Reference excerpt

Earl Ray Dorsey is an American neurologist who leads the Center for the Brain & the Environment at the Atria Health and Research Institute. Previously, he directed the Center for Health + Technology at the University of Rochester, chaired the international Huntington Study Group, and led the movement disorder division and neurology telemedicine at Johns Hopkins Medicine. Dorsey has studied and published results from programs related to movement disorders, including Huntington's disease and Parkinson's disease. In 2015, the White House named him as one of eight "Champions of change in the fight against Parkinson's disease".

Education Dorsey earned his Bachelor of Science degree in biological sciences at Stanford University. He subsequently received Doctor of Medicine and Master of Business Administration degrees from the University of Pennsylvania's School of Medicine and the Wharton School. Dorsey completed his neurology residency at the Hospital of the University of Pennsylvania and a fellowship in movement disorders and experimental therapeutics at the University of Rochester Medical Center.

Career In 2007, Dorsey and fellow neurologist Kevin Biglan started a telehealth program for Parkinson's patients in nursing homes. The duo published results from the program and continued to collaborate when Dorsey was at Johns Hopkins Medicine from 2010 to 2013. Dorsey was the director of the movement disorder division and neurology telemedicine at Johns Hopkins Hospital. Dorsey returned to URMC in 2013 and became the director of the Center for Health + Technology in 2014. There Dorsey led a smartphone application research study called mPower. He and Suchi Saria were among co-authors of a research paper for the study published by JAMA Neurology, which was funded by the National Institute of Neurological Disorders and Stroke and The Michael J. Fox Foundation. Dorsey also helped lead URMC's Parkinson Disease Care New York, a statewide telemedicine program for people with Parkinson's disease. In 2015, the White House named Dorsey as one of eight "Champions of change in the fight against Parkinson's disease". At Rochester, Dorsey holds the David M. Levy Professorship of Neurology. From 2014 to 2018, Dorsey was the chair of the Huntington Study Group, an organization that seeks to find new treatments for those with Huntington's disease. He co-wrote the books Ending Parkinson's Disease: A Prescription for Action (2020) and The Parkinson's Plan: A New Path to Prevention and Treatment (2025), which reached The New York Times Best Seller list in September 2025, and which Publishers Weekly describes as a "prescriptive guide" of the disease. Dorsey and co-author Michael S. Okun received the 2022 Tom Isaacs Award from The Cure Parkinson's Trust and the Van Andel Institute for their work related to the disease. Combined, as of 2025, the two have published approximately 1,000 papers and treated 10,000 people with Parkinson's. In Ending Parkinson's, Dorsey, Okun, and their co-authors called Parkinson's "a man-made pandemic". Dorsey's research has been published in medical and economic journals, and featured in media outlets such as NPR, The New York Times, and The Wall Street Journal.

Worked examples

Example 1 — a first encounter with Ray Dorsey

Start with the simplest possible case. Write down what Ray Dorsey claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ray Dorsey before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ray Dorsey ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ray Dorsey

In research: Ray Dorsey appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ray Dorsey in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ray Dorsey is common in secondary-school and first-year university syllabi. It links to neighbouring topics American neurologists, Johns Hopkins Hospital physicians, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Ray Dorsey outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
