Data-driven design of organic electronics materials

Designing of organic materials for electronic applications has followed the Edisonian techniques of trial and error. Such a approach is both time-consuming and expensive. My research involves investigating the correlations in already synthesized materials and proposing new materials with the aid of quantum chemical calculations and machine learning models.
