The NAG website has a section called "Meet our experts - NAG out and about", which gives a list of upcoming events worldwide that NAG experts will be attending or presenting at.
The page also notes: "We regularly organise and participate in conferences, seminars and training days with our customers and partners. If you would like to talk to us about hosting a NAG seminar at your organisation or any training requirements you might have email us at firstname.lastname@example.org".
In my own focus of High Performance Computing (HPC), I have previously written (for ZDNet UK) about some key supercomputing events. For those of you interested in meeting up with HPC experts (especially from NAG!), I have set up a survey of HPC events - please let us know which events you plan to attend in 2011 - and see which events other readers of The NAG Blog are attending.
