright U.S. Scholar Award


Professor Moshe Gai, the director of the Laboratory for Nuclear Science, aka the Astrophysics Laboratory, https://astro.uconn.edu, was awarded a 2024-2025 Fulbright US Scholar Award to teach and do research in Romania. He will spend five months at the newly constructed world highest power laser lab (10 PW), the Extreme Light Infrastructure Nuclear Physics (ELI-NP), recently constructed by the EU in Bucharest, where Prof. Gai plans to apply expertise he gained working at Duke University for using Time Projection Chamber (TPC) detectors with gamma-beams to study stellar process in the lab.

Nobel Prize Winner, Professor Adam Riess, Katzenstein Distinguished Lecturer

The University of Connecticut, Department of Physics is proud to announce the 26th Annual Katzenstein Distinguished Lecturer that will be on Friday, November 15th. For the details of the lecture see the Web Calendar post.

Adam Riess is a Bloomberg Distinguished Professor, the Thomas J. Barber Professor in Space Studies at the Krieger School of Arts and Sciences at Johns Hopkins University, a distinguished astronomer at the Space Telescope Science Institute and a member of the National Academy of Sciences. He received his bachelor’s degree in physics from the Massachusetts Institute of Technology in 1992 and his PhD from Harvard University in 1996. His research involves measurements of the cosmological framework with supernovae (exploding stars) and Cepheids (pulsating stars). Currently, he leads the SHOES Team in efforts to improve the measurement of the Hubble Constant and the Higher-z Team to find and measure the most distant type Ia supernovae known to probe the origin of cosmic acceleration.

In 2011, he was named a co-winner of the Nobel Prize in Physics and was awarded the Albert Einstein Medal for his leadership in the High-z Supernova Search Team’s discovery that the expansion rate of the universe is accelerating, a phenomenon widely attributed to a mysterious, unexplained “dark energy” filling the universe. The discovery was named by Science magazine in 1998 as “the Breakthrough Discovery of the Year.” His accomplishments have been recognized with a number of other awards, including a MacArthur Fellowship in 2008, the Gruber Foundation Cosmology Prize in 2007 (shared), and the Shaw Prize in Astronomy in 2006.

A Team Effort is Giving New Life to a Classic Observatory

Elaina Hancock – UConn Communications

After nearly 20 years of being out of commission, UConn’s East Road Observatory is back up and running. The observatory will be renamed in a ceremony on October 21st where the team that restored the facility will demonstrate its capabilities. (Contributed photo)

Professor Cynthia Peterson was the first woman on the UConn physics faculty, and over the course of her 49 years at the University, she was known for her enthusiasm and passion for teaching and outreach and was always generous with sharing her knowledge. She was also known for her pursuit of the installation of an observatory j

Less than two weeks after touring the inside of the observatory in January of 2023, the team, including Allen Hall (pictured), began taking apart the old telescope and started working on restoring the facility.

ust off campus in Storrs, and in 1970 she and machinist Richard Mindek built the East Road Observatory.

Sadly, after a few decades of use, the observatory eventually fell out of repair and was largely forgotten until recently. A team, including employees, students, researchers, an alum, and an award-winning telescope builder, have breathed new life into this important piece of research equipment and UConn history.

In the fall of 2022, Physics Assistant Professor-in-Residence Matthew Guthrie learned about the observatory and started to wonder about its history.

“When I learned that it was no longer in use, I asked around to see why and how we could get it up and running again. Getting it fixed up was not in my skillset, so I didn’t think too much more about it,” says Guthrie. “Then Allen Hall, a local award-winning telescope designer, emailed our department chair out of the blue in January. He wanted to donate a telescope that he built. We connected and I told him about the derelict observatory, about a week later we were taking it apart.”

Guthrie reflects that the facility was in rough shape, and Hall later admitted he thought it was a lost cause, but they stuck with it. Now, after months of repairs, troubleshooting, and cleaning out critters and junk, the observatory is back in action and will be formally renamed at a ceremony scheduled for Tuesday, October 24th where Guthrie says they plan to demonstrate its upgraded capabilities.

Guthrie says jumping straight into the restoration has been an amazing and collaborative learning experience.

“I’m learning as much as I can from him (Hall), and his mechanical and technical skills are exactly what we needed to get this place restored to its former glory, and given the work and upgrades we’ve already made, they’re even better than the original design.”

All the while, Guthrie has tried to find out as much as he can about the observatory’s history. For instance, there is also an additional cement pad and utility hookups that were not previously used, and there are hopes that the facility can be expanded in the future to include a classroom, says Guthrie.

An alum who worked in the dome as a student and has also helped with the restoration effort, Dennis Perlot ’82 (ENG), saw the logbook and remembered the last, ominous entry dating from 2009 which read: “Dome stuck, mount frozen.” Perlot says the now-lost logbook also contained entries about asteroids, comets, and other discoveries.

