Factors to consider:
* Your agreement with your supervisor: Did you enter into a formal or informal agreement regarding the duration of funding and your commitment to research? A written agreement is crucial. Breaking an agreement without sufficient justification could damage your reputation and future career prospects.
* The nature of the funding: Is the funding contingent on you completing your master's degree at that institution and potentially continuing on to a PhD there? Many funding packages imply an expectation of continued work.
* Your supervisor's expectations: Have you discussed your career aspirations and future plans with your supervisor? Open and honest communication is essential. They might be supportive of your exploring other PhD opportunities, especially if the program at their institution isn't the best fit for your research interests. However, they might also be disappointed or feel betrayed if you don't inform them of your intentions.
* Your research progress: How far along are you in your current research? Leaving abruptly might negatively impact the project and your supervisor's research group.
* Your reasons for applying elsewhere: Having strong and justifiable reasons for applying elsewhere (e.g., a better research fit, better funding, a specific supervisor you want to work with) will make the situation easier to navigate.
How to approach the situation:
1. Have a frank and honest conversation with your supervisor: This is the most important step. Explain your reasons for considering other PhD programs. Be prepared to discuss your commitment to your current research and your potential timeline for completing your master's degree.
2. Be transparent and respectful: Don't apply to other programs without informing your supervisor. This shows respect for their investment in you and avoids any potential misunderstandings.
3. Consider the consequences: Be aware that applying to other programs might jeopardize your current funding. Your supervisor might withdraw their support.
4. Develop a plan: Have a plan in place in case your application is successful. This includes a timeline for completing your current research, transferring any relevant data, and potentially working with your supervisor to transition the project to another member of the research group.
In summary, it's *not inherently inappropriate*, but it requires careful consideration and open communication with your supervisor. Transparency and respect for their investment in you are paramount. A proactive and honest approach is far better than a reactive one. Ideally, you should discuss your aspirations with them *before* applying to other programs.
