Research Interests

I am interested in the electronic and optical properties of organic semiconductor materials with potential applications in different areas of technology, such as organic solar cells and LEDs. Specifically, I focus on the theoretical understanding of ultra-fast processes in these materials, including charge transfer, singlet exciton fission and exciton transport. These processes may all be encountered in different devices based on organic semiconductors, and understanding how realistic conditions affect them is a crucial step towards wide-spread application. To this end, factors such as  molecular vibrations and environment polarity are included in our models, capturing effects that have long remained out of reach. Understanding the quantum mechanical dynamics of these systems could contribute towards a next generation of efficient optoelectronic devices based on organic materials.
