She is a professor of mathematics and Canada Research Chair at University of British Columbia, Canada.

Key takeaways

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

Reference excerpt

Sujatha Ramdorai (born 1962) is an algebraic number theorist known for her work on Iwasawa theory. She is a professor of mathematics and Canada Research Chair at University of British Columbia, Canada. She was previously a professor at Tata Institute of Fundamental Research.

Education She completed her B.Sc. in 1982 at St. Joseph's college, Bangalore and then got her M.Sc. through correspondence from Annamalai University in 1985. After that she went for PhD at Tata Institute of Fundamental Research and was awarded her PhD under supervision of Raman Parimala in 1992. Her dissertation was "Witt Groups of Real Surfaces and Real Geometry".

Career Dr. Ramdorai initially worked in the areas of algebraic theory of quadratic forms and arithmetic geometry of elliptic curves. Together with Coates, Fukaya, Kato, and Venjakob she formulated a non-commutative version of the main conjecture of Iwasawa theory, on which much of the foundation of this important subject is based. Iwasawa theory has its origins in the work of a great Japanese mathematician, Kenkichi Iwasawa. She holds an adjunct professorship position at Indian Institute of Science Education and Research, Pune. Working with her husband Srinivasan Ramdorai and Indian mathematics writer V.S. Sastry, Sujatha Ramdorai conceived of and partially funded the Ramanujan Math Park in Chittoor, Andhra Pradesh, which was inaugurated at the end of 2017. The park is dedicated to mathematics education and honors the great Indian mathematician Srinivasa Ramanujan (1887-1920). She is a member of the Scientific Committee of several international research agencies such as the Indo-French Centre for Promotion of Advanced Research, Banff International Research Station, International Centre for Pure and Applied Mathematics. She was a member of the National Knowledge Commission from 2007 to 2009. She is at present a member of the Prime Minister's Scientific Advisory Council from 2009 onwards and also a member of the National Innovation Council. She is also on the advisory board of Gonit Sora.

Awards and honors Ramdorai became the first Indian to win the prestigious ICTP Ramanujan Prize in 2006. She was also awarded the Shanti Swarup Bhatnagar Award, the highest honour in scientific fields by the Indian Government in 2004. She is also the recipient of the 2020 Krieger–Nelson Prize for her exceptional contributions to mathematics research. She has been bestowed with Padma Shri award by the Government of India for 2023 in the field of science and engineering.

Worked examples

Example 1 — a first encounter with Sujatha Ramdorai

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

In research: Sujatha Ramdorai appears in mathematics 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 Sujatha Ramdorai 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: Sujatha Ramdorai is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1962 births, 20th-century Indian mathematicians, 20th-century Indian women scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Sujatha Ramdorai 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.
