Section Staff

Luis Diaz, Post-Baccalaureate Fellow

Luis graduated from Pomona College in 2015 with a BA degree in molecular biology. He is working on regulation of the Myb gene in erythroid cells. While conducting his research this year, Luis is applying to MD/PhD programs.

Xiang Guo, Postdoctoral Fellow

Xiang received her PhD from the Institute of Genetics and Molecular Biology, Chinese Academy of Sciences in 2015. She is studying the negative regulatory role of the ETO2 protein as part of a complex in erythroid cells that facilitates enhancer looping (or folding) of chromatin.

Maria Soledad Ivaldi, Postdoctoral Fellow

Soledad received her PhD in Molecular Biology and Biochemistry in 2009 from Johns Hopkins University where she studied under Victor Corces. She is working on the function of a long non-coding RNA in regulation of human globin genes.

Ivan Krivega, Research Fellow

Vanya studied under Pavel Georgiev at the Institute of Gene Biology, Russian Academy of Sciences and received his PhD in 2007. He is studying the molecular mechanisms underlying how enhancers function.

Benjamin Leadem, Postdoctoral Fellow

Ben received his PhD in 2015 from Johns Hopkins University where he studied under Steve Baylin. Ben is using genome wide approaches to discover epigenetic modifiers in erythroid cells that are important for genome modification during development.

Guoyou Liu, Postdoctoral Fellow

Guoyou received his PhD in 2015 from Peking University Medical School (PUMC) where he trained under De-Pei Liu. Guoyou is working on regulation of key erythroid genes by non-coding RNAs.

Jun Zhang, Biologist

Jun was trained as an MD in China. She did post-doctoral work at Duke University. Jun is working on the functional role of chromatin loops mediated by the insulator protein CTCF in the region of ch11 surrounding the human globin genes.
