UNICEF/Bihar education Project Council, Government Of Bihar, India
I developed strategies to institute the SSHE program in more than 5,000 schools in Bihar, India in coordination with state and district agencies for sanitation, health, engineering, and public relations as well as UNICEF and several NGOs. I managed a $200,000 (USD) budget to facilitate construction of more than 1,000 toilets in schools. I also established data collection methods for information on education, sanitation, health, and hygiene of students and instructors. Additionally, I built an online data reporting and monitoring system to support ongoing implementations and improvements, including updates to the online portal of India’s Department of Drinking Water and Sanitation. I designed and prepared reports for review meetings and updates as well as program evaluation and impact assessments. I also created training modules and materials for teachers and students and shared best practices with local communities.
I collaborated on UNICEF’s flagship project “Assessing and Mapping Groundwater Arsenic Contamination of Bihar, India,” leading a team of 16 in testing public hand pumps for contamination in more than 50 villages throughout Bihar, India. I developed the project proposal under the supervision of the Principal Investigator. I also created a state-level data repository, established laboratories at the district level, and trained engineers. Additionally, I devised quantitative and qualitative data collection formats and household surveys. I created and standardized analytical methods and chemical inventory. I also marked tested sources, prepared field maps, and educated local communities on arsenic contamination and safety.
