Hi!
I don’t think the field of study matters that much — it really depends on what you’re genuinely interested in. I actually have a few fascinating academic figures I’d love to introduce to you. Have you heard of Gary Gereffi? He’s basically the godfather of global value chains (GVCs). His research touches on business–government relations, industrialisation, international trade, engineering outsourcing, innovation, and commercialisation. You’d probably assume he has a background in some business-related field, right? But no, he holds a PhD in Sociology. Another example is Jeremy Moon, a leading figure in corporate social responsibility (CSR). He used to teach at Nottingham (though I think he’s moved elsewhere now), and he helped establish one of the UK's largest CSR research centres there. Would you believe he earned his PhD in Politics? And then there’s Peter Dicken, the go-to expert on globalisation and transnational corporations (TNCs). At first glance, you’d think he studied economics. But actually, he has a PhD in Geography, and he’s considered one of the most influential economic geographers in the discipline over the past 30 years.
Let’s take a look at the field you mentioned in your post. One great example is Antonio Andreoni, who teaches at SOAS. He earned his PhD in Development Studies, but his thesis and research focus on manufacturing development and topics related to the production sector. A similar case is Jostein Hauge, who also holds a PhD in Development Studies. His research deals with industrialisation, manufacturing, and automation. These two scholars show that you don’t necessarily need a degree in industrial engineering to work in this field. Moreover, what both of them do share, though, is that they approach their work from a political economy perspective.
Now let’s circle back to King’s College London. I actually have a few more interesting, and slightly amusing, examples of younger scholars to share. Take Kyunghoon Kim, for instance. He earned his PhD in Development Studies, but his research is mainly in political economy and economic policy. On the flip side, there’s Bryan Cheang, who holds a PhD in Political Economy but focuses most of his research on development-related topics. It all feels a bit paradoxical, doesn’t it? (Haha) Oh — and one last person worth mentioning is Tao Zou, a PhD candidate in the Department of International Development. His research involves multinational enterprises (MNEs), foreign direct investment (FDI), and he’s also affiliated with the Academy of International Business. On top of that, he has work experience with the United Nations Conference on Trade and Development (UNCTAD). He clearly has a strong interest in international business and trade, but as his case shows, pursuing a PhD in a Business School isn't the only path forward.
Anyway, I’m not sure how helpful this comment will be, but I hope it adds something to the conversation!
