A CENTERING FORCE DEAR FRIENDS OF CHEMISTRY: It has been a while since we published our last issue of the Catalyst. Many things have changed since then–we have new colleagues, lost some of our friends, weathered the complexity of the pandemic, and continued to build the department. What has remained the same is the underlying passion, drive, and excellence that I observe day to day in our faculty, staff, graduate and undergraduate students, and postdoctoral researchers. I see this while advising and mentoring my own research team and working with my colleagues and our staff to address challenges. Perhaps the clearest view of our culture was on display in October as we recognized our four 2023 Distinguished Alumni Awardees

(who will be highlighted in detail in the next issue!). Their message to our current faculty and students was the same: you are providing and receiving an outstanding education that will allow you to lead the next generation of scientists, managers, and students. Their message was inspiring and a grand reminder of why we do what we do every day. In this issue we feature the culture of our department and bring you up to date on several highlights from the last two years. This includes some descriptions of our successful alumni, including the 2020 Distinguished Alumni–Rik Tykwinski, Carrie Wager, and Raymond Price. In addition, a previous Chemistry Distinguished Alumnus, Clifton Sanders, has been recognized in several Universitywide honors, including the 2023 U

Distinguished Alumni Award and the 2023 Hugo Rossi Lectureship. Finally, we do a deep dive into one of our more recent graduates, Rory “Ziggy” Uibel and his adventures in growing a highly successful local instrument company. The issue also highlights faculty and students who have received prominent recognition and have had exciting research accomplishments. While there are many to acknowledge, I would like to give a shout-out to Cindy Burrows (Pauling Medal), Valeria Molinero (Irving Langmuir Award and induction into the National Academy of Sciences), Michael Morse (Distinguished Professorship), and Luisa Whittaker -Brooks (U Presidential Scholar, ACS-WCC 2024 Rising Star Award, and MRS Outstanding Early Career Investigator Award). It is always


rewarding to see our colleagues honored for their excellence! On a sad note, we lost several of our former colleagues, including Laya Kesner, Frank Harris, and Wes Bentrude. I was personally close with Wes as he retired soon after I arrived but remained present for several years while I was building my program. He was such a kind and giving person with an easy smile and great sense of humor. I will also note that his research on

understanding the reactivity of unusual radicals has circled into the mainstream many years after his initial publications. The organic chemistry community is utilizing his insights as the use of radicals has had a renaissance in recent years. As a final note, this is my last year as department chair. This has been a demanding job, and I look forward to passing the reins to my successor. However, I can say

with all honesty that working with such an incredible group of people has been a pleasure. The culture of our department–collaboration, excellence in education and science, and a good sense of humor–has been a centering force through the challenges encountered. Sincerely,

Chair Matt Sigman

And I really think that people should be making mistakes.” Above all, Ballance feels the most support and love from her mom and younger sister. “My mom raised me and my sister alone and taught us how to love the world around us even when things feel like they may be falling apart.” As for her sister, “she is the bravest, strongest

After deciding to take a summer chemistry course at a local college to fix a mistake in her schedule, she found herself surrounded by adults in a lab filled with chemicals she’d never worked with. “It was terrifying,” Ballance said, “especially the labs, because everyone knew what they were doing. I was scared of that class for so long, but I was determined to finish it. I ended up doing really well and learning more about myself and the course material than I had in any other class.” Her triumph in the class gave her the confidence she needed, and she’s been enamored with the world of chemistry ever since. Along with her undergraduate chemistry degree from Lewis & Clark College, Ballance also completed a minor in theater, discovering a refreshing “balance” between the two fields. “I feel like I can lose a lot of creative energy being in the science world, where you are dependent on repetition of trials and replicating

doing research, she hunted for more experience back home in Santa Barbara before applying to graduate school, and was accepted into the U later that year. Ballance makes the most of her time living in Utah, going backpacking, hiking, climbing, and skiing whenever she can. “I really love the outdoors,” she says. “If I had a dream job it would be working outside and doing chemistry.” Following graduate school, Aria Ballance plans to achieve her dream of living abroad while completing a postdoctoral fellowship. In the meantime, she’ll continue to explore her love of chemistry while she carefully plans her new chapter of adventures. “I haven’t figured out where I’m going to go yet, but my plan is to work hard, not give up, and to follow my bliss.” Right now, her bliss is decidedly a chemical one. <

While studying at the U, she researched total synthesis of natural products in Gary Keck’s lab and played on an intramural soccer team where she met her husband. Wager is a chemistry midfielder in her career, driven to cover a lot of ground by her passion for working in a fast-paced, team environment. After graduating from the U, she spent 17 years at Pfizer as Senior Principal Scientist, Director of Business Planning, Chief of Staff for Pfizer Medical, and Medical Strategy Lead in Oncology. Then she earned her MBA from MIT in 2017 before joining Ascidian Therapeutics. “I really found the place where my heart belongs, and that’s working in startups,” she says. “In those situations, it’s pretty high risk, but also high reward. The strength of the team is critical, and I really enjoy that part. I’ve always been into team sports. I

EXON-EDITING IS THE NAME OF THE GAME

The team Wager currently works with at Ascidian is taking a new approach to gene therapy, influenced by the organisms that the company is named after. Wager says, “We were inspired by what happens with sea squirts or ascidians because they re-engineer the transcriptome. They start as creatures that are free-floating … but then they become these structures after they re-engineer their transcriptome and are fixed on the bottom [of the ocean].” As sea squirts

mRNA to mature RNA is the excision or the cutting out of introns.” The splicesome is the enzyme responsible for removing the introns and leaving the exons which are then joined to form the mature strand of RNA. Ascidian designs molecules to target mutant exons and replace them with a wild-type version. “We use these molecules that are packaged in an adeno-associated virus to gain entry into the nucleus. Then those molecules are built to bind to specific locations in messenger RNA. … The

(Ascidiacea) mature, they self-edit their messenger RNA to change the proteins that are expressed and, ultimately, their structure. Ascidian’s strategy for fixing genetic diseases in humans is different from other existing methods of gene therapy because it works by editing RNA through a process that is already inherent to the cell. “DNA is transcribed into RNA in the nucleus,” Wager explains. “It’s initially transcribed into pre-messenger RNA (pre-mRNA) and pre-mRNA becomes
