PROJECT ABSTRACT Networking Core The overarching goal of the UCSF LAUNCH (Learners to LeAders in benign Urology, benign Nephrology, and non-Cancer Hematology) Program is to train, mentor, and support promising junior investigators from diverse disciplines who are interested in pursuing careers focused on areas of investigation within the mission of the NIDDK. In support of this goal, the Networking Core will develop systems and processes that support direct peer communication and near-peer mentoring among all trainees who are supported by the TL1 Core. Our networking reach will also include institutional trainees already supported by other funding mechanisms who are working in adult or pediatric nephrology, urology, and hematology across our four institutions. We have designed a comprehensive networking program that includes didactic and experiential learning as well as extensive opportunities that will: (1) generate highly interactive opportunities for trainees to learn from peers and near-peers within a close-knit community that is ready to provide support, advice, and peer mentorship; (2) support and nurture strong relationships between trainees to maximize research productivity and trainee well- being and satisfaction; and (3) facilitate access of trainees to vertical mentorship and key faculty who represent a network of outstanding scientists, teachers, and mentors and who are collectively tackling problems related to adult and pediatric diseases using basic, translation, and clinical research methodologies. In addition, the Networking Core will actively engage high school and undergraduate institutions within Northern California to broaden their exposure to nephrology, non-malignant urology, and non-malignant hematology and develop a robust pipeline of individuals who may be interested in pursuing research within these disciplines. We will pay particular attention to our outreach to individuals who are traditionally under-represented in the sciences. Our Networking Core will be led by Dr. Marsha Treadwell, Professor in the Division of Pediatric Hematology at UCSF and Dr. Vivek Bhalla, Associate Professor in the Division of Nephrology at Stanford University, who both have a wealth of experience in training researchers and in networking.