Here Guthrie is working on reassembling the telescope. He says, “My graduate and postdoc work was mostly theory-based, so being back in a place where I can literally get my hands dirty again makes me happy, and seeing the results of our labor has been rewarding.” (Contributed photo)

Other challenges have grown up around the observatory, says Guthrie, because when it was built, the site was likely in the middle of an empty field. Decades later, the field now hosts a patch of trees and agricultural research fields.

Guthrie says the agricultural research farm staff, including Farm Manager Travis Clark, has been very supportive in helping to remove some of the trees when they can. Though people working on the farm have wondered what the strange building was for a while, now it presents an opportunity for new collaborations. Guthrie says one plan is to plant a “moon garden” around the building with night-blooming flowers.

“Getting the facility back up and running has been an amazing and rewarding experience. This will be a force for good in the department and at the university,” says Guthrie. “Our department has big-shot astrophysicists who work on JWST and Hubble. They like their telescopes to be in space, but having a telescope here is a powerful thing.”

UConn researchers have access to a network of telescopes around the world but time on the scopes requires fees after submitting proposals justifying the need for research time on the scopes. Now, Guthrie says students and researchers can get some hands-on experience with an earth-bound scope right here in Storrs.

“There’s nothing more fun than going through the theory in class and then seeing what it looks like with your own eyes and making that connection. That’s one of my basic philosophies of being a teacher, you can do all the theory that you want, and you probably can be pretty good at it. But if you can’t apply it, and see what that theory does in real applications, there’s no point. Things like this observatory are great tools for that building perspective.”

The team repaired, cleaned, and upgraded the observatory and it is better than before.

Upgrades to the facility include GPS for tracking the stars, enabling different kinds of research the observatory was not capable of previously, and Guthrie hopes to set up the system so it can be controlled remotely.

“With tracking, the scope rotates just a little bit at a constant rate to track along with the motion of the stars and that lets us do real science because you must look at something for a long time to really study it. One of the things that we’re excited to do is exoplanet studies where you need to take a few hours of exposure to accurately measure how much light you’re getting from the star so that any variability in that light you can attribute to a planet passing between us and the star. Doing that requires accurate tracking.”

At sunset on October 24th, following the short opening and renaming ceremony, Guthrie says they will fire up the new 16-inch telescope for an exploration of deep sky objects, planets, and (if visibility allows), the Apollo 15 landing site.

Nobel Prize Winner, Professor Gérard Mourou, Katzenstein Distinguished Lecturer

The University of Connecticut, Department of Physics, is proud to announce that on October 20, 2023, Gérard Mourou, professor and member of Haut Collège at the École Polytechnique and A. D. Moore Distinguished University Professor Emeritus at the University of Michigan and 2018 Nobel Prize winner, will be presenting the 25th Distinguished Katzenstein Lecture.

For the details of the lecture, see Physics Events Calendar

Gérard Mourou received his undergraduate education at the University of Grenoble (1967) and his Ph.D. from University Paris VI in 1973. He has made numerous contributions to the field of ultrafast lasers, high-speed electronics, and medicine. But, his most important invention, demonstrated with his student Donna Strickland while at the University of Rochester (N.Y.), is the laser amplification technique known as Chirped Pulse Amplification (CPA), universally used today. CPA revolutionized the field of optics, opening new branches like attosecond pulse generation, Nonlinear QED, and compact particle accelerators. It extended the field of optics to nuclear and particle physics. In 2005, Prof. Mourou proposed a new infrastructure, the Extreme Light Infrastructure (ELI), which is distributed over three pillars located in the Czech Republic, Romania, and Hungary. Prof. Mourou also pioneered the field of femtosecond ophthalmology that relies on a CPA femtosecond laser for precise myopia corrections and corneal transplants. Over a million such procedures are now performed annually. Prof. Mourou is a member of the U.S. National Academy of Engineering, and a foreign member of the Russian Science Academy, the Austrian Sciences Academy, and the Lombardy Academy for Sciences and Letters. He is Chevalier de la Légion d’honneur.

Physics Faculty Work to Improve Accessibility and Destigmatize Disability Across CLAS

About 20% of UConn students are supported by the Center for Students with Disabilities. The true percentage of students who need help is even higher. With so many students who require diverse ways of learning, how can faculty make sure their teaching is adequate, effective and inclusive for all students? In order to address this situation, CLAS has supported the Accessibility Fellowship Program during the 2022-2023 academic year with the goal to study disability and improve the accessibility situation at UConn and generally in higher education. Indeed, research shows that these students can perform at the highest standards in the classroom and in research, if they are given appropriate conditions to do so. One of the fellows in this program was our Dr. Erin Scanlon, Assistant Professor in-Residence at the Avery Point regional campus. The Center for Students with Disabilities makes a difference by addressing aspects related to, e.g., submitting assignments or taking tests. This is important but not enough. Instructors can make an even bigger difference at a much earlier stage, before submitting homework or taking tests, namely while the students learn in the classroom. Small changes in the classroom teaching can significantly improve the performance of the students. Which small changes can faculty implement? A lot is known about this thanks to the research of Dr. Scanlon and other scholars in Physics Education Research (PER) who study the learning needs of students with special needs.
