Maria Barna
Assistant Professor of Genetics and of Developmental Biology
Current Research and Scholarly Interests Our lab studies how intricate control of gene expression and cell signaling is regulated on a minute-by-minute basis to give rise to the remarkable diversity of cell types and tissue morphology that form the living blueprints of developing organisms. Work in the Barna lab is presently split into two main research efforts. The first is investigating ribosome-mediated control of gene expression genome-wide in space and time during cellular differentiation and organismal development. This research is opening a new field of study in which we apply sophisticated mass spectrometry, computational biology, genomics, and developmental genetics, to characterize a ribosome code to gene expression. Our research has shown that not all of the millions of ribosomes within a cell are the same and that ribosome heterogeneity can diversify how genomes are translated into proteomes. In particular, we seek to address whether fundamental aspects of gene regulation are controlled by ribosomes harboring a unique activity or composition that are tuned to translating specific transcripts by virtue of RNA regulatory elements embedded within their 5’UTRs. The second research effort is centered on employing state-of-the-art live cell imaging to visualize cell signaling and cellular control of organogenesis. This research has led to the realization of a novel means of cell-cell communication dependent on a dense network of actin-based cellular extension within developing organs that interconnect and facilitate the precise transmission of molecular information between cells. We apply and create bioengineering tools to manipulate such cellular interactions and signaling in-vivo.

The Ernest and Amelia Gallo Professor in the School of Medicine, Professor of Developmental Biology and, by courtesy, of Chemical and Systems Biology
Current Research and Scholarly Interests Function of Hedgehog proteins and other extracellular signals in morphogenesis (pattern formation), in injury repair and regeneration (pattern maintenance). We study how the distribution of such signals is regulated in tissues, how cells perceive and respond to distinct concentrations of signals, and how such signaling pathways arose in evolution. We also study the normal roles of such signals in stem-cell physiology and their abnormal roles in the formation and expansion of cancer stem cells.

Chloe Girard
Postdoctoral Research Fellow, Developmental Biology
Current Research and Scholarly Interests Crossovers (COs) at meiosis are necessary for a balanced first meiotic division. The number of crossovers, per cell and per chromosome, is tightly regulated, within a narrow range of variation. COs are initiated by double strand-breaks (DSBs) that are then processed either through the ZMM pathway or the MUS81 pathway. But DSBs greatly outnumbers COs in a large set of species. This suggests a conserved mechanism which would limit the number of COs formed despite an excess of CO intermediates.

Antonina Hafner
Postdoctoral Research Fellow, Developmental Biology
Bio I am a postdoctoral fellow in the lab of Alistair Boettiger in the Department of Developmental Biology. I have always been interested in understanding regulatory mechanisms that lead to tissue or cell type specific gene expression. During my PhD in the lab of Galit Lahav at Harvard Medical School, I studied how temporal dynamics of a tumor suppressor transcription factor, p53 regulate the dynamics of gene expression in response to DNA damage. In the Boettiger lab, I'm interested how specificity between enhancer-promoter interactions is achieved using super-resolution microscopy.

Daniel Jarosz
Assistant Professor of Chemical and Systems Biology and of Developmental Biology
Current Research and Scholarly Interests My laboratory studies conformational switches in evolution, disease, and development. We focus on how molecular chaperones, proteins that help other biomolecules to fold, affect the phenotypic output of genetic variation. To do so we combine classical biochemistry and genetics with systems-level approaches. Ultimately we seek to understand how homeostatic mechanisms influence the acquisition of biological novelty and identify means of manipulating them for therapeutic and biosynthetic benefit.

Seung K. Kim M.D., Ph.D.
Professor of Developmental Biology and, by courtesy, of Medicine (Endocrinology)
Current Research and Scholarly Interests We study the genetics of pancreatic islet cell differentiation using molecular, embryologic and genetic methods in several model systems, including mice, embryonic stem cells, and Drosophila. Our work suggests that critical factors required for islet development are also needed to maintain essential functions of the mature islet. Our knowledge of genetic and cellular pathways governing islet formation has allowed us to use stem cell lines to produce islet replacements in vitro.

David Kingsley
Professor of Developmental Biology
Current Research and Scholarly Interests My laboratory uses mice, stickleback fish, and humans to study the molecular basis of vertebrate evolution. Using genetics and genomics, we have tracked down key genes and mutations that control skeletal development, limb patterning, brain size evolution, skin color, salt handling, and susceptibility to arthritis and skin cancer. Many of these genetic mechanisms are used repeatedly, providing new insights into the molecular basis of evolution in many different species, including ourselves.

Kyle M. Loh
Assistant Professor of Developmental Biology
Current Research and Scholarly Interests We have developed a strategy to generate fairly pure populations of various human tissue progenitors in a dish from embryonic stem cells (ESCs). We have delineated the sequential lineage steps through which ESCs diversify into various tissues, and in so doing, developed methods to exclusively induce certain fates at the expense of others. The resultant pure populations of tissue progenitors are the fundamental building blocks for regenerative medicine.

Roeland Nusse
Virginia and Daniel K. Ludwig Professor in Cancer Research
Current Research and Scholarly Interests Our laboratory studies Wnt signaling in development and disease. We found recently that Wnt proteins are unusual growth factors, because they are lipid-modified. We discovered that Wnt proteins promote the proliferation of stem cells of various origins. Current work is directed at understanding the function of the lipid on the Wnt, using Wnt proteins as factors the expand stem cells and on understanding Wnt signaling during repair and regeneration after tissue injury.

Matthew P. Scott
Professor of Developmental Biology, Emeritus
Current Research and Scholarly Interests Our research has been focused on the genetic regulation of animal development and its relation to birth defects, cancer, and neurodegeneration. We studied mechanisms and functions of Hedgehog (Hh) signaling, which controls cell fates and growth, in the context of normal development and brain cancer. We studied a neurodegenerative disease, Niemann-Pick C syndrome, that affects intracellular organelle movements and sterol homeostasis. Due to Dr. Scott's new job, the lab is no longer active.

Bo Wang
Assistant Professor of Bioengineering and, by courtesy, of Developmental Biology
Bio We are a discovery-driven research group working at the interface between statistical physics, developmental biology, and bioengineering. We combine quantitative organism-wide fluorescence imaging ("deep imaging"), functional genomics ("deep sequencing"), and statistical modeling to study systems biology and evolutionary cell biology of flatworms, including free living planarians and parasitic flukes. Using these animals, we seek to understand quantitatively the fundamental rules that control stem cell collective behavior to optimize tissue regeneration, remolding, and adaptation.

Joanna Wysocka
Professor of Chemical and Systems Biology and of Developmental Biology
Current Research and Scholarly Interests The precise and robust regulation of gene expression is a cornerstone for complex biological life. Research in our laboratory is focused on understanding how regulatory information encoded by the genome is integrated with the transcriptional machinery and chromatin context to allow for emergence of form and function during human embryogenesis and evolution, and how perturbations in this process lead to disease.
