Anna Seelig-Löffler is a Swiss biophysical chemist who worked at the Biozentrum University of Basel, Switzerland.

[1] Her areas of expertise include the structural and functional analysis of membranes and their lipid and protein components.

[2] More recently her work focused on ATP Binding Cassette (ABC)[3] transporters, such as P-glycoprotein, which prevent drug uptake across cell membranes and cause multidrug resistance.

[4] Based on these findings she developed a model to predict drug uptake across biological membranes.
