Prof. So’s research interest focused on molecular mechanisms of transcriptional regulation and functional genomics in mammalian development and human congenital disorders. He is interested in studying mechanisms of transcription regulation during craniofacial development, including transcription factors (TFs), non-coding RNAs (ncRNAs), enhancers and RNA binding proteins (RBPs) using multi-omics and next-generation sequencing approaches in stem cells and organoids. Multiple projects are available under this theme:

1. Using functional genomics approach to identify genetic factors for congenital craniofacial malformations
2. Elucidating transcription regulation in skeletal myogenesis
3. Elucidating extrinsic factors in regulating skeletal myogenesis
4. Study of neurogenic placode formation stages and gene regulatory networks using single-cell RNA-seq and organoid culture
