Prostate Cancer Disparities
in Charlotte Metro Area
in Charlotte Metro Area
Our analysis shows that prostate cancer patients from lower socioeconomic status (SES) backgrounds are more likely to be diagnosed with high-risk prostate cancer. Age was the strongest predictor, while SES had a greater impact than race.

Tire Modeling
Tire Modeling
In this project, we utilize the invariance principle to scale tire models that optimize race car performance by aligning with both controlled experimental data and track data obtained using Wheel Force Transducers (WFT). The goal is to develop models that agree with data across multiple environments.

Aflatoxin Prediction in Standing Crops
The goal of this project is to develop a general predictive modeling framework for calculating mycotoxin incidence in US crop fields. Prediction and control of the most potent carcinogenic mycotoxin, aflatoxin, is a fundamental challenge for US grain industry, poultry producers, and makers of dairy products.

Causal Modeling of
Affective Polarization
Affective Polarization
The objective of this project is the development of an interactive causal modeling framework to understand affective polarization. The focus is on bridging the gap between data-driven methods for discovering causal relations and expert domain knowledge to mitigate the impact of data limitations.

Deep Learning for
Surface Chemistry
Surface Chemistry
In this project, we are using computational catalysis and deep learning to improve the analysis and understanding of surface chemistry. We will use large datasets of DFT energies and advanced neural networks to identify invariant material and molecular descriptors that can help us predict the behavior of chemical systems.

From Causal Pairs to Causal Graphs
The paper proposes new methods for causal structure learning from observational data using probability distributions informed by cause-effect pair features. These methods are compared to traditional and state-of-the-art approaches on synthetic and real datasets, and have similar or better performance while being computationally faster.
Concept-Driven NOTEARS
(CD-NOTEARS)
(CD-NOTEARS)
CD-NOTEARS extends the widely-used NOTEARS method by incorporating concept-level prior knowledge to impose causal structure on concepts rather than raw high-dimensional data. Our approach, evaluated on synthetic, benchmark, and real-world datasets, outperforms the original NOTEARS, offering a powerful tool for causal discovery in scenarios where concept-level causality is critical.
Invariant Molecular Representations
The study introduces a machine learning method with Siamese neural networks to efficiently predict adsorption energies, using data from multiple density functional theory (DFT) functionals, significantly enhancing accuracy and robustness in catalyst screening, especially for propane dehydrogenation on platinum catalysts.
