Research Interests

 

Artificial intelligence (AI) and single-cell studies have been making waves in the science and technology communities. AI offers a broad range of methods that can be used to investigate diverse data- and hypothesis-driven questions in single-cell biology. The highly heterogeneous nature of single-cell data can be analyzed across a wide range of research topics by generalizing deep-learning model design and optimization in a hypothesis-free manner. Our lab focuses on the research of single-cell multi-omics data, aiming to develop cutting-edge computational tools to discover underlying mechanisms in diverse biological systems.

Highlighted Projects

Single-cell multi-omics (scMulti-omics) allows for the generation and quantification of multiple modalities simultaneously to fully capture the intricacy of complex molecular mechanisms and cellular heterogeneity. Such technology reshapes the investigation of cellular heterogeneity and yields novel insights in neuroscience, cancer biology, immuno-oncology, and therapeutic responsiveness. We seek to develop an end-to-end and hypotheses-free deep learning framework (DeepMAPS) to take the advantage of heterogeneous graphs and graph transformers in elucidating cellular heterogeneity and inferring cell-type-specific biological networks. https://bmblx.bmi.osumc.edu/  


Spatially resolved transcriptomics provides a new way to define spatial contexts and understand the pathogenesis of complex human diseases. It is challenging to accurately characterize tissue architectures and the underlying biological functions from spatial transcriptomic. Our project aims to use graph neural networks to reconstruct tissue architectures and identify spatially variable genes and specific regulatory relations. Another goal is to identify cell-cell communications as well as signal transduction regulatory networks from spatial transcriptome data. https://bmblx.bmi.osumc.edu/spatial


Our lab focuses on developing computational methods to discover heterogeneous transcriptional regulatory mechanisms from single-cell sequencing data. Our efforts are split between inferring cell-type-specific regulatory signals and constructing reliable gene regulatory networks via the integration of single-cell multi-omics. We are also going into the development of novel computational algorithms for spatial transcriptomic data analysis in immuno-oncology and neuroscience. https://bmblx.bmi.osumc.edu/iris


We are developing enabling tools and databases, using metagenomic and metatranscriptomic data, to elucidate microbial systems and their interactions with human diseases. Our goal is to deliver reproducible and integrated analyses of complex gut microbiome data, detect functional and taxonomic abundances (biomarkers) in a microbial community, and infer significant associations between clinical measurements of human diseases and transformed microbial biomarkers. https://bmblx.bmi.osumc.edu/magical
