🧬 My research interest intersects **"graphs"** with genomics and transcriptomics:


- In **deep learning in genomics**, my work focuses on utilizing sequence models to decode patterns in DNA sequences, aiming to uncover insights into the transcriptional regulatory networks that integrate cis-regulatory DNA sequences with the activity of trans-regulators. I am developing a yeast large language model (LLM) to better understand the mechanisms of yeast gene expression regulation.
- In **splice site prediction**, I built a deep dilated residual convolutional neural network to decode the complexities of RNA splicing and understand the impact of genetic variants on cryptic splicing ([Learn more](https://www.biorxiv.org/content/10.1101/2023.07.27.550754v2)).
- In **genome assembly**, De Bruijn graphs are widely used. For an example of its application, check out my [Han1 assembly](https://doi.org/10.1093/g3journal/jkac321), the first gapless Southern Chinese Han genome.
- For **pangenome indexing**, I've contributed to making the Wheeler graph recognition problem computationally feasible through innovative heuristic methods combined with an SMT solver ([Learn more](https://doi.org/10.1016/j.isci.2023.107402)).
- In **genome annotation**, I have utilized graph-based methods to stitch together fragmented DNA and protein alignments, thereby assembling them into more accurate annotations. ([Learn more](https://doi.org/10.1101/2024.05.16.593026)).
- In **transcriptional regulatory networks**,my work uses sequence models to decode DNA patterns, aiming to uncover insights into how cis-regulatory DNA sequences and trans-regulators interact. I am developing a yeast large language model (LLM) to better understand the mechanisms of yeast gene expression regulation.
- In **splice site predictiong**, I built a deep dilated residual convolutional neural network to decode the complexities of RNA splicing, alternative splicing, and the impact of genetic variants on cryptic splicing ([Learn more](https://www.biorxiv.org/content/10.1101/2023.07.27.550754v2)).
- In **genome assembly**, I assembled and annotated the first gapless Southern Chinese Han genome, [Han1](https://www.ncbi.nlm.nih.gov/datasets/genome/GCA_024586135.1/), using PacBio HiFi and Oxford Nanopore long reads, with T2T-CHM13 as a guide ([Learn more](https://doi.org/10.1093/g3journal/jkac321)).
- For **pangenome indexing**, I applied new renaming heuristics and an SMT solver to make the Wheeler graph recognition problem computationally feasible ([Learn more](https://doi.org/10.1016/j.isci.2023.107402)).
- In **genome annotation**, I used graph-based methods to stitch together fragmented DNA and protein alignments, thereby assembling them into more accurate annotations. ([Learn more](https://doi.org/10.1101/2024.05.16.593026)).
<!-- - My **transcriptome assembly** work focuses on modeling RNA-Seq data using directed acyclic splice graphs, with ongoing research into graph neural networks to decode the complexities of RNA splicing. ([Learn more](https://www.biorxiv.org/content/10.1101/2023.07.27.550754v2)). -->
