Past Experience

As a young scientist I have had the incredible opportunity to travel the world, contributing to research projects in beautiful places with fantastic mentors. From established institution such as the Marine Biological Laboratory in Woods Hole to newer science and technology centers, such as The Center for Microbial Oceanography: Research and Education I have been exposed highest quality research opportunities. My adventures have also taken me to a little island in the middle of the Atlantic Ocean and the Bermuda Institute of Ocean Sciences. During my time in Hawai’i I was an EDEN (Evo-Devo-Eco-Network) Grant Recipient performing research at the Kewalo Marine Laboratory.

After my undergraduate degree I was a Research Lab Technician in the Crump Lab at The Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research at USC.

The Crump Lab is interested in how genetic information is decoded to generate the precise three-dimensional shapes of organs. As a model, we study the facial cartilages and bones of the larval zebrafish, which can be continuously imaged over time in living transgenic embryos. Specific research topics include the developmental origins of the neural crest progenitor cells that build the craniofacial skeleton. As an example, the pharyngeal arches, where the neural crest cells arise (to right in green), transform into the adult facial skeleton (to the right in blue).

My work in the lab focused on screening a large number of novel candidate genes whose expression is highly enriched in a population of cells known as the early neural crest.

The Synergistic Nature of the Behaviors and Mechanisms that Support Effective Burrowing in the Mantis Shrimp Squilla empusa.

Mentor: Dr. Kristina Mead-Vetter

The mantis shrimp Squilla empusa is a charismatic marine crustacean known for its powerful strike, keen sense of vision, and chemosensory abilities. These benthic creatures create extensive burrows that are important in feeding, reproduction, and protection from predation. Through field observations of a population located in Great Harbor in Woods Hole, MA this species of mantis shrimp has been observed to construct burrows faster and makes more alterations than previously recorded. To understand the mechanics of these burrowing behaviors, mantis shrimp were filmed making burrows in the lab using high-speed videography. S. empusa used two markedly distinct methods of burrowing: pleopod fanning and maxilliped bulldozing. Through this series of observations and analyses we are starting to understand how pleopod anatomy and kinematics work synergistically to create an effective burrowing system.

Project: Understanding mechanisms of toxin production via transcriptome analysis of ciguatera-causing Gambierdiscus spp.

This work used the Illumina platform and microarrays to probe the transcriptome of Gambierdiscus spp, a dinoflagellate that grows in Hawaiian coastal waters. Because the transcriptome of an organism reflects the genes that are actively being expressed at any given time, the proposed work, by elucidating levels of messenger RNA expression in the target organisms, is expected to provide valuable insights into the mechanisms responsible for toxin production, responses to stress and/or subsequent inactivation of pathogenic induction. Knowledge of the mechanisms associated with gambiertoxin production will enhance understanding of the relationship between environmental conditions and outbreaks of ciguatera fish poisoning (CFP). This will lead to more informed risk management and ultimately to the reduction of CFP. Such understanding is vital to advancing the field of risk management with respect to recreational water use and seafood consumption beyond reliance on empirical correlations and towards policies that are based on a mechanistic understanding of the threats these organisms pose to human health.

Project: Molecular Profile of Stem Cells in Sea Urchin Tissues.

This project investigated the temporal and spatial expression of a panel of stem cell genes in embryos and adult tissues of sea urchins. These studies will involve both quantitative reverse transcriptase PCR and RNA in situ hybridization.The ultimate goal of this research is to begin to understand the role that stem cells play in tissue maintenance and regeneration and how this impacts the life histories of these animals.

Project: Transcriptomes of Pre-competent, Competent, and Metamorphosed Larvae of Hydrodies elegans Reveal the Distinct Role of Innate Immunity Genes in Response to a Bacterial Settlement Cue.

Hydroides elegans is a common serpulid polychaete, which like all invertebrates, lacks an antibody-based adaptive immunity. Invertebrates have evolved efficient defense responses to pathogens as well as sophisticated systems for recognizing and differentiating beneficial and pathogenic microorganisms. An important factor associated with invertebrate innate immunity, are microorganism-associated molecular patterns (MAMPs), which can initiate signaling cascades by first interacting with pattern recognition receptors (PRRs) such as Toll-like receptors (TLRs) and peptidoglycan recognition proteins (PGRPs). Both MAMP-mediated signaling can initiate signaling cascades, usually through the nuclear factor-κB (NF-κB) or similar pathway, that lead to the activation of a variety of immune responses. The concept of an immune response to MAMPs is particularly relevant for H. elegans larvae, which are induced to settle and rapidly metamorphose by the presence of a well-developed bacterial biofilm. The ultimate goal of this work is to elucidate the importance of differentially expressed innate immunity genes. This will enhance our understanding of the role of these genes in responding to cues from marine bacteria, as well as identifying gene function and pathways in the metamorphosis.
