The Three Sisters model is based on Indigenous American agricultural practices, in which three plants (corn, beans, and squash) are planted together in a shared space. They work synergistically to nourish each other and provide a sustainable, nutritional diet. The corn provides a tall stem on which the beans can wind around, the beans provide nitrogen to the soil for the corn and squash, and the squash grows wide leaves that shelter the soil to keep in moisture and keep out weeds. When harvested, they form a nutritional triad that can sustain a community.
This Three Sister project focuses on different aspects of higher education but all contribute to the larger goal of equipping graduate students to become more effective educators. Sister Project 1 focuses on the teaching graduate students do inside the classroom as teaching assistants. Sister Project 2 focuses on the role of graduate students outside of the classroom as researchers training undergraduates to be the next generation of graduate researchers. Sister Project 3 focuses on combatting imposter syndrome in graduate students so that they can show up in these roles as the full embodiment of their diverse experiences and identities.
Sister Project 1: TeachUp
At UC Davis, graduate Teaching Assistants (TAs) typically teach undergraduate students as part of their funding arrangements. However, many GTAs lack formal training and experience insecurity about their teaching capabilities. Serving as a GTA in the U.S., where intercultural competence is essential, can add to the challenges of delivering effective instruction. GTAs may also face struggle in balancing their dual roles as advanced learners and novice instructors. Therefore, adequate training for GTAs at UC Davis is critical to ensure high-quality undergraduate education, enhance teaching effectiveness, and reduce GTA’s anxiety associated with teaching experiences.
TeachUp is a training program for graduate teaching assistants (TAs) that combines peer mentoring (LinkUp & PairUp) and workshop series (StepUp) to build teaching confidence and adaptability in the U.S. academic, intercultural setting. The program is designed for first-time GTAs as well as both domestic and international TAs. The workshop series covers topics of activating lectures, imposter syndrome, effective communication, and stagecraft for teachers. First-time TAs will be paired with more experienced TAs who serve as mentors; they will share strategies and advice, and provide support as active listeners to their less experienced peers.

Sister Project 2: Guiding Community College Students Toward Research Opportunities
Exposure to the research process and access to mentors are crucial for becoming a successful applicant to graduate school and eventually, a successful graduate student. However, accessing research training and mentoring can be challenging for students whose parents did not attend college, are of low-income backgrounds, or belong to underrepresented populations. This project addresses this need by connecting local community college students to current UC Davis graduate students and guiding them through the process of applying to the Summer Research Early Identification Program (SR-EIP), run by the Leadership Alliance. Through this initiative, we aim to expand access to paid research internship opportunities and increase the level of graduate school preparedness of students from underrepresented backgrounds. The project consists of a four-part workshop series:
- Introduction to Research & The Leadership Alliance Program
- Writing Your Statement of Purpose
- Application Peer Review & Requesting Recommendation Letters
- How to Apply to Grad School & Graduate Student Q&A

Sister Project 3: Deconstructing Imposter Syndrome
Graduate students—particularly those who are first-generation, international, low-income, or from historically underrepresented backgrounds—often struggle with imposter syndrome and a sense of disconnection from their scholarly identities. These challenges emerge in both teaching and research settings, where students feel pressure to perform expertise while navigating internal doubts, hidden expectations, or a perceived gap between who they are and what academia demands. Yet students’ cultural histories, lived experiences, and embodied ways of knowing are powerful sources of confidence, insight, and pedagogical strength. When graduate students are supported in drawing from these assets, their teaching, research communication, and public academic presence deepen and become more authentic. Built on interdisciplinary approaches, this project consists of a three-part workshop series designed to help graduate students understand and reframe imposter syndrome through cognitive, embodied, and communicative practices:
- cognitive dimensions of imposter syndrome: identify internal narratives, understand the institutional roots of imposter phenomenon, and develop strategies for reframing academic belonging
- embodiment and performance: engage in guided exercises in breathing, rest, grounding, and attention to cultivate presence in academic spaces that resist urgency and support belonging
- public speaking: practice communication tools to strengthen graduate students’ clarity, confidence, and interdisciplinary communication skills
Wellness Kit Initiative
As part of our commitment to graduate and professional student well-being, participants are invited to contribute input toward a small, thematically aligned wellness kit that accompanies the series. The kit is built progressively across workshops and is designed to support reflection, grounding, and confidence.
Graduate and professional students may complete the optional Wellness Kit Survey here.
Cognitive Dimensions of Imposter Syndrome
Graduate students engage in collective reflection during the Cognitive Dimensions workshop at the Student Community Center.
