Indian Women, Transgender and Non-binary Persons in Science 2022-23

The fifth edition of TLoS's yearly desktop calendar has been launched. It features 48 Indian women, transgender and non-binary persons working in various fields of science.
By | Published on Feb 11, 2022

Since 2018, we have found our annual tradition: production of our Indian women, transgender and non-binary persons in science calendar. The initial versions of the calendar were geared towards highlighting contributions of individual women scientists, this changed in 2020. We have realised that the “women in science” framing is too narrow to encapsulate experiences of people from marginalised genders and have, since 2021, broadened the scope of the calendar to include transgender and non-binary persons.

Moreover, we have also moved away from highlighting contributions of individual people on each page to a more thematic representation of the Indian science ecosystem. The 2021 calendar highlighted various roles — from administrators to principal investigators to science journalists, technicians and more — that keep Indian science running.

This year, we tried something different. We identified several concepts as our broad themes for each page. The page for each concept — for example, neurodivergence, the pandemic or model organisms — showcases the contributions of several people working in the field. We’ve tried our best to curate a diverse list of ~50 Indian women, transgender and non-binary persons, many of who were also featured in our #365IndianWomeninScience initiative.

Some of the people featured in this calendar have fought long-drawn public health battles, some have helped us understand how we create and process music, some have charted out the path for us to live harmoniously with other beings on the planet, some have helped us understand lacks in science and science practice — the list is really endless!

What’s more? We are also offering a calendar/planner that you can use to plan your days on!

As we launch our calendar today, 11 February 2022, to mark the International Day of Women and Girls in Science, we hope you will support our endeavour by ordering a copy for yourself (links to order below). By getting a calendar or a calendar/planner you will supporting activities on for the next year that aim to investigate the gaps in Indian science, host a sociocultural dialogue with the Indian science community, and promote diversity and equity in Indian academia. We suggest you order ASAP, since we only have a few copies left. Thanks for the support!
