Head of Applied Physics Research, Dr Melvin M. Vopson

Applied Physics is a generic term that refers to the branch of Physical Sciences dealing with practical aspects of Physics research and translation of fundamental science and discoveries into practical applications.  Applied Physics includes therefore both physics and physical engineering and it virtually covers all aspects of Physics Research, Science and Technology.

The Applied Physics Research program at the University of Portsmouth focuses on Applied Advanced Materials Science research with emphasis on preparation of multi – functional materials and development of novel materials characterization metrologies. Areas of applicability of our research include sensor technologies, data storage, energy harvesting and solid state cooling technologies.
