Roderick MacKinnon won the 1999 Lasker Award for elucidating the structure of potassium channels. His work provided the first molecular description of an ion selective channel and helped knock down what he called “psychological barriers” in the field. After MacKinnon, the structure of transmembrane ion channels went from being seen as unsolvable to solvable.

In this 1999 interview with Chris Miller, Professor of Biochemistry at Brandeis University, MacKinnon shares anecdotes from his early career, discusses how the field reacted to his groundbreaking work, and talks about what motivates him scientifically.
