Inter-disciplinary nature of a PhD degree

The question of whether a PhD is inherently interdisciplinary is like asking if a tree grows leaves or roots – it’s both and neither at the same time. Let’s unpack this conundrum and see how PhDs can dance beautifully between the borders of disciplines. Imagine a library with towering shelves of knowledge, each section labeled with a discipline – history, physics, psychology, and so on. Traditionally, PhDs were like specialized librarians, mastering the intricacies of one particular section. They delved deep, becoming experts in their chosen field, their research confined to the well-defined boundaries of their library shelf.

However, modern research is increasingly challenging these neat divisions. Complex problems like climate change, artificial intelligence, or global health can’t be solved by just one librarian stuck in their own section. They require a team effort, experts from different shelves collaborating to piece together the bigger picture. This is where the interdisciplinary PhD steps in. Think of it as a librarian wearing a magical pair of glasses that lets them see across the entire library. They can still delve deep into their own section, mastering the knowledge within. But they can also peek at other shelves, borrowing tools and insights from different disciplines to enrich their research.

For example, a PhD student studying the impact of climate change on ancient civilizations might combine historical analysis with environmental science and anthropological studies. They’d be a librarian comfortable navigating the history, geology, and social science sections, piecing together a richer understanding of this complex issue.

So, are PhDs inherently interdisciplinary? Not necessarily. There are still plenty of “single-shelf” PhDs, focused on pushing the boundaries of a specific field. But the trend is undeniable – more and more research problems demand a broader perspective, a willingness to borrow tools and insights from across the library.

Here are some ways a PhD can be interdisciplinary:

  • Multidisciplinary: Combining two or more established disciplines, like a PhD in neuroscience and computer science investigating how the brain processes information.
  • Transdisciplinary: Blending existing disciplines and creating new frameworks, like a PhD in sustainability studies bridging environmental science, economics, and social policy.
  • Problem-driven: Focusing on a specific issue and drawing from any relevant discipline to solve it, like a PhD in public health addressing food insecurity by combining nutrition science, social work, and economics.

But there are also challenges to being interdisciplinary:

  • Finding advisors: It can be tricky finding mentors who are comfortable navigating across different fields.
  • Communication hurdles: Using language and concepts understood by experts from various disciplines.
  • Funding complexities: Funding agencies may prefer research neatly categorized within traditional disciplines.

Despite the challenges, the benefits of interdisciplinary PhDs are undeniable. They equip graduates with a unique skillset, making them adaptable and innovative thinkers capable of tackling complex problems. Their research contributes to breaking down disciplinary silos, leading to new discoveries and solutions that wouldn’t be possible by staying within the confines of a single shelf.

So, to answer your question, whether a PhD is interdisciplinary depends on your approach. The library of knowledge is vast, and while some choose to master one section, others embrace the freedom to explore, borrow, and connect across the shelves. If you have a research question that begs for a broader perspective, an interdisciplinary PhD might be the perfect path for you, allowing you to become a librarian with a truly panoramic view of knowledge.
