Brief Description

Dr. Dev is an assistant professor in the Howard University Department of Physics and Astronomy.  Research in Dev’s group focusses on exploring and elucidating the fundamental physics governing structural, electronic and optical properties of materials using Density Functional Theory-based computational methods.  Of particular interest are modification in properties through atomic-scale structural changes within conventional bulk systems, as well as novel 2D materials. These investigations often have important technological relevance in a range of applications such as dye-sensitized solar cells, chemical sensors and quantum technologies.
