My PI has just asked me what she should call me when introducing me to visiting researchers. I couldn't give her a definite answer.
I work in a research project where I supervise its research data in terms of versioning, formats, conversion, storage, etc. In this function I've, e.g., written a data management plan. I also (and this is the gros of my work) develop software which is used within the project but is also generic enough to target other researchers. And finally, I work on my PhD thesis, albeit not in a structured PhD programme (in my neck of the woods you can write a thesis as long as you have one or more supervisors with the right to supervise PhD theses.
As of now, I've usually been introduced as the "project's programmer", which my PI finds is somewhat dismissive of my actual work and responsibilities.
What would be a good title then, one that could also be printed on business cards?
