PHD PROGRAM RESEARCH INTEREST |
Our laboratory is focusing on developing and applying solution-state NMR methods, together with computational and biochemical approaches, to understand the molecular basis of nucleic acid functions that range from enzymatic catalysis to gene regulation. In particular, we aim to visualize, with atomic resolution, the entire dynamic processes of ribozyme catalysis, riboswitch-based gene regulation, and co-transciptional folding of mRNA. The principles deduced from these studies will provide atomic basis for rational manipulation of RNA catalysis and folding, and for de novo design of small molecules that target specific RNA signals. Research program in the laboratory provides diverse training opportunities in areas of spectroscopy, biophysics, structural biology, computational modeling, and biochemistry. |

Our research focuses on the discovery and design of new gene-encoded bioactive small molecules from bacteria. We are interested in understanding enzymes involved in their biosynthesis, their therapeutic mechanisms of action, and implications in health and diseases, in particular with respect to the human microbiome. This work is driven by intensive development of new metabolomics and genomics technologies. We subsequently manipulate and engineer these biosynthetic pathways to make new and improved molecules as potential therapeutics such as antibiotics. |

My research philosophy is summed up by a quote from Nobelist Albert Szent-Gyorgyi: “Discovery is to see what everybody has seen and to think what nobody has thought.” My lab studies the molecular and physical mechanisms of cell shape change during cytokinesis and tissue biogenesis during development. Specifically, we are defining how cells ensure proper alignment and sliding of cytoskeletal filaments, and determining the shape of the cell throughout division. To do so, we combine developmental biology, cell biology, biochemistry, and quantitative image analysis. |

PHD PROGRAM RESEARCH INTEREST |
Research in the Lockett group focuses on the development of analytical model systems to: i) chemically modify the surface of thin films, and study chemical and biochemical reactions occurring on those surfaces; ii) study drug metabolism in an environment that closely mimics the human liver; iii) measure tumor invasion in an environment that closely mimics human tissue. / / While these problems require techniques found in analytical chemistry, biochemistry, molecular biology, bioengineering, and surface science we are particularly interested in the technologies that allow us to quantitatively measure reactions and analytes. |

PHD PROGRAM RESEARCH INTEREST |
My research program is centered on understanding fundamental aspects of cell division. During cell division, complex DNA-protein interactions transform diffuse interphase chromatin into discrete mitotic chromosomes, condensing them several thousand fold to facilitate spatial segregation of sister chromatids. Concomitantly, kinetochores form specifically at centromere regions of chromosomes and regulate force-producing interactions with microtubules. While these processes are absolutely required for genomic stability, the in vivo mechanisms of chromosome and kinetochore assembly remain unsolved problems in biology. I investigate 1) the spatiotemporal regulation of mitotic chromosome assembly, and 2) the molecular basis of centromere specification. To do so, I will combine biochemical approaches with high-resolution light microscopy of live cells, whole organisms, and in vitro systems. |

How do networks of cells synchronize behaviors across differing spatial and temporal scales? This fundamental aspect of cellular dynamics is broadly relevant to understanding many biological systems in which the coherence of electrical or chemical signals is required for multicellular patterning or organ function. Our group’s primary research interests are related to understanding the cellular and microenvironmental conditions that are required to support the biorhythmic behavior of the system of cells that natively control heart rate, cardiac pacemaker cells. We utilize a variety of techniques including computational modeling, next generation sequencing, in vivo genetic manipulation, super-resolution imaging, and direct physiological recording to investigate the developmental processes that assemble the hearts pacemaking complex. The ultimate goals of these studies is to determine how the pacemaker cell lineage is patterned in the embryo, build strategies towards fabricating this cell type for therapeutic purposes, and identify vulnerabilities that may lead to pacemaker cell pathologies in humans. |
