I’m starting my PhD this September in an Interdisciplinary degree that would fall in the realm of “resource economics” + “mathematical biology”. FWIW, I chose the interdisciplinary route because I want to carve out my own niche in the bioeconomics literature and my undergrad was in economics / math, my masters in renewable resource economics.
Speaking to my two supervisors, I was told I can bring a third advisor on that is not necessarily at my institution - and this offered a world of options to approach authors who’s works have encouraged me. However, while there’s so much benefit for me to have a third committee member from, say, the United States (my PhD is in Canada), it’s not clear to me what value there is for the third member. One of my supervisors is an established mathematical biologist, the other is an economist with a similar interest in bioeconomic modelling.
So I’d be curious to know, from an academic’s POV, if they were to be approached with something like this, where would the potential value proposition be for you? Keeping in mind that everything would be mostly virtual, and maybe at best case I could do a visiting appointment to work on collaborations.
