Available Postdoctoral Position Details
Posted: 4/14/2020

The Choi Lab is seeking a highly motivated, recent PhD or MD/PhD graduate to participate in gastric cancer research.


The Choi Lab studies basic and pre-clinical research projects to understand mechanisms of carcinogenic transition in gastric carcinogenesis. The Choi Lab is a multiple (NCI and DOD) funded gastric cancer research laboratory and uses novel in vivo mouse models and in vitro dysplasia organoid models which are unique in the gastric cancer field.


Positions are available to understand the biology of gastric carcinogenesis and oncogenic roles of Kras activation in the stomach and to assess functional roles of Sox9 as a putative master regulator of metaplasia development and progression.


Specific techniques for these studies include Animal surgical techniques, Single cell RNA sequencing, 3D organoid culture, Live cell/organoid microscopy and Multiplex fluorescence imaging and analysis.

Common techniques include Molecular biology, cell biology and Confocal fluorescence microscopy.  


Successful candidates:

1. A PhD degree in cell biology or cancer biology

2. A track record of original publications, with at least one first authored scientific publication

3. Experience with mouse transgenic models

4. Strong communication skills in English, oral and written

5. One or two first-author peer-reviewed publications


If interested, please contact Eunyoung Choi, eunyoung.choi@vumc.org, with a full CV, three references, earliest start date and a statement with career goal and research experience.
