Prof. White received a grant from the National Institute of Health (NIH). The project is titled "Learning to learn in structural biology with deep neural networks." The goal of this research is to develop methods that allow meta-learning
in structural biology to train new deep learning models on tasks where data is scarce, with limited computing resources.

Abstract for Graph Neural Network Based Coarse-Grained Mapping Prediction:
The selection of coarse-grained (CG) mapping operators is a critical step for CG molecular dynamics (MD) simulation. It is still an open question about what is optimal for this choice and there is a need for theory. The current state-of-the art method
is mapping operators manually selected by experts. In this work, we demonstrate an automated approach by viewing this problem as supervised learning where we seek to reproduce the mapping operators produced by experts. We present
a graph neural network based CG mapping predictor called DEEP SUPERVISED GRAPH PARTITIONING MODEL (DSGPM) that treats mapping operators as a graph segmentation problem. DSGPM is trained on a novel dataset, Human-annotated Mappings
(HAM), consisting of 1,206 molecules with expert annotated mapping operators. HAM can be used to facilitate further research in this area. Our model uses a novel metric learning objective to produce high-quality atomic features
that are used in spectral clustering. The results show that the DSGPM outperforms state-of-the-art methods in the field of graph segmentation.
