Muneera Rasheed
Ms. Muneera Rasheed is a researcher, academic, and practitioner based in Pakistan. Her work focuses on early childhood development and spans projects across South Asia and East Africa. Trained as a clinical psychologist, her work is grounded in direct engagement with children and families, bringing an understanding of relational care to her research.
In her work, she explores how children’s development unfolds within complex social, cultural, and structural realities. Her work critically engages with dominant global health and education paradigms, interrogating how these systems see—or fail to see—the child embedded within family, community, and culture. Writing from and for the Global South, Ms. Rasheed contributes to conversations on decolonising knowledge, research, and intervention design, advocating for approaches that move beyond technocratic and one-size-fits-all solutions. Through her research, she foregrounds context, lived experience, and relational care as central to building more just and responsive systems for children and families.
