My laboratory takes a novel and innovative approach to studying colorectal cancer by leveraging sophisticated genetic tools and practical advantages of Drosophila. We build, study and drug-screen Drosophila cancer models that reflect the complexity and diversity of sequenced human tumors.

Our laboratory uses biophysical techniques including quantitative live-cell imaging, single virus tracking, and correlative cryo-Electron Tomography approaches to gain mechanistic and structural insights into virus-host interactions. Specifically, we are interested in understanding the cell-biology underlying the disassembly and transport of single virus particles such as HIV-1 to their replication centers inside the nucleus
Dynamic changes in chromatin and chromosome architecture regulates patterns of cellular gene expression during differentiation and development, or in response to environmental signals. Our research looks at various levels of chromatin, chromosome and nuclear structure, from individual nucleosome modifications to the dynamic 3D structure of chromosomes and their inter-relationships in the nucleus and how they affect genome functions.
I study the symbiotic interaction of nitrogen-fixing rhizobial bacteria with legume host plants: 1)How bacteria manipulate their environment during host plant invasion such that the plant not only permits entry, but provides an invasion pathway for them; 2)Why the interactions of specific strains of Sinorhizobium with particular Medicago truncatula plant ecotypes are more productive than others; 3)How plants direct resources to productive symbionts at the expense of unproductive ones (cheaters).
Biological membranes; cell-substrate interactions; bionanotechnology.
We are interested in the molecular and cellular mechanisms through which sleep and the circadian clock affect neural plasticity from drug tolerance to long-term memory. We use Drosophila melanogaster and mice for our research with sleep deprivation.
Epigenetic gene regulation in maize.
Molecular and statistical properties of adaptive evolution.
Research in the Stagg lab is directed towards two tracks: the mechanisms of membrane trafficking, and high-throughput high-resolution cryo-EM. On the biological side, we determine the structure and mechanisms of protein complexes involved in vesicle trafficking pathways. We have determined structures of COPII and clathrin coats as well as other membrane remodeling complexes. On the technical side, we develop experimental and computational methods to improve structure determination by cryo-EM.
