Reference excerpt

Haifan Lin (Chinese: 林海帆; pinyin: Lín Hǎifān) is a Chinese-born American stem cell biologist. He is the Eugene Higgins Chair Professor of Cell Biology at Yale University and the founding Director of the Yale Stem Cell Center. He previously founded and directed the Stem Cell Research Program at Duke University. Recognized for his significant contributions to stem cell research, he was elected to the US National Academy of Sciences and American Academy of Arts and Sciences in 2018, the Chinese Academy of Sciences as a Foreign Member in 2021, and the US National Academy of Medicine in 2024.

Biography Lin was born in Dongtou, Wenzhou, Zhejiang, China. In 1982, he graduated from Fudan University in Shanghai with a bachelor's degree in biochemistry. He moved to the United States to pursue graduate studies at Cornell University and earned his PhD in 1990 in genetics and development. He subsequently worked as a Jane Coffin Childs Fellow for Medical Research at the Carnegie Institution for Science. In 1994, he became a faculty member of Duke University School of Medicine, and later established the Stem Cell Research Program in 2005. In 2006, Lin moved to Yale University, where he founded the Yale Stem Cell Center and served as its director. He is also the Eugene Higgins Chair Professor of Cell Biology, Professor of Genetics, of Obstetrics, Gynecology, & Reproductive Sciences, and of Dermatology at Yale School of Medicine. From 2014 to 2022, Lin served concurrently as the adjunct founding dean of ShanghaiTech University's School of Life Science and Technology in China, while retaining his positions at Yale. Lin's work is focused on the self-renewing mechanism of stem cells, especially the small-RNA-mediated gene regulation mechanism. His research uses Drosophila germline stem cells, mouse germline stem cells, and mouse embryonic stem cells as models. He also studies germline development and stem cell-related cancers. Lin is recognized for his contributions to stem cell and developmental biology research, especially for his discoveries of the Piwi/Argonaute (AGO) gene family and the Piwi-interacting RNAs (piRNAs), and for contributing to the demonstration of asymmetric stem cell division and to the proof of the stem cell niche theory. The journal Science named the discovery of piRNAs as one of the ten most important breakthroughs in 2006. In recent years, he demonstrated the crucial roles of the Piwi-piRNA pathway in epigenetic programming and post-transcriptional regulation of mRNA and lncRNA (see Select Bibliography). Lin has played numerous leadership roles globally in the scientific community. He is President (2022-2023) of the International Society for Stem Cell Research (ISSCR) and has served as Director (2009-2019, 2020–present), Treasurer (2013-2016), Executive Committee Member, Vice President (2020-2021), and President-Elect (2021-2022) of ISSCR; Chair of the Finance Committee (2013-2016); Chair the Publications Committee (2009-2012), and Chair the Annual Meeting Program Committee (2010-2011) of the ISSCR. He led the establishment of ISSCR's official journal, Stem Cell Reports (2010-2012). Lin has also served on the Medical Advisory Board of New York Stem Cell Foundation (2009–present), the US National Institutes of Health (NIH) Director's Pioneer Award Selection Committee (2009), the NIH study sections (1998-2005, 2007, 2012, 2014, 2019–2020), the Board of Directors of the Society of Chinese Biological Investigators, USA (2002-2008), the Council of the Society of Chinese Bioscientists in America (2008-2011), the Advisory Council of RIKEN Center for Developmental Biology, Japan (2007-2015), the Scientific Advisory Board of the Jane Coffin Childs Memorial Fund for Medical Research (2011-2015), National Key Stem Cell Research Advisory Committee, Chinese Ministry of Science and Technology (2011-2014), the Council of Shantou University (2010-2015), and the Council of Connecticut Academy of Science and Engineering (2013-2016). He was a co-founder and Core Member of the Connecticut State Government Life Sciences Advisory Group (2011-2012) and served on the advisory board of Connecticut Innovation Bioscience Fund (2017-2020).

Worked examples

Example 1 — a first encounter with Haifan Lin

Start with the simplest possible case. Write down what Haifan Lin 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 Haifan Lin 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 Haifan Lin 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 Haifan Lin

In research: Haifan Lin 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 Haifan Lin 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: Haifan Lin is common in secondary-school and first-year university syllabi. It links to neighbouring topics American geneticists, American molecular biologists, Biologists from Zhejiang, so understanding it makes those chapters shorter.
In everyday life: Look for Haifan Lin 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.
