Workshop Description (Intermediate Course)

As we step into the era of precision medicine, the need for extensive genomic data analysis is more pressing than ever. With the advent of high-throughput technologies, a plethora of genomic, transcriptomic, and epigenomic datasets from cancer patients have been sequenced, providing a wealth of data for systematic bioinformatics analysis. This workshop is tailored to assist cancer bioinformaticians, postdoc researchers, and graduate students who are interested in incorporating expansive cancer genomic datasets from an open-source platform – The Cancer Genome Atlas (TCGA) – into their research.
 Enrolled participants will gain insights into the fundamental principles of TCGA, including the different data categories and structures, methods for downloading data, and basic pipelines for data analysis within the TCGA platform. The workshop will also provide a versatile R script scaffold for mining TCGA datasets, empowering attendees to analyze their own unique cohorts of cancer genomic datasets.

Technical Requirements



Dr. Xianglong Tan is a postdoctoral researcher in Dr. Michael Carey’s Lab at UCLA. He earned his Ph.D. from Tsinghua University, focusing on protein regulation via post-translational modifications. At the Carey Lab, Xianglong’s research delves into how gene transcription is influenced by enhancers through 3D genome interactions, and how these aberrant interactions can lead to oncogenic expression in lung cancer.
