Collaborating Investigator
A collaborating investigator contributes in a substantive way to the scientific development or execution of the project. Typically, a collaborating investigator has a doctoral or other professional degree and devotes a specific percent of effort to the project. For certain AHA programs, an applicant will identify a collaborating investigator.

A consultant contributes to the scientific development or execution of the project in a discrete way. Typically, a consultant has a doctoral or other professional degree. A consultant may provide discrete services which are performed in a limited window of time or occasionally contribute a specific method/technique/analysis or materials for the project.

Other Professional
An Other Professional is an individual who may hold a doctoral, masters or baccalaureate degree or its equivalent and who is considered a professional. Examples of persons included in this category are analysts, biostatisticians, computer programmers, veterinarians, nurse coordinators, epidemiologists, etc.
