Activism Nagarajan has worked with a wide range of various international and grassroots organisations and previously lived and worked in Nigeria. Her work has spanned various sectors, and she has contributed to new areas of analysis by drawing connections between previously unconnected areas of work. In the report "Shoring Up Stability: Addressing Climate & Fragility Risks in the
Lake Chad Region", Nagarajan was part of the team who wrote the first ever climate and fragility assessment of a specific region. and inter-communal conflict between farmers and pastoralists, explored in a report for
Mercy Corps, among other topics. She has also worked for human rights and peace in northern Nigeria and the Boko Haram conflict since 2013, including training soldiers on human rights,
international humanitarian law and how to mitigate civilian harm in operations; and looking at reintegration of people formerly associated with armed groups after their exit. In addition to her research and activism in West Africa, Nagarajan has also been involved in feminist movements in the UK, and was previously on the management committee of
Southall Black Sisters. Her approach has been described as having a "a deep commitment to centering the voices of those often left unheard."
Writing Nagarajan has written for media outlets such as
The Guardian,
This is Africa,
openDemocracy and
the New Internationalist. In 2018, together with Azeenarh Mohammed and Rafeeat Aliyu, Nagarajan co-edited a collection of narratives from queer Nigerian women, called
She Called Me Woman. The book has been described as "a space in which transgressive stories of love, lust and longing can be heard on their own terms." Feminist scholar
Sara Ahmed noted in the blurb "this book will change lives by giving voice to experiences that are too often forgotten or erased." The book was published within a political context of state-led crackdowns on homosexuality in Nigeria, and as a result, the book "also works as a strong rebuttal to the
Same-Sex Marriage Prohibition Act 2013." In 2025, Nagarajan published
The World Was in Our Hands: Voices from the Boko Haram Conflict: a collection of accounts of people living through the Boko Haram conflict, from vastly different perspectives. As part of the
research and writing for
The World Was In Our Hands, she spent up to five hours with individual people as they narrated the stories of their lives. Part of the motivation behind the book was her desire to shine a light on the diversity of people's experiences that were often different to mainstream narratives shared in the media and through politics. The book was described by journalist and author
Angela Saini as a "remarkable chronical of the people who have lived through some of the most harrowing events in recent history, often spoken about, yet rarely listened to." == Publications ==
