The Next 150 podcast is about what's ahead — but this episode starts by looking back.

As Colorado marks 150 years of statehood, the nation approaches its 250th birthday, and CSU's Archives and Special Collections celebrates 50 years of preserving the university's history, we sat down with two people who know how CSU's history fits into that shared story better than anyone — Mark Shelstad, Head of Digital and Archive Services, and Clarissa Trapp, Instruction and Outreach Archivist, at CSU Libraries.

They provide an inside look at a collection spanning 550 archival collections, 24,000 rare books and over 150 terabytes of digital files — from a piece of cuneiform dating back to 2350 BCE, to born-digital content captured today. They share how the archives narrowly escaped the 1997 Spring Creek flood, what makes documenting a land-grant university unique, why today's students are active creators of CSU's history, and what the future of preservation looks like in an increasingly digital world.

More about our guests:

Mark Shelstad is the Head of Digital and Archive Services at CSU Libraries and an associate professor. He holds a B.A. in History from the University of Minnesota-Morris and an M.A. in Public History with a specialization in archival administration from the University of Wisconsin-Milwaukee. Mark got his start through a graduate internship at the Minnesota Historical Society and went on to work at the University of Wyoming's American Heritage Center, the University of Texas at San Antonio Libraries as Head of Special Collections, and the Wyoming State Archives as Deputy State Archivist before joining CSU 11 years ago. He and his team manage CSU's institutional memory, collections relating to Colorado agriculture and water, special collections and born-digital content from across campus.

Clarissa Trapp is CSU Libraries' Instruction and Outreach Archivist and an assistant professor. She holds a B.A. from Northwestern College in Orange City, Iowa, and a M.L.I.S. from San Jose State University. Clarissa started her career at Living History Farms in Urbandale, Iowa, where she spent six years working at a living history museum before arriving at CSU as a graduate student in 2009 to study history. A summer job in the archives shifted her path — she joined the staff as a Digital Collections Technician in 2016, earned her library science degree during the pandemic and stepped into her current faculty role in 2024. She specializes in connecting campus and community members with archival materials and is a go-to expert on Colorado and CSU history.

Anderson Cooper with 60 Minutes visited CSU’s campus to learn more about the groundbreaking work led by Dr. Stephanie McGrath and Dr. Julie Moreno, researchers in CSU's College of Veterinary Medicine and Biomedical Sciences working alongside aging dogs and their owners to better understand how dementia develops. At CSU, those lived experiences are fueling a first-of-its-kind effort to understand brain aging in real-world conditions in both canines and humans.

Stephanie, a veterinary neurologist directing CSU’s Brain Research Center, and Julie, a neurotoxicologist and associate director, partner with the national Dog Aging Project to follow thousands of dogs—including President Amy Parsons’ pug, El Jefe—across their lifetimes. Their Brain Health Study is revealing striking similarities between canine cognitive decline and human Alzheimer’s disease.

In this episode, they share how owner generosity, national collaboration, and cross-campus mentorship are accelerating progress toward earlier detection, better support for families with aging pets, and ultimately more effective treatments for both canine and human dementia. They also share their behind-the-camera experience with 60 Minutes, and highlight the essential role of CSU students who help drive this research through sample processing, data analysis, and hands-on lab work.

Don't miss El Jefe's special appearance in this episode, reminding us that behind every data point is a beloved family member.

Six-time Olympic gold medalist Amy Van Dyken returned to Colorado State University to be inducted into CSU Athletics’ inaugural Ring of Honor, a recognition reserved for the most influential athletes in Ram history.

While back on campus, Amy joined President Amy Parsons for a wide-ranging and deeply personal conversation about the moments that shaped her journey, from nearly quitting swimming before transferring to CSU, to finding the right coach at the right time, breaking American records, and winning Olympic gold.

She reflects on the friendships and mentors who defined her CSU years, the lessons that carried her through elite competition, and how discovering renewed purpose beyond the pool has shaped the work she’s doing today. Fresh off a cover feature in People magazine and preparing to launch her own podcast, Amy speaks about using her platform for disability advocacy and visibility.

The result is a candid, funny, and profoundly human conversation about identity, resilience, and staying true to yourself. This episode is a reminder that greatness is rarely linear, and that resilience and authenticity matter more than medals alone.
