When to use academic titles in presentations in Europe? I have M.Sc. (tech.) in physics. I am doing second degree in MD. I normally just present my work without academic titles in MD studies. 
I am thinking the benefits of using academic titles in different fields. 
Some of my friends use MD in medical stuff, while M.Sc. (tech.) in technical stuff. 

However, many times, I have to deal with epidemiology and statistics where I use tools in Physics. 
In these cases, I am thinking if I should use the academic title because my work is so different than anyone else in the group. 
Same goes for the reports which I write. 

In Finnish culture, we do not want to emphasize what you have achieved, which is the reason I am not using the academic title. 
However, I am not sure about it.  

Other titles which I can use EUR ING soon. 
I think it is extraneous in such presentations. 
Not sure which are the rules when to use this one, for example. 
I think it is enough to leave the latter in CV.
If I understood correctly, you live in a culture where flaunting one's title(s) comes across as a bit crass; at the same time, you wonder if mentioning your title on the first page of a powerpoint presentation might increase your credibility when you are presenting to certain audiences.  (Did I get that right?)

You may be able to get the idea across in a more subtle way, that people would not interpret as bragging, on the first or second slide, as an acknowledgment.  For example, you could acknowledge the mentorship of Prof. XX in the YY Master's program at ZZ University.

That's just an example.  Does it give you some ideas?
