Feifei Xia developed and refined course materials for the compbiozurich/UZH-BIO392 repository, focusing on bioinformatics education. She created and organized Day 1 presentation slides and structured Day 9 Sequence Analysis Practical resources, including a detailed README with objectives and instructions for VCF, IGV, and VEP workflows. Her work emphasized clear documentation and version-controlled content management using Markdown, ensuring that materials were both accessible and maintainable. By cleaning up superseded files and packaging resources for student use, Feifei improved repository hygiene and streamlined the content lifecycle, demonstrating depth in data interpretation, sequence analysis, and practical bioinformatics workflow curation.
