Awais Khan (born 1977) is a Pakistani-American plant geneticist and an associate professor at the College of Agriculture and Life Sciences, Cornell University.[1][2]

His research focuses on genetics of disease resistance in apples,[1] crop improvement, sustainable agriculture, and food security.[2] Prior to taking this position, he was leading a global research program on genetics of adaptation and abiotic stress tolerance in potatoes and sweetpotatoes, at the International Potato Center (CIP), Lima, Peru[3][4].

Biography

[edit]

Khan was born in a small village called Tahlian in Pallandri, Azad Kashmir (the Pakistani-administered part of the disputed Jammu and Kashmir region) and was from a humble financial background. His primary-level education was at a "taat school," where the students sat on a jute mat (taat) on the ground and he also helped his parents raise crops and livestock.[2]

He earned a PhD from the Swiss Federal Institute of Technology (ETH), Zurich, Switzerland on fire blight of apples, and an MSc from Georg-August University, Gottingen, Germany, with further research experience at the University of York, UK and University of Illinois, Urbana-Champaign, United States.[1][2]

He has published in several high impact scientific journals including Science, Nature Genetics, and Genome Research.[5] His research on rapid decline of apple trees, fire blight, genetics, and genomics of apples has been also highlighted in popular magazines, including Science Magazine, The Economist, New York Times, and Forbes.[6][7][8][2] In 2022, Dr. Khan co-led a research and completed a chromosome-scale genome sequence assembly of Honeycrisp apples.[9][10]
