Irah King, PhD, is known as much for his thoughtful presence as for the impact of his work. As Director of the ºÚÁÏÍø±¬³Ô¹Ï Centre for Microbiome Research, Professor in the Department of Microbiology and Immunology, and Microbiome Theme Lead within MI4, he has played a defining role in shaping microbiome research at ºÚÁÏÍø±¬³Ô¹Ï – well before stepping into his leadership role nearly seven years ago.
Bringing together people, ideas, and disciplines, Dr. King and his dedicated colleagues have helped to grow the Centre into a vibrant, collaborative hub for innovation.
We spoke with him about his journey, the evolution of the Centre, and why collaboration sits at the heart of scientific discovery.
You began your work in microbiome and immunity research years before establishing the ºÚÁÏÍø±¬³Ô¹Ï Centre for Microbiome Research. Looking back, how did that early project evolve into a full Centre – and what role did MI4’s support play in that journey?
Microbiome research really took off with advances in DNA sequencing – tools that are far more powerful than what we had even 20 years ago. Suddenly, we could see what microbes were actually there.
My background is in mucosal immunology, so I was interested in how the microbiome was influencing immune responses in the gut. Instead of asking what’s there, I focused on what it’s doing.
But those questions quickly became bigger than any one field. Around 2015, we started building collaborations across ºÚÁÏÍø±¬³Ô¹Ï, and it became clear that people needed shared tools and expertise. That’s what led to the idea of creating a central hub.
With strong support, especially from MI4, we were able to build the Centre from the ground up, bringing different kinds of expertise together in one place.
MI4 partnership has helped the Centre grow its platforms, like the Gnotobiotic Animal Research and Microbial Services Platforms. How has that support expanded the Centre’s capacity to enable innovative microbiome research at ºÚÁÏÍø±¬³Ô¹Ï and beyond?
Put simply, these platforms wouldn’t exist without MI4. The support we received from MI4, ºÚÁÏÍø±¬³Ô¹Ï, and the ºÚÁÏÍø±¬³Ô¹Ï Health Centre, went far beyond funding. We benefited from strategic guidance and ongoing advocacy. Building a Centre like this takes time and commitment, and that support made it possible to grow in a way that was both thoughtful and (hopefully) sustainable.
As the infrastructure came together, it opened the door to new collaborations and stronger science. Now, a few years in, we’re really seeing the impact: researchers are using these platforms to make exciting discoveries, secure grants, and publish their work.
In that sense, the return on investment has been significant not just financially, but in the strength of the research community we’ve built.
As Director, what has surprised you most about the impact the Centre has had, both scientifically and for the researchers and trainees who use its resources?
One of the most striking outcomes has been the role we’ve played in advancing research on the microbiome’s contribution to chronic pain syndrome. Supporting studies and publications in this area has been particularly rewarding.
At the same time, the scope of research continues to expand. We’re now supporting projects in cancer, early-life development, infection, and vaccination, among others. What stands out most, however, is the extent to which the Centre has enabled truly multidisciplinary research. Investigators from different fields are coming together in ways that weren’t happening before, and that collaborative growth is one of our most important achievements.
If you could capture the evolution of the ºÚÁÏÍø±¬³Ô¹Ï Centre for Microbiome Research and MI4’s partnership in one sentence, what would it be?
Providing resources leads to collaboration that leads to innovation.
In many ways, that simple statement captures the philosophy behind the Centre itself: bringing together people, expertise, and infrastructure to fill research gaps that no single discipline could address alone.
And as microbiome science continues to evolve, it is precisely this collaborative spirt, supported by ecosystems like MI4, that is helping push the boundaries of discovery.
