🧑🏻💻 About me
🎓 I’m a third-year Ph.D. Candidate in Computer Science at the Center for Computational Biology, Johns Hopkins University, working with Steven Salzberg and Mihaela Pertea. My academic journey started in Electrical Engineering at National Taiwan University (NTU), shifting towards computer science in my final year at the College of Engineering & Computer Science at Australian National University (ANU).
🧬 My research interest intersects deep learning with genomics and transcriptomics:
- 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).
- In genome assembly, I assembled and annotated the first gapless Southern Chinese Han genome, Han1, using PacBio HiFi and Oxford Nanopore long reads, with T2T-CHM13 as a guide (Learn more).
- For pangenome indexing, I applied new renaming heuristics and an SMT solver to make the Wheeler graph recognition problem computationally feasible (Learn more).
- 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).
💻 I am an advocate for open-source software, embracing the philosophy of “build what you need, use what you build”. I invite you to explore my NEWS page for the latest updates on my projects.
