Back in 1996 I was fortunate to have the opportunity to move from Philadelphia to Scotland to carry out postdoctoral research with Professor Sir Philip Cohen in the MRC Protein Phosphorylation Unit. As an added bonus, I arrived at the birth of the GRE, and watched it grow exponentially over the next several years into an international research powerhouse.
My experience in Dundee, first in the Cohen lab and then with Professor Angus Lamond, has made a huge difference to my career at both the practical level (with exposure to a diverse range of skills, techniques and high-end equipment) and in terms of networking (with opportunities to share my work and collaborate with top-notch scientists at GRE and nationally/internationally). That is one reason that I would highly recommend it to any trainee considering the move.
The other reason is that Dundee is a fantastic place to live (and in my case, to also raise a young family). It is rare to find such a vibrant research community in an affordable city, and one that is only a short drive from so many wonderful places to visit.
