    Title: Regulation of lipid droplets during immune response in C. elegans after E. faecalis infection
    For centuries, the common man notion is that fat is bad for health. But, scientists have recently discovered growing evidence that fat cells have a protective role during bacterial infection in mammals, and in wound healing process in fruit flies. In the present study, for the first time, we aim to dissect the role of lipid droplets during immune response in C. elegans,after infection with Gram-positive bacterium, Enterococcus faecalis. Our preliminary studies strongly suggest that lipid droplets are mobilized immediately after infection, and can help in eliciting immune response.Our long-term goal is to better understand the gene regulatory networks that link lipid homeostasis to host defensesin infection.In all, our findings can be further studied in humans to better understand the role of fat during host defense mechanisms, and can eventually help to identify novel therapeutics based on fat homeostasis.

    Title: Action dynamics in cell invasion and migration during C. elegans development
    Analyzed actin dynamics during a developmental event, Anchor Cell (AC) invasion in C. elegans through transgenesis, RNAi, cloning, and microscopy techniques. Specifically, studied the role of actin nucleator protein Arp 2/3, and its upstream regulators Wiskott–Aldrich syndrome protein (WASP) and WASP-family verprolin-homologous protein (WAVE), during invadopodia formation from AC and subsequent breaching of Basement Membrane (BM) that bridges neighboring vulva cells. The findings from this study will help to better understand cell invasion during cancer metastasis due to the conserved role of actin regulators in nematodes and humans.

    Title: Imaging retrogradely transported vesicles through I-switch in C. elegans
    This work is part of a collaborative effortthat aims to develop a method to exclusively track retrogradely moving synaptic vesicle proteins during neuronal transport by specialized DNA nanomachine, I-switch. For this purpose, I analyzed expression pattern of transgenic lines containing psnb-1::SNB-1::9E, which assist in binding I-switch (SNB-1: Synaptobrevin-1).  Furthermore, validated the functionality of these transgene to rescue snb-1 hypomorhic and null mutant phenotypes.

    Title: Role of EGL-26 during vulva organogenesis
    The LRAT (Lecithin Retinol Acyl Transferase) family protein, EGL-26 controls vulva morphogenesis through maintaining VulF derived dorsal lumen. With an aim to dissect the mechanistic role of EGL-26, I analyzed actin organization in VulF lumen in wtand egl-26 mutants throughlifeAct::GFPreporter. Abnormal actin organization within VulF was seen in egl-26 mutants, suggesting a cross talk between EGL-26 and cytoskeleton during vulva lumen formation. I also dissected egl-26 promoter for cis-regulatory elements and TF binding sites through bioinformatics tool, LASAGNA.Title: Rotational manipulation of worms through acoustic waves.
    In a collaborative effort with Penn State bioengineering department, I established ARM (Acoustic Rotational Manipulation) method to precisely rotate C. elegans in microfluidic devices. This method helped to investigate neuronal pattering of ALA dendrites and reproductive pathologies in worms.

    Title: Modulation of C. elegans vulva organogenesis by nuclear hormone receptor NHR-25
    During my Ph.D I analyzed the role of conserved nuclear hormone receptor NHR-25 during vulva formation in C. elegans through genetic, cellular, and molecular techniques. Graded expression of NHR-25 was seen during vulva cell fate specifications and migrations. In vitro and in vivo sumoylation assays identified that a proper ratio of sumoylated to un-sumoylated NHR-25 specifies 30 cell fates. In addition, nhr-25(RNAi) and nhr-25(ku217) studies identified a pivotal role for NHR-25 during vulva cell migrations, fusions and morphogenesis. Altered gene expression pattern of EGF/LIN-3 and HOX/LIN-39 were seen in nhr-25(lf)within vulva. Observed genetic interaction with smp-1/plx-1 pathway and nhr-25 during collective vulva cell migrations.

    Title: Genetic analysis of pry-1/axin in Caenorhabditis briggsae
    During the study I aimed to analyze and compare the role of pry-1/Axin during vulva development in C. elegans and C. briggsae. Quantified vulva phenotypes in Cbr-pry-1 through vulva cell fate marker expression, inductions and lineage analysis. Carried out genetic interaction of cbr-pry-1 with canonical Wnt signaling components, cbr-bar-1cbr-pop-1 and Hox cbr-lin-39. Further comparative analysis with Ce-pry-1 identified novel role of Wnt signaling in specifying of 20 cell fates.
