A postdoctoral position is open in the laboratory of Dr. Charles E.Rogler to carry out investigations into the mechanisms of miRNA action in liver stem cell differentiation. A foundational publication ( Hepatology, 2009, see below) has established an experimental system for miRNA regulated differentiation of liver stem cells to either the hepatocytic or bile ductular cell fates. Initial investigations demonstrate that TGFb signaling molecules, Smads, are targets of differentially expressed miRNAs. This position will carry out investigations to uncover molecular mechanisms of miRNA regulation of the important TGFb signaling pathway and effects on stem cell fate.
Applicants should have a broad base of experience in biology, molecular genetics and biochemistry. Albert Einstein College of Medicine is an equal opportunity employer. Please send CV and names of referees to email@example.com.
