I strongly believe in promoting and encouraging diversity, equity, and inclusion (DEI) in STEM, and particularly in the fields of evolutionary biology and ornithology. As someone that occupies many non-majority backgrounds (e.g., first-generation college student, woman, Latinx, low SES) and received integral encouragement and support along the way, I work hard to give back from the other side.

Readings on DEI in Science

I am actively collating a list of resources on diversity, equity, and inclusion in the sciences (and academia more broadly). These include shorter blogpost-style articles and published literature. Feel free to use this list for courses, websites, or personal reading! Visit Readings on Diversity in Science to see the list.

DEI-related Research

I conduct research in a variety of settings to understand how both our everyday science “culture” and specific interventions influence people from diverse backgrounds. In particular, I have worked to understand how specific teaching strategies and large-scale interventions influence women and underrepresented minority students in STEM.

Diversity Preview Weekend (DPW)

Cornell graduate students in Ecology and Evolutionary Biology (EEB), Entomology (ENTO), and the School of Integrative Plant Science (SIPS) co-organize an annual event to bring first-gen and underrepresented minority students to Cornell before they apply to graduate school. Attendees participate in various workshops, network with faculty and current students, and learn about the application process. Visit for more details on the program.
