I do know that many of my faculty colleagues do have international collaborations, but it is also hard to know. Having worked in the NIH a little bit as well, with grant funds from there, they actually tend to be a little more insular and have fewer international collaborations.
However, I believe there is certainly space for trying to develop, identify, and then scale up effective strategies or policies much more quickly than is done now. I know that CIHR effectively tries to implement a knowledge translation component into each research project. However, I think there is a central role that could be played in identifying effective strategies, pushing them out, and scaling them up with resources much more quickly than leaving it to individual investigators or researchers such as myself, where the payoff in terms of my time disseminating research, rather than creating it, is very low.
So I think there's a role for central agencies to identify good ideas, evaluate them, and scale them up.
