Feng Bao 鲍峰

I am a new PI at Fudan University. My research involves general learning approaches and their applications to biological and medical studies as well as drug screens.

We are looking for highly motivated students and postdocs to work together.

Previously, I was a Postdoc working at Altschuler and Wu lab, University of California, San Francisco. I obtained my PhD from Tsinghua University in 2019.

Enhancing the spatial resolution of diverse spatial omics platforms by joint generative modeling of space, image and omics

Tissue image (e.g., H&E) is always available along with the generation of spatial omics data. A typical tissue image can be in extremely high resolution (usually at least millions of pixels, note 1 million is just 1000 x 1000 pixels, smaller than the resolution of an iPhone photo) compared with the spatial omics resolution (usually in thousands). A natual idea is to use the high-resolution image to guide the enhancement of low-resolution omics. We tested this idea through a generative modeling of spatial coordinates, image and omics. It works for different omics types, spatial technologies and the recently emerging spatial multiomics. The work was published in Nature Communications.

Multi-modality structured embedding for spatially resolved transcriptomics analysis

Decomposing cell heterogeneity of complex biological systems is an important step to the comprehensive understanding of their organizations and mechanisms. Transcrptomics and imaging are two most widely used approaches to study tissue heterogeneity. Here we try to combine information from these two modalities and provide more extensive dissection of subpopulations in tissues. We follow two principles in design: (1) structured information from single modality (e.g. apparent subpopulations) are preserved after combinations; (2) corrupted information in one modality will not pollute the others.

Deep association kernel learning to explain the genetic causality for complex diseases

Causal loci contribute to complex diseases in various manners. The comprehensive identification of suspicious genes requires a general genome-wide association study (GWAS) model that can work with different types of genetic effects. Here, we try to use a trainable framework to automatically detect these associated positions meanwhile provide a statistical significance quantification. This work was published as a cover paper in the new Machine Learning Journal of Cell Press [_Patterns_](https://www.sciencedirect.com/journal/patterns/vol/1/issue/6).

Recurrent neural network for single-cell RNAseq imputations

scScope is a deep-learning based approach that can accurately and rapidly identify cell-type composition and transcriptional state from noisy single-cell gene-expression profiles containing dropout events and scale to millions of cells. This work was published in Nature Methods.
