I have just been given a dataset, and hopefully the money to hire a post doc to analyze it. The data set requires a post doc with experience in health informatics. No one in my deptartment, including myself, has experience with health informatics. The dataset is about 4 orders of magnitude bigger than anything anyone I know has looked at, and 2 orders of magnitude bigger than the largest published datasets in my field. How do I go about recruiting and hiring a post doc in an area outside my expertise?
