I'm currently applying for a postdoc position in a particular lab. The lab has several postdoc positions available at this time, those postdocs will work on different aspects of a larger research project.The application need to include statement of research interest, CV, references and recommendation letters in one document, and also clearly state which position (which aspect of the research) I apply for.
I feel I'm a good fit for two of the positions. However, I don't know how to write a statement of research interest that is suitable for both positions, although those two aspects of the research are connected. From all the examples I saw for research statement, future research is a big part of it. With the research direction and aspects are clearly defined for the positions, what should I write in the section of future research?
