Part 2 of this PREP course will be held on Tuesday, January 7th of 2014.
The Public Research Education Program (PREP) is a series of courses developed by various research support offices in conjunction with other health system offices. The courses offer CME credits and are designed to increase quality of research throughout the health system and streamline the process of conducting research.
PREP courses also aim to enhance and expand investigator capacity to conduct research. PREP courses are free and open to all North Shore-LIJ employees, students, and volunteers. In addition, interested research collaborators and community partners are welcome to attend.
Light refreshments will be served at the courses held at the Goldman B Conference Room.
Don’t forget to check out select videos of PREP courses online.
