Long-Term Fellowships (LTF) are reserved for applicants with a Ph.D. in a biological discipline to embark on a new project in a different field of the life sciences. Preference is given to applicants who propose an original study in biology that marks a departure from their previous Ph.D. or postdoctoral work so as to learn new methods or change study system.
