Pedro Rocha - PI

I studied Microbiology and Genetics in Portugal, at Lisbon University, and graduated in 2005. I then moved to Germany for my PhD where I worked in the lab of Heiner Schrewe at the Max-Planck Institute for Molecular Genetics in Berlin, studying the role of transcriptional co-regulatory complexes during mouse development, as part of a Marie Curie-sponsored international consortium. For my postdoctoral training I moved the United States and joined the lab of Jane Skok at New York University, to explored multiple ways by which nuclear organization maintains genomic integrity. Our lab at NIH, started in May of 2018 and we focus on understanding how the mechanisms that fold the genome contribute to regulation of gene expression and cell-fate decisions.

Nina Kopitchinski – Lab Manager

Nina Kopitchinski.I am a Research Specialist mainly focusing on generating transgenic mice from genetically altered mouse embryonic stem cells. I gained most of my knowledge at the Goethe University in Frankfurt, Germany, where I worked as a lab manager and transgene specialist. At NICHD I want to support my team and its individual scientific projects as much as possible to help them achieving their goals. For myself, I hope to gain a better understanding of the epigenetic mechanisms and genome structure related to embryonic development and to expand my knowledge of genetics in general. Nina started March 2020. Check Nina’s publications here.

Joyce J Thompson - Postdoctoral Fellow

Joyce ThompsonMy long-term research interest lies in understanding how epigenetic mechanisms acting at different levels coordinate and regulate chromatin organization across development and differentiation, and their contribution to cell-fate decisions. During my graduate studies I focused on characterizing a zinc-finger protein and identify its role in modulating epigenetic mechanisms.  As a postdoc in the Rocha lab, I will be studying how the chromatin is organized in the early embryo, and what factors are crucial in establishing sub-chromosomal domains and facilitating chromosomal interactions. Joyce started in October 2018. See a list of Joyce's publications here!

Shreeta Chakraborty - Postdoctoral Fellow

Shreeta ChakrabortyMy longterm research goal is to unriddle how gene regulation executes a diverse repertoire of high fidelity response during cell fate decisions at the critical stages of development and differentiation. During my graduate studies my research focus was to elucidate the function of a protein called Nostrin in the different aspects of utero-placental development including trophoblast stem cell differentiation and feto-maternal angiogenesis. In the Unit on Genome Structure and Regulation at NIH, I will be exploring and investigating how a milieu of transcription factors, enhancers and promoters coordinate cell fate based upon chromatin architecture during early mammalian development. Check Shreeta's publications.

Zhenyu Zuo - Postdoctoral Fellow

Zhenyu ZuoMy long-term research interest is to understand the regulatory mechanisms controlling cell fate transitions in embryonic stem cells and during early embryo development. My Ph. D project mainly focused on functions of protein arginine methyltransferase I (Prmt1) in ES cells and mouse early embryo development. In the Rocha lab, I will continue to explore regulation of gene expression during early cell fate decisions. Especially, I want to investigate the global changes of genome structure during cell fate decision processes and find out how these changes coordinate with lineage choices and what may be the key factors governing these systematic changes. Zhenyu starts November 2019. See papers by Zhenyu.

Carolina M Montano – Laboratory of Genetics and Genomics Fellow

Photo of Carolina MontanoMy long-term goal is to understand the role of DNA methylation and chromatin alterations in disease and to bring those insights back to clinical care. During my MD/PhD training, I studied genome-wide DNA methylation across different tissues of patients diagnosed with schizophrenia. After completing Pediatrics residency at Boston Children’s Hospital and Clinical Genetics and Genomics residency training at NHGRI, I enrolled in the Laboratory Genetics and Genomics Fellowship to develop expertise in clinical cytogenetic and molecular genetic analyses. Through a collaboration with the Johns Hopkins School of Medicine and the Unit on Genome Structure and Regulation, we are investigating novel pathogenic variants, methylation changes, and other epigenetic processes that could contribute to the pathogenesis of Maffucci syndrome and Ollier Disease. See Carolina’s publications.
