Green Center for Reproductive Biology Sciences
Laboratory: Banaszynski Lab

Research: Dr. Banaszynski studies epigenetic contributions to gene expression and genome stability in mammalian systems. Her research focuses on the dynamic regulation of chromatin states at both coding and non-coding regions including the influence of histone variant incorporation on histone post-translational modification states. Her long-term goal is to improve our understanding of the chromatin-based mechanisms regulating fundamental cell-fate decisions in pluripotency and differentiation that are essential to our understanding of developmental processes.

Laboratory: Hon Lab

Research: Our primary research interest is to develop a comprehensive understanding of how the millions of non-coding regulatory elements encoded in our genomes precisely coordinate gene expression in developmental and disease contexts. A major focus is elucidating how genetic and epigenetic dysregulation of transcriptional enhancers supports a cancer cell’s altered transcriptional program. To accomplish this, we take a systems biology approach: developing and employing integrative techniques at the interface of gene regulation, epigenetics, functional genomics, and bioinformatics.

Laboratory: Liu Lab

Research: The overarching goal of the Liu lab is to understand the cellular regulation of dynamic chromatin structure in both normal and diseased cells. The Liu lab is particularly interested in elucidating structure and function of large chromatin complexes that regulate epigenetic inheritance and cell fate determination during development. To achieve the research goal, the Liu lab leverages a combination of a series of advanced research tools, including biochemical reconstitution (e.g. protein-protein, protein-nucleosome, and protein-non-coding RNA complexes), X-ray crystallography, cryo-EM, proteomics, and genomics by next-generation sequencing.

Laboratory: Mahendroo Lab

Research: My research interests include an understanding of the molecular mechanisms by which the cervix remodels during pregnancy, parturition and postpartum to allow birth and subsequent recovery of the cervix to the nonpregnant state. Our focus is on understanding the contribution of the extracellular matrix, immune cells, and cervical cells to this process and their regulation during all phases of cervical remodeling.

Research: Mechanisms of non-coding RNAs and their role in gene regulation important for development and cancer. A major focus is the molecular mechanism and regulation of microRNA processing.

Laboratory: Sabari Lab

Research: Our primary goal is to understand how the gene control machinery is organized within the nucleus. We study how nuclear condensates form at specific genomic loci, how they function once formed, and how they are misappropriated in disease. The lab will focus on the roles of protein disorder, regulatory DNA element clustering, non-coding RNA, and active processes in regulating nuclear condensate formation and function.

Molecular Biology
Laboratory: Buszczak Lab
Research:The Buszczak lab studies several Drosophila stem cells lineages as a model for understanding how cells adopt different fates. The long-term goal is to determine the complete regulatory network that controls both the maintenance of Drosophila stem cells and the differentiation of their daughters. We hope to use this information as a foundation for understanding how perturbations in normal gene expression programs cause disease.
