Research Associate - 122466

The Division of Gastroenterology in the Department of Medicine at UC San Diego aims to conduct cutting-edge research in digestive diseases and to promote scholarly investigations, teaching, service and health leadership and training.

Under general supervision of the Principal Investigator, the Research Associate will perform cellular and animal lab experiments. Incumbent will independently develop multiple research projects about intestinal microbiota and its relationship with liver disease, will be responsible for self-designing and conducting experiments using various animal models, as well as performing relevant human study analysis. Will generate animal models of alcohol-related liver disease, non-alcoholic fatty liver disease and primary sclerosing cholangitis by using genetically modified animals, together with the adjusted feeding protocol. Will then perform numerous experiments using molecular biology techniques such as Confocal Immunofluorescence Imaging, immunohistochemistry, FACS, ELISA, Western Blotting, PCR, RT-qPCR, drug treatment on those animals, with the knowledge of biochemistry, cell biology, molecular biology, genetics, microbiology, histology and so on. In addition, incumbent will isolate DNA from Alcoholic hepatitis (AH) and NASH patient stools and perform metagenomic sequencing, 16S/ITS sequencing and whole genome sequencing with human samples and further analyze the data with multiple statistical tools. Will independently interpret all the results and eventually generate multiple manuscripts based on the discoveries of these projects. Furthermore, the incumbent will involve the planning, assigning and directing the work of other lab members including visiting scholars and student lab assistants. It also involves training of new hires. Other duties assigned as needed.
