CAS Key Laboratory of Genomic and Precision Medicine

TIAN Chenxi

Group leader

TIAN Chenxi is a Principal Investigator in CAS Key Laboratory of Genomic and Precision Medicine in Beijing Institute of Genomics, Chinese Academy of Sciences. Dr TIAN received her B.S degree from Tsinghua University in 2006 and Ph.D. degree in developmental biology from Cornell University in 2013. She then moved to MIT in the laboratories of Dr. Richard Hynes to perform research first as a postdoctoral fellow, then as a research scientist. She was recruited as a principal investigator in BIG, CAS in 2021.

Introduction

Dr. TIAN’s research interest lies in tumor microenvironment (TME), and more specifically, extracellular matrix (ECM) in the TME. Her research goal is to spatially delineate TME to understand the functional consequences and use TME components as drug and diagnostic reagent delivery targets. She has published in renown peer-reviewed journals including Nature Communications, PNAS, Cancer Research, etc. She was awarded the prestigious Damon Runyon Postdoctoral Fellowship.

Current research interests

1. Characterization of tumor spatial microenvironment by developing antibody-barcode-conjugate to localize extracellular proteins and transcriptomes by spatial RNA sequencing.

2. Functional interrogation of cell-cell and cell-matrix interactions in the TME

3. Using the tumor-specific/associated ECM changes to develop tumor-targeting nanobodies for non-invasive diagnostic imaging and therapeutics.
