I would have emailed him when you submitted the app, so if you just submitted than yes. If it’s been several weeks since the deadline, I’d probably advise against personally
What I did was email my POI telling them I sent the application and thanking for them for all the help they gave me in the process. Simple and quick to the point.
However, if it's been weeks since you applied (if you applied the 14th of November), it might come across as you trying to basically get them to look at your application. I'd also advise if it's been that long (unless its the 14th of this month, in which case contacting them to inform them and thank them shouldn't be a problem).
