Universities promote interdisciplinary research in strategic plans, funding proposals, and recruitment materials. Yet when professors actually try to collaborate across disciplines, they encounter a reality that is far more complicated than the rhetoric suggests.
A 2026 study published in Written Communication found that while 75% of faculty at a large research university supported interdisciplinary initiatives, only 31% believed current institutional structures enhanced such work. The researchers identified five key obstacles: structural barriers, career concerns (particularly for pre-tenure faculty), disciplinary cultural differences, terminological conflicts, and divergent goals between faculty and administrators.
These are not new problems. What is new is that solutions are beginning to emerge.
The Five Barriers, Explained
1. Structural Barriers
Most universities are organized around departments that control budgets, hiring, and space allocation. Cross-departmental collaboration requires navigating multiple administrative systems, and credit for joint work is often poorly allocated.
2. Career Concerns
For pre-tenure faculty, interdisciplinary work carries real risk. Tenure committees are typically composed of disciplinary experts who may undervalue work published in journals outside the candidate's home field. Publishing an interdisciplinary paper in an interdisciplinary journal may count for less than a single-discipline paper in a top disciplinary journal.
3. Disciplinary Cultural Differences
Different fields have different norms for authorship order, methodology, writing style, and even what constitutes evidence. These differences are manageable but require explicit negotiation — time and effort that many collaborations do not invest upfront.
4. Terminological Conflicts
The same word can mean different things in different disciplines. "Model" means something different to a mathematician than to a social scientist. "Impact" is measured differently in public health than in engineering. These conflicts are subtle but can derail collaborations if not addressed early.
5. Discovery Failure
Perhaps the most fundamental barrier: professors often do not know who at other institutions — or even at their own university — is working on problems relevant to theirs. The discovery problem is structural, not personal.
What Is Changing
Three developments are beginning to address these barriers:
Purpose-built networking platforms like Know Your Faculty are attacking the discovery problem directly. By matching professors based on research-fit scores rather than institutional or departmental proximity, they surface potential collaborators that traditional channels miss.
Funding bodies are incentivizing cross-disciplinary teams. Programmes like the British Academy's Knowledge Frontiers and the NSF's convergence research initiatives explicitly require interdisciplinary and often international collaboration. This creates both motivation and funding for professors to seek collaborators outside their discipline.
Institutional policies are evolving. Some universities are beginning to revise tenure guidelines to explicitly value interdisciplinary contributions, create dedicated funding for cross-departmental pilots, and establish facilitated networking opportunities.
The Gap Will Not Close Itself
The 44-percentage-point gap between wanting interdisciplinary collaboration and having structures to support it is a systemic problem that requires systemic solutions. But individual professors do not have to wait for their institutions to solve it. The tools to discover collaborators across disciplines exist today — the question is whether professors use them.
