Girish Sahni is a biology 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 Girish Sahni rather than just read about it. In short: Girish Sahni (2 March 1956 – 19 August 2024) was an Indian biotechnologist and science administrator. He served as the Director-General of the Council of Scientific and Industrial Research (CSIR) and Secretary to the Department of Scientific and Industrial Research (DSIR), Government of India, from 2015 to 2018.

Key takeaways

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

Reference excerpt

Girish Sahni (2 March 1956 – 19 August 2024) was an Indian biotechnologist and science administrator. He served as the Director-General of the Council of Scientific and Industrial Research (CSIR) and Secretary to the Department of Scientific and Industrial Research (DSIR), Government of India, from 2015 to 2018. Prior to this, he was Director of the CSIR-Institute of Microbial Technology (IMTECH), Chandigarh, from 2005 to 2015. In 2014, he received the Vigyan Ratna Award, India's highest national recognition for scientists, awarded under the Rashtriya Vigyan Puraskar (RVP) for lifetime achievements and profound contributions to any field of science and technology by the Government of India

Early life and education Girish Sahni was born on 2 March 1956 in India. He obtained his PhD from the Indian Institute of Science, Bengaluru. He later pursued post-doctoral research at the University of California, Santa Barbara, Rockefeller University, New York, and the Albert Einstein College of Medicine, New York.

Career Sahni joined the CSIR-Institute of Microbial Technology (IMTECH) in 1991. Over the years, he rose through the ranks and became Director of the institute in 2005. In 2015, Sahni was appointed Director-General of the Council of Scientific and Industrial Research (CSIR), one of the largest publicly funded research and development organizations in the world. Concurrently, he served as Secretary to the Department of Scientific and Industrial Research (DSIR). After completing his tenure in 2018, he continued to mentor young scientists and remained engaged with the scientific community.

Research and contributions Sahni's research focused primarily on cardiovascular biology and biotechnology. He is best known for his role in the development of recombinant streptokinase, India's first indigenous clot-dissolving drug used in the treatment of heart attacks.

Death Girish Sahni died on 19 August 2024 at the age of 68. His death was widely mourned by the scientific and academic communities in India.

Worked examples

Example 1 — a first encounter with Girish Sahni

Start with the simplest possible case. Write down what Girish Sahni 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 Girish Sahni 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 Girish Sahni 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 Girish Sahni

In research: Girish Sahni 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 Girish Sahni 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: Girish Sahni is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1956 births, 2024 deaths, Indian Institute of Science alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Girish Sahni 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.
