Reference excerpt

Kang Zhang (Chinese: 张康) is a Chinese-American ophthalmologist specializing in ophthalmic genetics and aging processes in the eye. He is currently a professor of the Faculty of Medicine at Macau University of Science and Technology. He was previously a professor of ophthalmology and the founding director of the Institute for Genomic Medicine at the University of California, San Diego. In 2017, the U.S. Food and Drug Administration issued a notice related to his research oversight, and he later left UC San Diego in 2019. He subsequently moved to China and continues his research, which includes work on lanosterol. stem cell research (particularly limbal stem cells), gene editing, and artificial intelligence.

Education Born in Chengdu, Sichuan Province, China, Zhang obtained his B.S. in Biochemistry from Sichuan University in Chengdu, China in 1984. In 1991, Zhang graduated with a Ph.D. in Genetics from Harvard University. Subsequently, Zhang obtained his M.D. from a Harvard University Medical School and Massachusetts Institute of Technology Joint M.D. Program with magna cum laude honors in 1995.

Career After completing an ophthalmology residency at the Wilmer Eye Institute at Johns Hopkins University, Zhang became assistant staff at the Cole Eye Institute at the Cleveland Clinic Foundation. Zhang completed a retina fellowship at the University of Utah, and afterwards became an assistant professor at the University of Utah from 2002 to 2006. In 2012, following an anonymous complaint, the UCSD Institutional Review Board (IRB) suspended enrollment in Zhang's research studies. After an internal review, the research was permitted to resume. In 2013, Zhang, along with Trey Ideker, identified that the molecular aging clock could be measured by blood and tissues, and made use of epigenetic markers. In 2014, Zhang, along with Yizhi Liu and Xiangdong Fu, investigated mechanisms and developed a new method of limbal stem cell repair and regeneration. Zhang has also pioneered the usage of artificial intelligence in diagnosing eye diseases. In 2015, Zhang discovered that lanosterol can be used in eyedrop form to help prevent cataracts. In 2017, the FDA issued a warning letter to Zhang citing violations in his oversight of human research studies and restricted him from serving as a principal investigator on such studies. The letter referenced issues dating back to 2012. Subsequently, a UCSD internal audit identified what it described as shortcomings in Zhang's research practices. In 2019, a clinical trial in China involving Zhang prompted a letter from international doctors questioning its ethics and methodology. Around the same time, media reports noted his undisclosed ties to a Chinese ophthalmology company. UCSD placed Zhang on administrative leave; he later resigned. The university investigated his connections to Chinese entities. Zhang's lawyer said the leave and investigation stemmed from the 2017 FDA warning, not ties to China. Zhang had been affiliated with the Thousand Talents Plan, a Chinese recruitment program the FBI has scrutinized for counterintelligence risks. After leaving UCSD, he joined the Faculty of Medicine at Macau University of Science and Technology. In 2019, Zhang was recruited to Macau University of Science and Technology to establish Macau's first medical school, where he became Vice-Dean for Research and Chair Professor in the Faculty of Medicine, as well as Director of the Macau Institute for AI in Medicine. In 2021, Zhang and colleagues published a study in Nature Biomedical Engineering demonstrating that deep‑learning models could detect chronic kidney disease and type 2 diabetes from retinal fundus images, with potential applications in resource‑limited settings. In 2023, he was profiled in Cell Reports Medicine, where he described his work on multi‑modal artificial intelligence and was listed as a Clarivate Highly Cited Researcher in Cross‑Field for 2019–2022. He was appointed Vice President of Macau University of Science and Technology in 2024. In 2026, he co‑authored a paper in npj Digital Medicine describing an AI model for personalized prediction of myopia progression in children. Zhang and colleagues proposed and implemented MetaGP, a generative medical foundation model that integrates large-scale electronic health records with multimodal medical imaging, in 2025. Zhang, together with Jia Qu, also developed MINIM, a general-purpose large-scale generative synthetic medical image model, in 2025. In 2026, Zhang, together with Shanshan Wang, developed AFLoc, a pathology vision–language model capable of lesion localization.

Worked examples

Example 1 — a first encounter with Kang Zhang

Start with the simplest possible case. Write down what Kang Zhang 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 Kang Zhang 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 Kang Zhang 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 Kang Zhang

In research: Kang Zhang 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 Kang Zhang 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: Kang Zhang is common in secondary-school and first-year university syllabi. It links to neighbouring topics American medical academics, American ophthalmologists, Chinese ophthalmologists, so understanding it makes those chapters shorter.
In everyday life: Look for Kang Zhang 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.
