Research topics:

My research explores the intricate structure-property relationships of organic dyes to enhance their performance in diverse applications such as bioimaging, biosensing, therapeutic interventions, and photocatalysis. At the core of our work is computational modeling, which we use independently and in collaboration with synthetic chemists to systematically analyze these relationships and establish rational design principles for specific functional requirements.
