I am about to embark on a project to setup an section of Marine Protected Areas in Madagascar. The project itself is already funded and I am working with two separate NGO's on the project. I would like to be able to start my PhD on something related to reef resilience and know a number of people that could be potential supervisors. I would like some advice on whether people think it would be feasible to conduct a PhD alongside a job where I am based in the field (pretty much out of contact) for a large proportion of the next 2 years?
