Mary Luckey is Professor Emerita in the Department of Chemistry and Biochemistry at San Francisco State University. She earned her PhD in Biochemistry at the University of California, Berkeley with the first identification of an iron transport protein in the bacterial outer membrane. Her postdoctoral work demonstrated the specificity of the E. coli maltoporin in proteoliposomes. While continuing research on maltoporin structure and function, she has taught biochemistry for over 25 years, including the graduate-level membrane biochemistry course that provided the impetus for this book.
