MACHINE LEARNING FOR CHEMISTRY
Molecules are composed of functional groups that behave similarly in different contexts. We are using machine learning to develop quantum chemical methods that take better advantage of this molecular similarity. In particular, we are developing neural networks that use quantum chemistry as an integral part of their prediction process. By training the neural network on data from ab initio computations, the neural net learns to predict molecular properties at a cost that is a small fraction of that of ab initio theory. We are also developing ways to use machine learning to control experimental conditions and drive reactions to desired outcomes.
Computational Modeling of Organic Semiconductors
We use electronic structure theory to probe the structure property relationships of conjugated polymers. This often involves extracting information on the structure and electronic properties of these materials from spectroscopy and other measurements. In our most recent work, we have been exploring how incorporation of heteroatoms into the conjugated backbone influences their properties, and how these properties may be modified by varying the sequence of the polymer units.
