Dr. Ming-Mei Chang is a plant molecular biologist whose research encompasses DNA cloning, gene expression, and genetic manipulation, with applications in agriculture, medicine, and authentication (DNA taggants). She has authored over 20 peer-reviewed papers in agriculture and medicine, with an emphasis on plant disease resistance for crop protection. She is a recipient of the research award from the New York State Wine and Grape Foundation for her significant contribution to viticulture research in the New York wine and grape industry. In addition to research, she had years of teaching experience in molecular and cell biology, as well as in associated lab courses, at SUNY Geneseo. She is committed to designing and teaching lab courses that provide research experiences for undergraduates and make the content accessible to all. Throughout her teaching career, she has developed undergraduate laboratory exercises that employ techniques widely used in molecular biology research and published them in the peer-reviewed journal Biochemistry and Molecular Biology Education. This lab book, Molecular Techniques, is the culmination of her extensive experience in teaching, particularly labs, and mentoring undergraduate research. It offers students a resource that integrates practical and basic lab techniques into their learning experience. Outside the classroom and lab, Ming-Mei likes traveling, hiking, kayaking, swimming, and practicing Chinese calligraphy.
