Haibo Yu joined the University of Wollongong as a Lecturer in the School of Chemistry in July 2010. He completed his undergraduate degree at the University of Science and Technology of China (USTC) and his Ph.D. at the Swiss Federal Institute of Technology (ETH) Zürich under the supervision of Professor Wilfred F. van Gunsteren. He then conducted post-doctoral research at the University of Wisconsin-Madison with Professor Qiang Cui and the University of Chicago with Professor Benoît Roux in the United States. In November 2011, he was awarded an Australian Research Council Future Fellowship. His research interests focus on the development and application of theoretical and computational models to understand the structure-dynamics-function relationship in complex biomolecular systems.



Ian Ratheal studied biology at the University of Texas Tech. He worked on Na/K ATPase research with Professor Pablo Artigas during his undergraduate education and continued after graduation as a research technician. Now he is enjoying medical school at the Texas Tech Health Science Center.



Pablo Artigas studied biology and biophysics at the University of the Republic, in Montevideo, Uruguay. He obtained a M.S. in 1999 (studying cardiac Ca channels with Professors G. Pizarro and G. Brum), and a Ph.D. in 2002 (his thesis focused on Na/K pump mechanism, with D. C. Gadsby as advisor). After his post-doctoral research at Rockefeller University, he joined the Texas Tech University Health Sciences Center in 2007 and has continued his investigations into the relationship between the Na/K pump structure and its mechanism, with particular emphasis on intramolecular interactions and the mechanisms of ion binding and ion selectivity.



Benoît Roux first studied physics and biophysics at the University of Montréal. In 1990, he obtained a Ph.D. in biophysics from Harvard University under the direction of Martin Karplus. In the last decade, he has held positions at the University of Montréal and the Weill Medical College of Cornell University. Since 2005, he has been Professor in the Department of Biochemistry and Molecular Biology at the University of Chicago, with a joint appointment as Senior Computational Biologist at Argonne National Laboratory.
