Euan Angus Ashley is a Scottish physician, scientist, author, and founder based at Stanford University in California where he is Associate Dean in the School of Medicine[1] and holds the Roger and Joelle Burnell Chair of Genomics and Precision Health.[2] He is known for helping establish the field of medical genomics.

Education and early life

[edit]

Ashley was born and raised in the West of Scotland and attended Kelvinside Academy in Glasgow. As a teenager, he programmed computers and read popular science books on genetics. He studied Physiology and Medicine at the University of Glasgow graduating with 1st class Honors. He completed residency training at the Oxford Deanery[3] and received his Doctorate (DPhil) from the University of Oxford (Christ Church College). At Stanford University in California, he completed post-doctoral research and specialized training in cardiology, joining the faculty in 2006. He was appointed Associate Dean in 2020.

Research

[edit]

Genomics

[edit]

Ashley is best known for his study of the human genome.[4][5][6][7] In 2009, he led the team that carried out the first medical interpretation of a human genome.[4] The work published in The Lancet laid out a general framework for the medical analysis of a complete human genome and applied this framework to the genome of his Stanford colleague, Stephen Quake. Quake had invented a technology to sequence his own genome, becoming the fifth individual in the world to be sequenced. The landmark medical analysis was reported in news media internationally and was later featured in the Smithsonian museum.

In 2010, Ashley's team carried out the first whole-genome molecular autopsy[8] generating data from the same Helicos sequencing technology of post-mortem cardiac tissue from a patient who died suddenly at a young age of presumed cardiac cause.

In 2011, his team developed a framework for family-based medical genome analysis.[9] The West family were the first family to have their genomes sequenced and were four of the ten individuals sequenced as part of Illumina’s personal genome sequencing project. Other individuals in this first group of ten included Illumina CEO Jay Flatley and the actress Glenn Close. The computational tools developed by Ashley's team included inheritance tools for mendelian diagnosis in trios and quartets, family based polygenic risk scores, whole genome phasing, HLA typing, and automated star-allele calling for pharmacogenomics.

Over the following years, Ashley's team helped establish genome sequencing as a fundamental tool for diagnosis in clinical medicine. In 2014, they reported in the Journal of the American Medical Association a study of genome sequencing in primary care, demonstrating early detection of pathogenic variations in the breast and ovarian cancer gene BRCA2, and delivering tools for cardiometabolic polygenic risk scoring, and pharmacogenomics. This work also introduced quality-coverage metrics. Ashley was interviewed for NPR's Morning Edition.

In 2017, Ashley's team made the first medical diagnosis using long-read sequencing in a patient with Carney complex whose targeted Sanger sequencing and short read whole genome sequencing had been unrevealing. Developing a pipeline for clinical diagnosis based on aligning, variant calling and filtering Pacific Biosciences SMRT sequencing data, the team identified a previously unrecognized 2 kilobase deletion in PRKAR1A, the gene responsible for Carney complex.

In 2018, as the first co-chair of the steering committee of the Undiagnosed Diseases Network (UDN)[10][11] Ashley led the network's analysis published in the New England Journal of Medicine that reported an overall diagnosis rate of 35%, estimated significant cost savings from early application, and defined 31 new medical syndromes. This was reported widely including on CBS This Morning, NPR's Morning Edition, and the New York Times where it featured in a segment titled This Week in Good News.

In 2022 Ashley and his research team developed ultra-rapid nanopore genome sequencing for critically ill patients.[12] Published in the New England Journal of Medicine and Nature Biotechnology, the team showed that a genetic diagnosis from whole genome sequencing was possible in as little as 7 hours and 18 minutes.[13][14] This achievement was recognized by the National Institute for Standards and Technology as well as by Guinness World Records who awarded the team a new record for “fastest DNA sequencing technique.”[15] Ashley appeared on NBC Evening News to discuss the findings.

Cardiovascular science

[edit]

Ashley's group has also contributed to the foundational science underlying the development of heart transplant donation after cardiac death (DCD) much of that work performed in the same building at Stanford in which heart transplantation was first developed by Norman Shumway.

Awards and honors

[edit]

Ashley is a recipient of the National Innovation Award from the American Heart Association (AHA) as well as the National Institutes of Health (NIH) Director's New Innovator Award. In 2017, he was recognized by the Obama White House for contributions to personalized and precision medicine. In 2019, he was awarded the American Heart Association Medal of Honor for Genomics and Precision Medicine. In 2021, he became the first holder of the Roger and Joelle Burnell Chair in Genomics and Precision Health at Stanford University. In April 2023, he was awarded the Guggenheim Fellowship,[16][17] a prestigious honor recognizing mid-career scholars, artists, and scientists who have demonstrated a previous capacity for outstanding work and continue to show exceptional promise.

Scientific publications

[edit]

Ashley has co-authored over 400 peer reviewed publications.[18]

Books

[edit]

Cardiology Explained

[edit]

In 2004, Ashley published the textbook Cardiology Explained[19] along with co-author Josef Niebauer (Remedica, London). According to the publisher's notes, the title “...explains the basic physiology and pathophysiologic mechanisms of cardiovascular disease in a straightforward and diagrammatic manner, gives guidelines as to when referral is appropriate, and, uniquely, explains what the specialist is likely to do.”

The Genome Odyssey

[edit]

Ashley released the non-fiction title The Genome Odyssey: Medical Mysteries and the Incredible Quest to Solve Them [20][21] on February 23, 2021, with Celadon Books, a division of Macmillan Publishers. The book features stories of patients and families from Ashley's medical practice and walks through the science underlying those diseases, shining a spotlight on some of the scientists. New York Times best-selling author Abraham Verghese remarked that The Genome Odyssey was “destined to be a landmark narrative in the canon of modern science.” The Pulitzer prize winning author Siddartha Muhkerjee wrote that “Dr Ashley, one of the pioneers of gene sequencing technologies, writes with authority, elegance and simplicity.” The Wall Street Journal described The Genome Odyssey as an “impassioned, firsthand account of the effort to bring genomic data into clinical practice.”

Media

[edit]

Ashley has appeared on National Public Radio in the United States as well as the BBC radio, Japanese and Indian national television, and NBC Evening News. His work has been covered in print by The New York Times, The Wall Street Journal, The Guardian, The Times of London, The Economist, The Daily Telegraph, Technology Review, and others. His work with the Undiagnosed Diseases Network was covered by National Public Radio[22] and The New York Times.[23]
