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.

1. Regulatory mechanisms in complex tissues. 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 deep learning algorithms for enhancer-GRN construction and rare cell population discoveries in cases, such as aging cells and minimal residue diseases. https://bmblx.bmi.osumc.edu/iris

2. Immuno-oncology. Single-cell multi-omics has brought transformative insights into immuno-oncology, demonstrating success in describing novel immune subsets and defining important regulators of antitumor immunity. One significant challenge in immuno-oncology is identifying the heterogeneity of immune cells in tumors and their differentiation process. To overcome these limitations, a scMulti-omics study can offer detailed identification of diverse immune subsets at a higher resolution and provide an opportunity to understand the contribution of immune cells to tumor progression. Our lab endeavors single-cell applications in immuno-oncological areas. https://bmblx.bmi.osumc.edu/sc-io

3. Tissue module in human diseases. Spatially resolved technologies (e.g., Visium or CosMx MSI) provide new ways to study cell-cell and cell-environment relations in human diseases at either the cellular or tissue level. It is challenging to understand how a tissue (or an organ) forms and organizes functional regions and the underlying cellular and molecular mechanism from spatial omics data. Our project aims to explore graph representation methods along with deep neural networks to investigate tissue structures and functional behaviors. The long-term goal is to harmonize cellular and tissue biology and demystify how Intra-/extra-cellular activity affects tissue development or disease progress from spatial and single-cell multi-omics. https://bmblx.bmi.osumc.edu/spatial

4. Neurodegenerative disease. Single-cell RNA-sequencing (scRNA-seq) and single-nucleus RNA-sequencing (snRNA-seq) studies have provided remarkable insights into understanding human brains. Our lab takes the advantage of single-cell multi-omics and spatial transcriptomic data to discover the mystery of the molecular mechanisms in neural systems and the pathogenesis of Alzheimer’s disease (AD). https://bmblx.bmi.osumc.edu/neuron

5. Microbiome and host interactions. 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
