Sameer Ansari completed a 12-month internship at P&G in Brussels focused on improving polymer interdiffusion in soluble unit dose pouches. He quickly connected with experts to understand polymer welding mechanisms and designed a test plan. Sameer perfected a tackiness test method to characterize welding and modeled the impact of process variables. By the end of the internship, he delivered an improved, validated method and recommendations. Sameer demonstrated strong scientific curiosity, independence, and excellent project execution skills. His work has been implemented across P&G sites to better understand pouch sealing and answer questions more quickly.
