After 44 years and more than 10,000 students, College of Business Professor Emeritus Gary Campbell is officially trading global markets for nature walks. For four decades, he has helped the world understand the macro — the massive global markets of minerals and metals. In retirement, he’s turning his attention to the micro — the intricate veins of a dragonfly wing and the silent bloom of a Keweenaw wildflower.

Campbell arrived at Tech at a time when the College of Business was increasing cross-collaboration with the technological side of campus, including geology, mining and engineering. Campbell was a bridge. He founded the Master of Science in Mineral Economics program, now Applied Natural Resource Economics.

Learn more about Campbell’s legacy, hear his message to colleagues and find details about an upcoming celebration for all three of COB’s latest emeriti faculty on the College of Business Newsblog.

College of Sciences and Arts Dean LaReesa Wolfenbarger has selected Jeffrey Pettibone, visiting assistant professor in the Department of Psychology and Human Factors, for this week’s Deans’ Teaching Showcase.

Pettibone will be recognized at an end-of-term event with other spring showcase members and is a candidate for the CTL Instructional Award Series.

Pettibone has been a visiting assistant professor in the Department of Psychology and Human Factors for two years. He demonstrates a deep commitment to pedagogical excellence and student engagement. Since arriving, he has received student evaluations in the top 10% each of his four semesters and for a total of 10 of the 11 courses he has taught.

Especially noteworthy is the fact that Pettibone teaches foundational courses like Introduction of Psychology (PSY2000) and Developmental Psychology (PSY2300) with enrollments ranging from 50-100 students. Pettibone also leads the department’s two-semester research methods series where students learn the basics of research in the fall and develop a research project in the spring that they present in a poster session at the end of the semester.

“Pettibone effectively mentors a variety of student-led research projects, spurring curiosity and creativity, helping students to imagine possibilities and then seeing them to fruition,” says Richelle Winkler, chair of the Department of Psychology and Human Factors.

Pettibone creates an active learning environment in large courses and balances rigorous academic standards with genuine efforts to help students succeed. One student in his 60-student PSY2300 section highlighted his clarity and support: “The course objectives were always clear, and I felt like he truly cared about our success. He makes complex psychological concepts easy to grasp without watering down the science.”

Another student summarized Pettibone’s effectiveness in large classes: “Professor Pettibone has a way of making a large lecture hall feel like a small seminar. He is incredibly organized, and his passion for the material is contagious.”

Students attribute Pettibone’s high-quality visual aids as a reason why the larger enrollment classes remain easy to follow and academically engaging. Additionally, he uses a range of in-class activities to promote reflection and deepen learning. He incorporates “minute essays” and other short writing assignments that students find both enjoyable and effective for retaining complex content.

He also works with students to identify knowledge gaps before major assessments by offering pre-exam quizzes and incorporating gamified learning through “Jeopardy” review sessions. Students repeatedly identified the “Jeopardy” sessions as something they hope will remain part of future courses. In fact, the most common advice from students was simply to keep the class as it is. As one student put it, “Never change.”

Pettibone’s impact extends beyond the classroom. Winkler noted that he builds strong relationships with students and creates an atmosphere in which students feel comfortable seeking help outside of class. “Students are regularly waiting in our co-working space for a chance to meet with him after class to talk through their interests and ideas for digging deeper into material presented in class,” she said. 

“Dr. Pettibone has a rare ability to turn large, foundational lectures into intimate learning communities where every student feels seen and challenged. He sets the gold standard for maintaining high academic rigor while fostering a supportive and inclusive environment,” said Wolfenbarger.

Andrew Fiss (HU) and Laura Kasson Fiss (HU/PHC) are the authors of a short article published by MAA Convergence, a journal of the Mathematical Association of America.

The article is titled “Historically Speaking — A New Ballad of Sir Patrick Spens”.

In the article, Andrew Fiss and Laura Kasson Fiss combine their expertise in the history of math and British humor to analyze the poetical recasting of the first proposition of Euclid’s “Elements” from Arthur Quiller Couch (called "Q"). As they trace, Q initially published the poem in the Pall Mall Gazette, and it reached American mathematicians through the later Q Anthology and then republication in the journal of the National Council of Teachers of Mathematics (NCTM). As the authors argue, “A New Ballad of Sir Patrick Spens” combines jokes about Scots dialect as well as geometry, expecting readers to be familiar with traditions of border ballads and Euclidean propositions, and to be amused by their combination.

