The 4D Team

The University of Denver 4D team, supported by a unique partnership of executive leadership in student affairs, academic affairs and career and professional development, develops and operationalizes strategic goals designed to enhance the 4D Experience at DU. They do so in three critical ways. First, by educating the DU community and offering consultations to raise awareness, increase dialogue and elevate practice around the 4D model of holistic student development. Second, by building creative capacity to support and generate innovative approaches to embedding and amplifying the 4D experience. And third, by engaging the community through strategic initiatives and programming, in close collaboration with campus partners, to ensure that the DU experience is the 4D Experience.  

If you have questions about the 4D Experience, or want to know how to get involved, the 4D team invites you to reach out.

Dr. Willer’s work is guided by two questions: 1) how do grievers narrate their lives against the backdrop of complex systems of power? and 2) how can we engage storytelling, art, and embodied practices to cultivate well-being, communication, creativity, compassion, and community in the face of illness, death, and loss? Erin teaches several courses at DU, including Communicating Grief and Loss; Communication, Compassion, and Craftivism; Visual Narratives of Women’s Health; and Running as Feminist Embodiment.

Dr. McRae is an affective scientist who studies emotion regulation - how we're able to control (and how we're not able to control) our emotions. To do this, she uses a variety of methods - questionnaires, laboratory tasks, peripheral physiology, and brain imaging - to examine what works and what doesn't to change emotion in the body and the brain. Dr. McRae has been deeply involved in Student Success efforts at DU since 2019 and is excited to integrate her scholarship around emotion and resilience with other aspects of well-being to support more dimensions of student success at DU.

Dr. Taczak is a teacher and scholar and the current co-editor of Composition Studies. Her award-winning research centers on composition theory, pedagogy, and curriculum, specifically focusing on reflection and teaching for transfer. The first-year writing curriculum, Teaching for Transfer (TFT), has been adapted at multiple institutions across the country and internationally. The book, which outlines the curriculum, Writing across Contexts: Transfer, Composition, and Sites of Writing received the 2015 Conference on College, Composition, Communication Research Impact Award, and the 2016 Council of Writing Program Administrators Best Book Award. This research has been supported by multiple national grants and several faculty research grants from DU. In response to this research, she has been asked to give keynote addresses and lead faculty workshops at institutions across the country and internationally. As the 4D Faculty Fellow of Reflection, she hopes to bring what she has learned from her research on transfer and reflection into helping elevate conversations and understandings about reflection at DU.

Cris Tietsort, Ph.D.

4D Faculty Fellow of Character; Assistant Professor, Communication Studies

The heart of Dr. Tietsort’s research centers on how we can strengthen human connection. For him, this has led to research on empathy and compassion in personal and organizational contexts. Much of his research has examined the contextual factors that limit or constrain compassion, such as how organizational discourses impact whether or not people receive compassion at work. He is also very interested in how it is that we can cultivate empathic and compassionate abilities as well, such as pedagogical theories that help people *become* more empathic as opposed to just understanding what empathy is. In his role as 4D Faculty Fellow of Character, he hopes to partner with other faculty to think critically about the ways we are equipping our students with enduring qualities and commitments - like empathy and compassion - that will support their ability to live lives of purpose and work for the public good.
