ABOUT ME

“Research is not only about discovering knowledge, but about honoring the voices and experiences that shape our world.”

I am Sithuni Mimasha, a PhD student in Geospatial and Environmental Analysis in the Department of Geography at Virginia Tech, USA. My research focuses on Indigenous Peoples, with an emphasis on understanding their landscapes, knowledge systems, and lived experiences through geospatial and environmental approaches. Through my work, I aim to contribute to research that is ethical, inclusive, and grounded in respect for Indigenous communities.
