Ms. Yvonne Tusiimire has marked an important step in her academic journey after successfully defending her PhD at Makerere University. Her research, “3D Electrospun PLLA Nanofibrous Membranes Coated with Regenerated Silk Fibroin and Silver Nitrate for Burn Wounds,” contributes to ongoing efforts to improve materials used in burn care.

The study focused on developing a biomimetic scaffold designed to support better healing outcomes. In the course of her work, she developed and refined a 3D electrospun PLLA membrane coated with regenerated silk fibroin and silver nitrate. She also examined how plasma finishing and biodegradation affect the material, assessed cell viability and cytotoxicity, and evaluated its antibacterial properties. These combined investigations provide useful insight into how such materials may perform in practical medical settings.

Her Viva Voce took place on April 22, 2026, at the College of Engineering, Design, Art and Technology, with both in-person and online participation. The session began with detailed feedback from Dr. Edwin Kamalha, who raised key structural and technical points during an hour-long discussion. This was followed by further engagement with a panel of six examiners, who explored different aspects of the study, including methodology and interpretation of results.

Over the course of the four-hour examination, Ms. Tusiimire responded to questions with clarity and composure, demonstrating a solid understanding of her research area.

Her successful defense reflects sustained effort and careful scholarship, and adds to the body of research addressing challenges in wound management through advances in science and engineering.
