The CRM Early Career Executive Council (ECEC) consists of early career leaders in the field of regenerative medicine that are appointed on a yearly basis, with potential for renewal for up to 3-years. Council members include graduate students, postdoctoral fellows, and staff that are currently appointed in CRM labs. ECEC members are provided with an honorarium at the end of each year.
Goals of the ECEC are set in collaboration with the Directors and Staff of the CRM and may include the following:
- Advise the Directors of the CRM on the needs of the in-training members of the Center
- Design and lead the implementation of yearly CRM networking and training events
- Contribute to and inform center communications including newsletters, social media, and outreach
