Thank you for the feedback, I appreciate the clarification. I understand, maintaining appropriate professional boundaries in communication with authority figures like professors can be tricky to navigate.

Some suggestions could be:

- Replacing "it would be great to catch up" with a more neutral phrase like "I hope you've been keeping well."
- Removing that part of the sentence altogether and ending on "I look forward to hearing back from you."
- If you do want to express interest in their work or life, a more formal phrasing could be "I would appreciate any updates on your recent work or activities, if you have the time."

Does any of these options work, or would you like other suggestions? Please let me know if you have any other concerns or feedback on the email. I'm happy to refine it further.
