Reference excerpt

Roshan Sethi is a Canadian physician and film director, currently working in the United States.

Background Originally from Calgary, Alberta, Sethi worked as a radiation oncologist at Brigham and Women's Hospital in Boston, Massachusetts, before taking some time off to write for the medical drama series Code Black. He was a co-creator of the American medical drama series The Resident, which ran for six seasons, 2018–2023. He still practices medicine part-time.

Film career He released his debut film 7 Days in 2021. The romantic comedy film was based in part on his experiences as a medical professional in the early days of the COVID-19 pandemic, in 2021. The film won the 2022 Independent Spirit Award for Best First Feature. In 2022, he was a co-writer of the screenplay for Call Jane. He directed the films World's Best in 2023, and A Nice Indian Boy in 2024. "World's Best" was nominated for a Children's and Family Emmy in 2025. In 2026, Sethi wrote and directed The Surgeon starring Michelle Yeoh which will have its world premiere at the 2026 Toronto International Film Festival.

Personal life Sethi came out as gay at age 30. He is married to actor Karan Soni, who has been a credited cowriter and/or cast member in all of Sethi's films to date.

Worked examples

Example 1 — a first encounter with Roshan Sethi

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

In research: Roshan Sethi appears in science 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 Roshan Sethi 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: Roshan Sethi is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century Canadian LGBTQ people, 21st-century Canadian male writers, 21st-century Canadian medical doctors, so understanding it makes those chapters shorter.
In everyday life: Look for Roshan Sethi 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.
