Pilot Funding Support

 

Core Pilot Program

The Biostatistics Core participates in the CHLA Pilot Program. 

At CHLA, our Core Pilot Program exists to supply funding support for investigators to acquire preliminary data to provide a competitive edge for securing extramural grant funding. This program is one of a number of institutional investments to grow the research portfolio of the CHLA research enterprise.

A core pilot project is defined as a short-term project to develop an applicable preliminary data set to be used in the process of developing an extramural grant proposal for submission. Pilot data also is useful for determining sample power and demonstrating data quality. Pilot project funding is not to be used for full-scale research projects or to supplement existing funded awards.
