Megumi joined Imperial College London as a physics undergraduate student in 2006 and worked on molecular upconversion in 2009 (funded through Imperial College London UROP scheme), luminescent solar concentrator in 2010-2011 as a part of MSci project. She started PhD project to investigate ways to achieve intermediate band solar cells using quantum well structures in 2010, which was joinly funded by SHARP laboratory of Europe, Imperial College International Scholarship 2010, Imperial College London department of Physics and EPSRC. She started working as a research assistant in 2014 under EPSRC funded "The Quantum Ratchet Concept for Ultra efficient Solar Cells" and promoted to a research associate after being awarded PhD in 2015. She is currently looking at the ways to achieve quantum rachet intermediate band solar cells using a multi quantum well super-lattice and organic moleculs.
