Howitt, Susan - The Australian National University

个人简介

Professor Susan Howitt completed her PhD at ANU, working on the genetics of symbiotic nitrogen-fixing bacteria. She then changed fields, moving to the John Curtin School of Medical Research to work first on the E. coli ATP synthase and later becoming involved in a project on the GABAA receptor. Both projects used genetic approaches to address the structure and function of these proteins and this research led to her current interest in another class of membrane proteins, nutrient transporters. In 1997 Susan was appointed to a lecturing position. This has led to an increasing interest in learning and teaching and she has completed a Master in Higher Education. Her current research interests are in the area of student learning, in particular relating to conceptual learning and learning about research.

研究领域

My science research interest is in how transporters function and we aim to understand their molecular mechanisms. We are using heterologous expression systems to characterize transporters and mutant variants that have been generated by site-directed mutagenesis or random methods. This allows us to test hypotheses about which regions of the transporter are important for function. Our current focus is on sulphate transporters from plants and bicarbonate transporters from cyanobacteria.
