Center for Healthy Aging Team

Leadership Team:

Nicole Ehrhart

Nicole Ehrhart, V.M.D
Director, Columbine Health Systems Center for Healthy Aging
Dr. Ehrhart is the Director of Colorado State University’s Columbine Health Systems Center for Healthy Aging and a Full Professor in Clinical Sciences at the College of Veterinary Medicine and Biomedical Sciences at Colorado State University. She holds the Ross M Wilkins MD Limb Preservation Foundation University Chair in Musculoskeletal Biology and Oncology. She is the Director of the Laboratory of Comparative Musculoskeletal Oncology and Traumatology and has been involved in limb preservation research, regenerative medicine, tissue engineering and cancer research for the last twenty years. She is actively engaged in translational aging research to improve health and lifespan for aging patients-both human and canine- and she focuses on comparative medicine as a powerful tool to bring new therapeutic strategies to slow aging.
She holds joint faculty positions in Colorado State University’s School of Biomedical Engineering, Cell and Molecular Biology program, and the University of Colorado Gates Regenerative Medicine Center and University of Colorado Cancer Center. In addition to her leadership roles in many prestigious national and international scientific organizations (ACVS, VSSO, VOS, WVOC), Dr Ehrhart was also the first woman to be granted a University-level Endowed University Chair at Colorado State University.

Deana Davalos, PhD
Associate Director, Columbine Health Systems Center for Healthy Aging
Deana Davalos, PhD is a licensed psychologist, Director of the Aging Clinic of the Rockies (ACoR), Associate Director of the Columbine Health Systems Center for Healthy Aging and a Professor in the Cognitive Neuroscience program in the Department of Psychology at CSU. She has published on issues surrounding cognitive aging and the neurophysiology of aging and is part of a multi-disciplinary research team focused on developing community-based interventions for individuals with dementia-related diseases and their caregivers.

Karyn Hamilton, RD, PhD
Associate Director, Columbine Health Systems Center for Healthy Aging
Karyn L. Hamilton, RD, PhD is a Professor and the Director of the Translational Research on Aging and Chronic Disease (TRACD) laboratory in the Department of Health and Exercise Science at Colorado State University in Fort Collins Colorado. She also has the privilege of serving as an Associate Director of the Columbine Health Systems Center for Healthy Aging at CSU. Karyn earned her PhD at the University of Florida and completed post-doctoral fellowships at Baylor College of Medicine and the University of Florida. The overall objective of the TRACD laboratory is to understand the role of adaptation to stresses and maintenance of a functional mitochondrial proteome in the context of extending healthspan and maintaining function with aging. To accomplish this objective, she uses models of long life and increased healthspan including exercise, nutritional, pharmacological, and genetic models. In the TRACD lab, they enjoy using a highly collaborative approach and employ in vitro systems, in vivo animal models, and human participants to help identify mechanisms of healthspan extension and to translate their findings.


Annette Foster, CPA
Director of Operations and Grant Management
Annette joined the Columbine Health Systems Center for Healthy Aging in late January 2020 as the Director of Operations and Grants Management. She plays a vital role in helping to facilitate grant submissions, post award support, overall operations of the Center’s facilities and is a providing invaluable leadership and vision during our growth phase. Annette is a graduate of Colorado State University’s College of Business, a CPA, a former financial auditor and sole proprietor, and prior to joining the Columbine Health Systems Center for Healthy Aging team, she served as a research project manager for CSU’s Atmospheric Science department. She brings her extensive experience from all these various roles to contribute to the success of the Center, and hopes to gain some valuable tips for her own healthy aging as well! Annette was raised in Iowa and moved to Colorado with her husband in 1988. She has a daughter who graduated from CSU and a son who graduated from CU Boulder last spring (yes, there is a bit of rivalry during the Showdown) and her husband earned his master’s degree at CSU. She loves to hike, ski, snowshoe, camp, backpack, and cycle so Colorado is the perfect home and clearly, CSU is a big part of her life.

Administrative Staff


Ali Murphy
Administrative Assistant, Columbine Health System’s Center for Healthy Aging and Kendall Reagan Nutrition Center
Allison Murphy, or Ali as she likes to be called, is excited to have joined the team at the CHS Center for Healthy Aging on Dec 2 as the new Administrative Assistant. She recently moved to Fort Collins from Northern Virginia where she worked for a law firm specializing in Special Needs Trusts, Estates, and Adult Guardianship. Outside of work, she loves hiking, biking, trying her hand at artistic endeavors, cooking, and playing games with friends. Ali is excited to facilitate faculty in all aspects of Center engagement and to be the friendly face you see at the reception desk when walking into the Center between 8 am and 5 pm. Please contact Ali for help with directing clinical trials participants, room reservations, website update requests, office needs, mailing, Center AV issues, scheduling and events planning.

Hannah Halusker

Hannah Halusker
Communications and Outreach Coordinator
As the Communications and Outreach Coordinator, Hannah develops multi-media communications and plans outreach events to help amplify the research and programming offered by the Center for Healthy Aging. She comes to the Center from South Carolina, where she received her B.S. in Genetics (2017) and M.A. in Communication, Technology and Society (2020) from Clemson University. At Clemson, Hannah served as a science writer in the College of Science and then as the director for a science and arts festival in nearby Greenville, S.C. She is thrilled to bring her passions for science communication and engagement to her role here at the Center. When she isn’t working, you can find Hannah running, biking, reading, doing yoga, or hiking one of the many trails near her new home in Fort Collins.

Center Faculty

Tom LaRocca, Ph.D.
Healthy Aging Project Co-Founder
Tom LaRocca is an assistant professor and director of the Healthspan Biology Lab in CSU’s department of Health and Exercise Science. His laboratory studies the molecular biology and physiology of aging, and he is particularly interested in translational research (using laboratory science to develop practical applications or treatments that can help people). Current projects are focused on finding biology-based ways to increase healthspan, the period of life during which we are healthy and productive. Tom is also a former high school chemistry teacher and college instructor, so he enjoys bringing his interests into the classroom.
