Lijuan Yuan

Lijuan Yuan is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lijuan Yuan rather than just read about it. In short: Lijuan Yuan (袁丽娟) is a Chinese-American virologist and academic researcher. She is a Professor of Virology in the Department of Biomedical Sciences and Pathobiology at the Virginia–Maryland College of Veterinary Medicine, Virginia Polytechnic Institute and State University (Virginia Tech).

Key takeaways

Lijuan Yuan belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Lijuan Yuan to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Lijuan Yuan from memory before moving on to harder problems.

Reference excerpt

Lijuan Yuan (袁丽娟) is a Chinese-American virologist and academic researcher. She is a Professor of Virology in the Department of Biomedical Sciences and Pathobiology at the Virginia–Maryland College of Veterinary Medicine, Virginia Polytechnic Institute and State University (Virginia Tech). She also holds appointment as Professor of Virology with the Faculty of Health Sciences for the Translational Biology, Medicine, and Health (TBMH) Program at Virginia Tech. She is known for her contributions to mucosal immunology, human enteric viral disease research, and preclinical evaluation of human rotavirus and norovirus vaccines using gnotobiotic pig models.

Education Yuan received her Ph.D. in immunology and virology in 2000 from Ohio Agricultural Research and Development Center, The Ohio State University, under Linda J. Saif. She completed an M.S. in Beijing and diplomas from Peking University and a Beijing health school.

Career Yuan worked at The Ohio State University from 2002 to 2007, before joining Virginia Tech in 2007, where she was promoted to Associate Professor in 2013 and Professor of Virology in 2019, with a concurrent appointment in its Translational Biology, Medicine, and Health program since 2014.

Research Yuan's research activities include host–pathogen interactions in enteric viruses, examining viral infectivity, pathogenesis, and immune responses, and developing intervention strategies including vaccines, prophylactics, therapeutics, probiotics, and prebiotics. Her laboratory focuses on the use of gnotobiotic pig models to study human rotavirus and norovirus infections, evaluating vaccine immunogenicity, protective efficacy, and novel immunization routes.

Worked examples

Example 1 — a first encounter with Lijuan Yuan

Start with the simplest possible case. Write down what Lijuan Yuan claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Lijuan Yuan 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 Lijuan Yuan 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 Lijuan Yuan

In research: Lijuan Yuan appears in astronomy 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 Lijuan Yuan 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: Lijuan Yuan is common in secondary-school and first-year university syllabi. It links to neighbouring topics American virologists, American women scientists, Chinese emigrants to the United States, so understanding it makes those chapters shorter.
In everyday life: Look for Lijuan Yuan 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.
