Joe Kesler
Ph.D. Student in Biology, admitted Autumn 2024
BioI am a Ph.D. student studying evolutionary ecology and biogeography in the Daru Lab. My research focuses on how species assemblages evolve and shift with changing environments across temporal and spatial scales. My current project integrates biogeographic analyses and phylogenetic data to understand the evolutionary and ecological forces shaping the biodiversity of the world's marine life.
In June 2023, I received a B.S. in Ecology, Behavior, and Evolution from UC San Diego, where I worked primarily with Professor Elsa Cleland, researching the demography of the California poppy (Eschscholzia californica) and how its traits vary across different climates within the state. I also participated in two other labs, broadly investigating plant-pollinator interactions and plant genetics respectively. After graduating, I assisted the Green Biome Institute at CSU East Bay by collecting DNA samples of endangered California plant species, followed by work as a habitat restoration technician for Recon Environmental in the marshes around the San Francisco Bay Area.
In the Daru Lab, I am excited to investigate how marine species respond to environmental changes over varied timescales, with the ultimate goal of informing habitat restoration management and conserving biodiversity worldwide. -

Alex Ketley
Advanced Lecturer, Dance
BioAlex Ketley is an independent choreographer, filmmaker, and the director of The Foundry. Formerly a classical dancer with the San Francisco Ballet and LINES Ballet, he left dancing professionally to create The Foundry as a platform to explore his interests in alternative methods of devising performance. The company has allowed Ketley the freedom to pursue projects that would be difficult to realize within his commissioning career. A few examples of these are: Syntax, an hour long duet systemically using the mechanics of language as an organizing mechanism; Lost Line researched how the application of environment affects the generation of movement and studied in direct response to California's diverse physical landscapes; Please Love Me jettisoned the structure of performing in a theater context and was developed with a curiosity about how people genuinely connect and experience artwork; the No Hero Trilogy which was a multi-year project that explored what dance and performance means to the lives of people living throughout rural America, and Distal Imprint was a film created in collaboration with artist and Death-Row inmate Bill Clark. The Foundry’s diverse work has been enthusiastically received by audiences, the press, and funders.
For his independent work as a choreographer he has been commissioned extensively throughout the United States, as well as projects in Germany and Italy, and has received acknowledgement from the Hubbard Street National Choreographic Competition, the International Choreographic Competition of the Festival des Arts de Saint-Sauveur, the Choo-San Goh Award, the Princess Grace Award for Choreography, four Maggie Allesee National Center for Choreography Residencies, the Gerbode-Hewlett Choreographer Award, the Eben Demarest Award, the National Choreographic Initiative Residency, a Kenneth Rainin Foundation New and Experimental Works Grant, three CHIME Fellowships, the Artistry Award from the Superfest International Disability Film Festival, and his work was featured on national television through an invitation from the show So You Think You Can Dance. His pieces and collaborations have also been awarded Isadora Duncan Awards for Outstanding Achievement in the categories of; Choreography, Company, and Ensemble, as well as nominated for Outstanding Achievement in Visual Design. In 2020 he became a Fellow of the John Simon Guggenheim Memorial Foundation, one of the most prestigious honors in the United States recognizing “individuals who have demonstrated exceptional creative ability in the arts”.
As an educator he has taught extensively throughout the country and currently holds the position of Advanced Lecturer at Stanford University’s Theater and Performance Studies Department. He was the founding Resident Choreographer at the San Francisco Conservatory of Dance for fourteen years until its closure in 2018.
Since 2020 he has been collaborating with his friend Bill Clark who is a prolific artist and writer that has been incarcerated on Death Row for the past 33 years. Alex invited Bill as a guest for his Stanford University class called DanceAcution: Performance Practice, Death Row, and the Evolution of Cultural Reform. The class used Bill’s vast experience as an artist and incarcerated individual as the platform for the students to develop new performance work. Bill is now collaborating with The Foundry on a new evening length work titled An Approximation of Resilience set to premiere in 2025. The project has won the prestigious National Dance Project Award from the New England Foundation for the Arts (NEFA) and generous support from the Luger Charitable Trust.
He is also on the Board of Directors of Death Penalty Focus, an organization whose work focuses on abolishing both the death penalty and LWOP (Life Without Parole). -
Kian Keyashian
Clinical Associate Professor, Medicine - Gastroenterology & Hepatology
BioThe management of inflammatory bowel disease continues to evolve, with the introduction of biologic and small molecule therapies and new goals of treatment, with an emphasis on healing the bowel. My career goal since my graduation from IBD fellowship in 2012 has been to improve the outcomes and quality of life of patients with inflammatory bowel disease. In line with these goals, my research has focused investigating new noninvasive diagnostic test, finding factors early in the disease course that might predict a more aggressive disease course and need for different therapies, and investigating new promising effective medications with less side effects.

Timothy Keyes
MD Student, expected graduation Spring 2027
Ph.D. Student in Cancer Biology, admitted Winter 2018
MSTP StudentBioTimothy is an MD/PhD student studying cancer biology and biomedical informatics at the Stanford University School of Medicine. He is a joint member of Kara Davis's laboratory in the Department of Pediatrics and Garry Nolan's Laboratory in the Department of Pathology.
As a biomedical data scientist, Timothy's research focuses on the application of machine learning to single-cell data analysis in the context of pediatric leukemia. Through the use of emerging, high-throughout single-cell technologies such as mass cytometry and sequence-based cytometry, Timothy's research is designed to build predictive models of patient outcomes - such as relapse or minimal residual disease (MRD) - at the point of diagnosis. To do so, he uses a variety of computational tools including generalized linear models, clustering, and deep learning. In addition, his work prioritizes constructing easy-to-use, highly-reproducible data analysis pipelines that can be shared as open-source tools for the scientific community.
Outside of science, Timothy has a longstanding interest in human rights and social justice work among members of the lesbian, gay, bisexual, transgender, and queer (LGBTQ+) community. He currently serves as the resident data scientist for the Medical Student Pride Alliance (MSPA), a 501(c)(3) non-profit organization that advocates for diversity, equity, and inclusion for LGBTQ+ medicals students in medical schools across the United States. As a data scientist at MSPA, Timothy analyzes and visualizes data to guide MSPA's strategic decision-making as well as for academic publication. He also advises and mentors other student members of MSPA performing data analysis in Python and R.
In recognition of his accomplishments, Timothy has received several institutional and national award for both research and advocacy. These include a National Research Service Award (NRSA) from the National Cancer Institute, a Junior Leadership Award from the Building the Next Generation of Academic Physicians (BNGAP) LGBT Workforce, Stanford Medicine’s Integrated Strategic Plan Star Award, and a Point Foundation Scholarship. -
