I worked as a Research Investigator with icddr,b at Bangladesh. Last ten years, I have been contributing in the field of child health and nutrition, communicable diseases, water sanitation and hygiene, outbreak investigation, and infection control. I did my graduation in Anthropology and obtained MPH in Epidemiology. I worked with the Children's Investment Fund Foundation, UK (CIFF), USAID, Centers for Disease Control and Prevention (CDC), Save the Children, UNICEF, Plan International and University of Sussex. During these years, I was a key team member on 12 research projects with icddr,b, and participated large-scale evaluation studies. Additionally, I was actively present to prepare manuscripts, submit to peer-reviewed journal, and response to feedback.
