Data Analysis

12. Training sessions  Free training sessions to members affiliated with the NPOD Enhance the research expertise in members’ laboratories. To develop an epigenetics workforce in Nebraska.  Investigators from other institutions: Develop more formalized training sessions (and charge a nominal fee). Services

13.  Priority Junior Investigators > Other center members > External users  Fee Structure Each JI : $2,000 credit /year of project funding. Remaining credit: Carry forward to the next year. Transfer to another center member.  Once the credits are exhausted JIs will be required to pay a fee that covers the cost of supplies, etc.  The same fee will be paid by other center members and external users.
