Iñigo San Millán's research focuses on mitochondrial performance and efficiency across exercise metabolism, nutrition, sports performance, overtraining, diabetes, cancer, and critical care.

“where his areas of research focus on exercise metabolism, nutrition, sports performance, overtraining, diabetes, cancer, and critical care. And I realize at least one of you at this moment is thinking, how in God's name can one person study all of those things? And the answer is, if you come at it through the lens of the mitochondria, it turns out you can have a breadth of focus that covers all those things. And of course, that's exactly what Inigo does is he studies mitochondrial performance and mitochondrial efficiency.”
