Please help me correct a closing speech? I was asked to write a closing speech for my supervisor in the dissertation defense. Please help me make it sound beautiful. Thank you so much! Ladies and Gentlemen, Thank you so much for taking time out to attend the dissertation defense for doctoral students of 2010. I also appreciate the presence of the dissertation committee and their invaluable comments. I remember Da vinci once said “Poor is the pupil who does not surpass his master”. I am just so glad that I did not see that happen here. All 4 of the doctoral students have done a great job in their study. I truly understand how much effort they have made and how much hardship they have been through. So they all deserve to be awarded a doctoral degree. Congratulations! Today is the day for them to enter into a real world and start a new career. I hope they can keep making progress and do their best to serve the patients. Once again, thank you all for coming. Good luck!