As the Van Pelt and Opie Library does not subscribe to MAA Convergence, the authors are sharing their eprint link for the first 50 copies of the article.

Melissa Baird (SS) attended the Innovative Models for STEM Workforce Development in Critical Technologies symposium held at the National Academy of Sciences on March 17. The one-day event convened experts across industry, academia and government to discuss preparing the future workforce and STEM education.

My UP Now reported that Michigan Tech Ph.D. students Kamand Sedaghatnia (chemistry) and Zixin Shi (computational science and engineering) earned Blue Cross Blue Shield of Michigan Foundation grants to support their health research projects.

The Daily Mining Gazette quoted Susan Liebau (chemistry) and Michigan Tech students Colin Nowicki (civil engineering), Isaac Zull (marketing) and Ron Kuitula (mechanical engineering) in a story about Tau Kappa Epsilon’s bathtub-pushing fundraiser benefiting St. Jude Children’s Research Hospital.

The Daily Mining Gazette mentioned Michigan Tech in a story about York Space Systems acquiring Orbion Space Technology, a MTU spinout specializing in satellite propulsion systems.

NHL.com, the Daily Mining Gazette, Sporting News, Yahoo! Sports, CBS Sports and 65 national news outlets covered Michigan Tech hockey defenseman Jack Anderson’s signing of a two-year, entry-level contract with the Dallas Stars.

MSE Seminar with Michael Knight

The Department of Materials Science and Engineering (MSE) is hosting a seminar presented by Michael Knight, a ceramic materials scientist currently working in the research and development organization at CoorsTek.

The seminar will be held today, March 20, at 4 p.m. in M&M 610.

Knight will present “Resilience, Reinvention, and Materials Science: A Professional Journey”.

From the abstract:
This seminar explores a nontraditional pathway into materials science and how fundamental research translates into applied industrial innovation. The first half of the talk provides a brief narrative overview of a nonlinear academic and professional journey, highlighting how reinvention, mentorship, and hands‑on research opportunities shaped the pursuit of materials science.

The second half focuses on research examining the valence state and microstructural distribution of dilute transition metal cation dopants in functional oxide ceramics. Leveraging magnetometry to gain new information about these dopants will be discussed, emphasizing the relevance to functional behavior in complex oxides. The seminar concludes by connecting this academic foundation to current research and development efforts within the R&D organization at CoorsTek, illustrating how fundamental materials characterization informs method development, innovation, and decision‑making in an industrial setting.

Knight’s path into materials science followed a nontraditional trajectory, beginning with military service before returning to education through community college while working full-time in a technical role. He later transferred to the University of California Santa Barbara to study physics, where undergraduate research in materials science motivated him to pursue a Ph.D. in Materials Science. His doctoral work focused on understanding valence states and microstructural distribution of dilute transition metal cations in ion-conducting solid electrolytes. Knight now leads and supports advanced materials analysis efforts in industry, bridging fundamental materials science with applied research and development.

Implantable Living Pharmacies: Engineering Durable Treatments for Chronic Diseases

Friday, March 20, 3–4 p.m. | Chemical Sciences and Engineering Building, 102

Biomedical Engineering Research Seminar Suman Bose, Ph.D. Mayo Clinic Arizona Abstract Implants carrying engineered cells offer transformative potential for treating chronic diseases, including autoimmune disorders, endocrine imbalances, neurodegenerative conditions, and cancer. These living pharmacies can deliver biologics directly to target tissues, eliminating the need for repeated injections and patient compliance challenges. However, clinical translation has been hindered by persistent challenges: foreign body responses and cellular dysfunction that compromise long-term therapeutic function. This talk will discuss three convergent strategies our lab has developed to overcome these fundamental barriers. First, we will present our biocompatible macrodevice platform, which enables sustained protein delivery in rodent and non-human primate models over extended periods. Second, we will describe advances in device design that allow devices to be folded into an injectable form factor, enabling minimally invasive implantation. Finally, we will present our latest findings on controlling foreign body responses through precisely designed chemical and biophysical surface modifications…
