High-throughput sequencing technology allows scientists to quickly and accurately sequence multiple DNA molecules in parallel and is an indispensable tool for studying human diseases including cancer. However, a major challenge is how to integrate and interpret this large amount of data using advanced computational methods.
As a bioinformatician, my research focus is on using an integrative approach to analyze data from whole genome sequencing, whole exome sequencing, ChIP-seq, ATAC-seq and RNA-seq as well as other data generated from 3D genome structure, metabolomics, and proteomics. By developing and implementing bioinformatics methods and algorithms, I am working to discover the gene regulatory mechanisms responsible for normal blood development and blood disorders such as leukemia.
About Dr. Zhang
Yuannyu Zhang received her Ph.D. in Bioinformatics from Harbin Medical University, where she studied the molecular features of cancer-associated genes. In 2012, she started her postdoctoral training at Shanghai Jiao Tong University School of Medicine, and developed new computational pipelines to identify candidate cancer driver genes by integrating genomics data in liver cancer. From 2014 to 2017, she was an assistant professor at CAS-MPG Partner Institute for Computational Biology at the Chinese Academy of Sciences. She collaborated with Dr. Jian Xu at Children’s Medical Center Research Institute (CRI) at UT Southwestern as a visiting scholar and developed computational methods for analyzing chromatin interactions identified by biotinylated dCas9-mediated CAPTURE. In 2017, she joined CRI and UT Southwestern as a postdoctoral researcher where she studied pathogenic non-coding variants, structural variants, and epigenetic alterations in hematopoietic malignancies.
In 2020, she was promoted to an assistant professor at CRI.
