One injustice that is central to my research is the increased prevalence of low-quality medicines and contaminated food/water/cosmetics in less developed countries. For the past twelve years, I have dedicated my scholarly efforts toward the development of paper-based analytical devices (PADs) for the rapid and reliable screening of medicines and food/water. My team of chemistry researchers at Saint Mary’s College has worked closely with Dr. Basant Giri’s team of student researchers at Kathmandu Institute of Applied Sciences (KIAS) to collect and analyze select medicines from different regions of Nepal. As a Fulbright Global Scholar, I am expanding the PADs technology for the screening of low-quality ayurvedic medicines in Nepal and assessing the lead content of various cosmetics collected in Nepal, Ghana, and Uganda.
