Dr. Nicholas Ashton earned his PhD in Old Age Psychiatry from King’s College London under the mentorship of Sir Professor Simon Lovestone, where he embarked on a decade-long quest to develop an accurate blood test for Alzheimer’s disease. In 2018, he joined the world-renowned laboratory of Dr. Henrik Zetterberg at the University of Gothenburg, Sweden, leading a team in the pioneering development and implementation of Alzheimer’s disease blood tests—particularly phosphorylated tau (p-tau)—in research settings. These tests now form the foundation of widely used clinical diagnostics and are currently under evaluation by the FDA.

Notably, Dr. Ashton was the lead investigator for the first commercially available immunoassay for p-tau217, which became the most downloaded research article in the field of dementia in 2024. Over the past five years, he has published more than 400 original research articles and is among the youngest scientists listed on Clarivate’s “Highly Cited Researchers” list (2023, 2024). He is widely recognized for his leadership and international collaborations, playing a pivotal role in advancing biomarker research. His contributions have earned him several prestigious awards, including the Queen of Sweden Research Prize (2023), the Viola Bergqvist Award for Mentorship (2024), and the European Researcher Prize in Dementia (2025).

In his new role as Senior Director of the Fluid Biomarker Laboratory at Banner Sun Health Research Institute (BSHRI), Dr. Ashton continues to refine and evaluate blood tests for Alzheimer’s disease, particularly assessing their role in the prevention of the disease. His laboratory serves as a critical resource for research institutions and biotech companies across Arizona, the U.S., and internationally. His latest research focuses on developing at-home tests for Alzheimer’s disease risk assessment and expanding similar biomarker-based diagnostics for other types of dementia (e.g., Lewy body disease) which is currently an unmet need.
