“Long term, I would like to come back to New Zealand to work clinically and in the medical school while continuing my interests in public health and policy. I have family in Dunedin and love working with students.” His future work may be among a growing group of doctors and researchers who are working to connect links between the US, Australia and the Pacific area. “I’ve been working with many of the New Zealanders who are based in the United States and there is a strong desire to leverage existing resources and efforts, and link US-based medical alumni back to New Zealand. “I’ve benefitted from so many opportunities during my career, so a lot of what I do now is about opening the door for others coming through.” Away from medicine, Walker enjoys spending time with his wife and two young children, and competing in long-distance running events, including the New York City Marathon, which he has completed five times (with a best placing of 89th overall), and the Boston Marathon, which he has run six times.
