Bio
Hi. This is Xin from the Department of Biomedical Informatics (DBMI) of Harvard Medical School. I recently joined Peter Kharchenko lab for a Consortium effort project and spatial deep learning project with single-cell analysis.
Before coming to Boston, I spent two years at Northwestern University Chicago campus. My previous postdoctoral research focused on the mechanism of gene regulations via single-cell analysis of cancers and machine/deep learning.
I received my Ph.D. in Bioinformatics and Computational Biology at the University of New South Wales in Sydney, NSW, Australia under Joshua Ho in 2018. My Ph.D. research focused on developing machine learning models for the grammar of transcriptional regulation and chromatin state study.
Before coming to UNSW, I got my Bachelor’s degree at Sun Yat-sen University in Guangzhou, China in 2009. I also got my Master of Research degree in 2013 under Dr. Zhongsheng Sun who is a PI in the Beijing Institutes of Biological Science, Chinese Academy of Science(CAS). After master graduation, I was in Biocant Institute (@Portugal) for one year as a Bioinformatician.

Predict the functional impact of genetic variants via ultra-deep neural networks such as Resnet
Predict the functional impact of non-coding genetic variants is crucial for related diseases' diagnosis and clinical applications. Based on the sate-of-the-art ResNet (Residual neural network paper), a recent published work "SpliceAI" shows unbelievable accuracy on predicting variants caused splicing. I'm quite familiar with SpliceAI as established and re-ran it on our current GPU workstation. It would be a good combination for Resnet structure and other mutation effect predictions such as polyadenylation (manuscript in preparation) or other diseases mutation study with/without the related CRISPR/cas9 cell-line screening data.Single-cell RNA-seq analysis on diseases (e.g. cancers)
Single-cell RNA-seq technology now becomes more and more popular and useful in disease studies as well as related immunotherapy studies. I have the experience on analyzing single-cell RNA-seq data generated from both SMART-seq2 protocol (our chemoresistance index project with Vadim Backman lab) and 10X Genomics protocol (a preliminary exploration analysis collaborated with Kevin Struhl lab). My single-cell RNA-seq analysis on the SMART-seq2 data revealed interesting biology in chemoresistance (manuscript in preparation).Discovery of cell-type specific DNA motif grammar in cis-regulatory elements
I developed a Random Forest (RF) based approach to build a multi-class classifier to predict the cell-type specificity of a TF binding site given its motif content. I applied this RF classifier to two published ChIP-seq datasets of TF (TCF7L2 and MAX) across multiple cell types. Using cross-validation, I show that motif combinations alone are indeed predictive of cell types. I also present a rule mining approach to extract the most discriminatory rules in the RF classifier, thus allowing us to discover the underlying cell-type specific motif grammar.Publications (Google Scholar)
