Reference excerpt

Jyotsna Dhawan is an Indian Cell and Developmental Biologist, Emeritus Scientist at Centre for Cellular and Molecular Biology and Visiting Professor, Institute for Stem Cell Science and Regenerative Medicine (inStem). Dhawan's research has focused on adult stem cell function and skeletal muscle regeneration. Dhawan is the current (2019-2021) President of the Indian Society for Cell Biology and the Indian Society of Developmental Biologists (2017–2020). Dhawan was elected as a fellow to the Indian National Science Academy in 2019.

Early life and education Dhawan's father Satish Dhawan was a faculty at the Indian Institute of Science and Dhawan's mother Nalini, was a cytogeneticist. She completed her master's in botany from Delhi University in 1983. She contemplated quitting her master's degree however, a summer internship in yeast genetics at the Tata Institute of Fundamental Research, convinced her to pursue a PhD. She completed her PhD from Boston University in 1991. She completed her postdoctoral training at Stanford University studying muscle stem cells and gene therapy in 1995.

Career Dhawan joined Centre for Cellular and Molecular Biology as faculty in 1996 and started her lab studying the biology of muscle stem cells and muscle repair. From 2009–2014, she helped set up the Institute for Stem Cell Science and Regenerative Medicine (inStem) in Bangalore and served as Senior Professor and Dean. In 2014, she returned to Centre for Cellular and Molecular Biology and retained ties to InStem as a visiting professor and member of the advisory board. Dhawan has been an active advocate for establishing India as a leader in biomedical research. She serves as the Scientist In Charge of Centre for Cellular and Molecular Biology’s iHub, an innovation space with an incubation center for biomedical startups and has served on several scientific review committees, scientific task forces and advisory boards at the national and institutional level. She has also been a part on the editorial board of Physiological Genomics, BBRC and Frontiers in Cell and Developmental Biology.

Worked examples

Example 1 — a first encounter with Jyotsna Dhawan

Start with the simplest possible case. Write down what Jyotsna Dhawan 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 Jyotsna Dhawan 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 Jyotsna Dhawan 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 Jyotsna Dhawan

In research: Jyotsna Dhawan 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 Jyotsna Dhawan 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: Jyotsna Dhawan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century Indian scientists, 20th-century Indian women scientists, 21st-century Indian scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Jyotsna Dhawan 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.
