Electrical Fluctuations in Polyelectrolytes (eBook)

Prof. Dr. José Antonio Fornés studied Physics at La Plata University, Argentina, where he received his doctoral degree in Physics in 1972. In 1973 he worked as a postdoctoral fellow in Quantum Chemistry at Uppsala University, Sweden. In 1974 he was a postdoctoral fellow at Middlesex Hospital Medical School of London University, in experimental biophysics. He was visiting Professor at the University of California at Irvine, Department of Physiology and Biophysics, during 1989-1991. Also, he was visiting Professor at the Department of Physics of São Paulo University, Brazil, during 1998-2001. He was visiting professor at the Department of Applied Physics of the Complutense University in Madrid, Spain, during 2005-2006. He has been full Professor of Physics at the Department of Physics of the Federal University of Goiás during 1981-1998, and retired after that. His research interests comprise electrical fluctuations in molecular systems, molecular biophysics, hydrodynamic fluctuations as well as molecular motors.Book title:
