Abstract This proposal is for a new T32 predoctoral program to train the next generation of multi-disciplinary cancer researchers with the expertise to unravel the complexity of factors underlying cancer risk and disparities. The rationale for this T32 is to bridge the gaps between cancer research fields with integrative education and holistic professional development. The T32 leverages strengths of Stanford University and the Silicon Valley to provide specialized cancer-focused training across traditionally distinct fields. The program blends in a highly interactive fashion training opportunities in coursework, seminars, internships at Stanford University and local biotech companies, and mentored research projects. Coursework and seminars include core offerings newly developed for this program. Trainees will learn the methods and technologies used in foundational disciplines of cancer research: epidemiology, biostatistics, genetics, omics, environmental health, health disparities, and community- engaged research. The program will also train students with the concept of “cells to society,” the complex interplay between biological, social, and environmental factors that shape health outcomes at both the micro and macro levels. This approach recognizes that health is not solely determined by genetics or individual behaviors but is also influenced by the social and environmental contexts in which individuals live, work, and interact. The T32 is designed to train students in diverse skill sets, such as novel research methods, data analytics, as well as soft skills like communication, teamwork, and leadership. This framework provides rigorous training, which will be underpinned by the principles of responsible research conduct. Drs. John Witte and Melissa Bondy lead the program having overseen multiple previous training programs and with decades of successful experience training the future generation of cancer researchers. The T32 mentoring team is comprised of 26 outstanding faculty members with cancer-focused research projects across multi-disciplinary fields. The program has extensive financial and administrative support for trainees from Stanford University and the Stanford Cancer Institute, rigorous student advising, and 360-degree evaluation among the trainees, mentors, an internal executive committee, and an external advisory committee. By integrating multi-disciplinary approaches, the T32 has a strong foundation in which trainees develop the skills vital for furthering their careers in research to decipher the causes of cancer and underlying disparities, ultimately providing valuable knowledge regarding the prevention and equitable treatment of this common, but complex disease.
