About Me

Hi! I am an incoming Ph.D. student in Computational Biology (CPCB) at Carnegie Mellon University, affiliated with the School of Computer Science. My research is motivated by a central question: how can we extract reliable biological insight from noisy and incomplete data?

During my military service as a medic, I witnessed how clinical decisions were often made under uncertainty due to limited and imperfect data. This experience led me to pursue computational approaches, adding a second major in Computer Science to build a rigorous foundation in algorithms and statistical modeling.

At the University of North Carolina at Chapel Hill, I worked in Prof. Terry Fureys lab on epigenomic method development. There, I developed WAD, a wavelet-based framework for bulk ATAC-seq deconvolution that addresses the intrinsic sparsity and noise of chromatin accessibility data. More broadly, I am interested in building robust and interpretable computational methods for understanding gene regulation from complex genomic data.

WAD: a wavelet-based linear programming method using L1-minimal reconstruction loss for accessible chromatin data deconvolution

Jeongho Chae, Benjamin McMichael, Terrence S. Furey

Preprint 2025

We present WAD (Wavelet-based Accessible chromatin Deconvolution), a principled framework for robust estimation of cell type composition of bulk accessible chromatin data such as from the ATAC-seq assay. To determine informative reference cell profiles from single-cell accessible chromatin studies, WAD leverages wavelet-based denoising to suppress stochastic noise while preserving local chromatin continuity. Cell type proportion inference is reformulated as an L1-minimal linear programming problem, enabling scalable and interpretable solutions. Across 700 in silico pseudo-bulk mixtures generated from single-cell data, WAD achieved a consistently lower mean absolute error (MAE) and higher concordance (r > 0.85) than existing machine learning-based methods. These results demonstrate that wavelet-based feature extraction provides a biologically grounded and computationally efficient approach to chromatin signal deconvolution.
