Our lab focuses on next-generation sequencing data analysis, software development and the application of machine learning to bioinformatics and medical imaging.
NGS has become the standard tool to the quest to understand genomics, epigenomics and their relationship to human diseases. We have extensive experience analyzing large-scale NGS data. In the past few years, our group has analyzed more than 10,000 NGS samples in the total of more than 100TB in collaboration with researchers from Mount Sinai as wells as other institutes. Based on these results, we have published many papers in top-tier journals, such as Nature, Science, Nature Medicine and Nature Genetics.
We are also actively participating in developing software tools for NGS data analysis. Two examples are ngs.plot and diffReps. ngs.plot is a very popular tool for NGS data visualization and exploration. It is very versatile and memory efficient. Since its publication in 2015, the paper has been cited for more than 400 times. diffReps is a package for the differential analysis of ChIP-seq (count) data, taking into consideration of biological replicates. It is also popular among bioinformaticians.
Machine learning is an essential tool for building models on complex, high-dimensional data. Besides our daily usage of clustering, dimensionality reduction and generalized linear models on high-throughput biological data, we have also made contributions in the following two fields: automated genome segmentation and mammography based detection for breast cancer. Genome segmentation aims to label the genomic sequence with functional categories using large-scale ChIP-seq data, which is generally an unsupervised problem, or semi-supervised at most. We combined hidden Markov models with artificial neural networks to significantly improve the accuracy from previous methods. In breast cancer detection, the goal is to predict a patient’s likelihood to develop cancers within a certain period based on mammograms. We developed deep learning models based on convolutional neural nets to achieve top-notch performance.
Machine learning is an essential tool for bioinformatics, genomics and biomedical imaging. Dr. Shen has a long-term interest in machine learning research and its application to the bioinformatics field. His recent interests include:

During his postdoctoral training at UCSD, Dr. Shen studied transcriptional regulation using genomic data and computational methods. His main contributions include:
- Predicting gene expression from DNA sequences using Bayesian networks:
– L. Shen, J. Liu, and W. Wang, “GBNet: Deciphering regulatory rules in the co-regulated genes using a Gibbs sampler enhanced Bayesian network approach,” BMC Bioinformatics, vol. 9, no. 1, p. 395, 2008.

During his Ph.D. study, Dr. Shen studied the problem of cancer classification using microarray data. His main contributions include:
- Binary cancer classification using dimensionality reduction and logistic regression:
– L. Shen and E. C. Tan, “Dimension Reduction-Based Penalized Logistic Regression for Cancer Classification Using Microarray Data,” IEEE/ACM Transactions on Computational Biology and Bioinformatics, vol. 02, no. 2, pp. 166–175, 2005.

– L. Shen and E. C. Tan, “Reducing multiclass cancer classification to binary by output coding and SVM,” Computational Biology and Chemistry, vol. 30, no. 1, pp. 63–71, 2006.
- ngs.plot is a very popular tool for NGS data visualization and exploration. It features a very versatile pipeline that allows anyone to visualize sequence alignment pileups at a collection of genomic regions and summarize the enriched patterns. It is carefully engineered to index and read large NGS data efficiently without causing memory explosion. Since its publication in 2015, the paper has been cited for >170 times. Access the paper here.
- diffReps is a tool for ChIP-seq differential analysis considering biological replicates. Differential analysis is one of the most commonly performed tasks for biological studies, which needs to consider both mean differences and variation among two or more groups. There are many programs for comparing RNA-seq samples but much less for comparing ChIP-seq samples. The main reason is that ChIP-seq is more difficult to deal with because there is no predefined region and the entire genomic sequence has to be considered. diffReps uses a sliding window approach to perform millions of negative binomial tests on the genomic sequence and then merge and summarize the results into a text report. Since its publication, it has remained one of the most popular tools for ChIP-seq differential analysis.
- GeneOverlap is a small utility package for comparing multiple gene lists and determine the significance of their overlaps. It solves the statistical problem with Fisher’s exact tests. Although relatively simpler than ngs.plot and diffReps, it is among the top 20% downloaded packages on Bioconductor. Why is that? It’s simply because people have so many gene lists to compare against one another!
- Our lab has also developed SPEctRA – an RNA-seq processing pipeline and chip-seq_preprocess – a ChIP-seq preprocessing pipeline. Both feature multi-processing and can run seamlessly on an HPC cluster or a local workstation.
