Should an interdisciplinary researcher work twice as hard? My Ph.D. research is related to both computer-science and economics. I collaborate with researchers in both these disciplines, and naturally submit papers to journals of both disciplines. Now, while looking for an academic job, I find out that departments count only the publications published in journals of their own discipline. This is true both in the acceptance decision and in the tenure decision. So, whether I go to CS or to economics department, in expectation, I have only half the number of counted publications of a one-discipline researcher. What can I do about it?


One option is to choose one of the two disciplines and only send papers to its journals. But, this means I will have a hard time collaborating with researchers from the other discipline, since they will probably want to publish in "their" journals.
Another option is to work twice as hard and publish twice as many papers. 


Is this true that an two-disciplinary researcher should work twice as hard to attain the same career status as a one-discipline one?
I collaborate with, and work on projects, involving human health, animal health, ecology, and the occasional bit of applied math.

Should I work four times as hard?

The simple answer is no. Because it's both impossible, and rather unlikely that you're even capable of that.

Instead, the answer is unfortunately that if you wish to be doing interdisciplinary research you should not be looking at those departments.

Because not all departments do this. Right now, my unit is hiring people working in health economics, and we've been very mindful to put their work in the appropriate context, including asking field experts what "counts" for them. We're doing similar things with other people we are hiring - for example, right now, we have representatives from at least three departments sitting on a committee for interdisciplinary hires.
