Peter John Hudson

Peter John Hudson (born 1953) is a British population ecologist known for his work in wildlife disease ecology. He is the Willaman Professor of Biology at Pennsylvania State University and formerly served as Director of the Huck Institutes of the Life Sciences from 2006 to 2019.

Early life and education

Hudson earned a BSc (Hons) in Zoology from the University of Leeds in 1974. He completed his D.Phil. in Zoology in 1979 at Magdalen College, Oxford, in association with the Edward Grey Institute of Field Ornithology at the Department of Zoology.

Career

After completing his doctorate, Hudson joined the Game & Wildlife Conservation Trust (GWCT), where he researched red grouse population dynamics in northern England and Scotland. In 1985, he was appointed Reader at the University of Stirling and later received a Personal Chair in Wildlife Disease Ecology. He moved to Pennsylvania State University in 2002, where he continues to work in the Department of Biology.

Hudson's research has focused on infectious disease ecology in wildlife; his work has examined the influence of parasites on population cycles in species such as red grouse and the effects of shared infections on community structure and includes how infections can drive competitive exclusion and local extinction. He has also investigated how parasitic infections increase the vulnerability of animals to predation, known as the healthy herds hypothesis.

In addition, Hudson has contributed to studies supporting the dilution effect, a hypothesis proposing that greater biodiversity can reduce the rate of pathogen transmission. He examined the dilution effect by examining the persistence of tick-borne viruses in multi-host systems. More recently, his research has addressed the drivers of zoonotic disease spillover, including a 2023 study published in Nature on how climate variation leads to bats moving into urban areas and shedding virus. This was followed by a 2024 article in Nature Communications on ecological countermeasures to prevent spillover and outbreaks.

Hudson has participated in several scientific expeditions, including the 1974 Zaire River Expedition led by John Blashford-Snell, where he studied insect distribution ecology, and Operation Drake in Panama in 1979.

Hudson has received several honors for his contributions to ecology and wildlife disease research, including:
