The BMSE program encompasses a wide variety of research within the broad areas of molecular genetics and molecular biology. Specific areas of research include : (1) the ecology , regulation, and systems biology of diseases and symbioses caused by viruses, bacteria, and fungi in plants and animals and (2) understanding developmental processes, regulatory networks, ion channels, microtubules, neural plasticity, and stem cell biology in invertebrates such as nematodes and vertebrates including marine chordates and mammals.
Roles of metals in metalloenzymes; microbial iron acquisition, including siderophores and new metallo-enzymes.
Biochemistry; protein structure and function relationships; protein dynamics; chemotaxis in bacteria.
The role of radicals in enzyme catalysis and degradation, development of electron bifurcating flavoproteins, and biogeochemical redox cycling of phosphorus.
Basic mechanisms and disorders of neural plasticity; the role of microRNAs in stem cell differentiation.
Combining theory and experimentation to understand how navigational decisions come about in terms of neural-circuit computation.
Cellular communication between bacteria, including mechanisms and biology of contact-dependent growth inhibition; epigenetic gene regulatory mechanisms.
Microbial pathogenesis; innate and adaptive immune responses to infection; coagulopathy and inflammation of sepsis; vaccine development.
Macrophages patrol our tissues looking for signs of injury or infection. The Morrissey Lab wants to understand how macrophages measure, add and subtract all the signals they receive to calculate their response to a target. We use high resolution live imaging, synthetic biology and biochemistry to figure out when and where signaling molecules are activated to make these essential decisions. We are motivated by re-wiring macrophage signaling pathways to generate new cancer immunotherapies.
