CAREER: Reinventing Network-on-Chips of GPU-Accelerated Systems

Description: Research seeking to reinvent on-chip networks for GPU-accelerated systems to remove a communication bottleneck. A major outcome of the project is a set of techniques that enable the development of effective and efficient network-on-chip architectures. Graphics processing units (GPUs) have rapidly evolved to become high-performance accelerators for data-parallel computing. To fully take advantage of the computing power of GPUs, on-chip networks need to provide timely data movement to satisfy the requests of data by the processing cores. Currently, there exists a big gap between the fast-growing processing power of the GPU processing cores and the slow-increasing on-chip network bandwidth. Because of this, GPU-accelerated systems are interconnect-dominated and the on-chip network becomes their performance bottleneck.

Developing a Biomanufacturing Platform for the Site-Selective Functionalization and Structural Diversification of Cytochalasan-Based Carbon Skeletons

Description: This project will identify fungal enzymes that efficiently modify more than one substrate in a predictable way. Also, enzymes will be engineered to expand the range of substrates. A biomanufacturing platform to synthesize bioactive molecules at lower costs will be the end result. Fungi can synthesize small molecules with complex structures using a number of highly coordinated enzymes. These molecules are difficult to make synthetically, and they can aid in crop production or have beneficial human health effects. Cytochalasans are phytotoxic, cytotoxic and actin-binding natural products. Produced by fungi, over 400 variants have been described. The structural diversity is partly explained by the flexibility of the enzymes that introduce and modify functional groups. These enzymes structurally rearrange the core carbon skeleton in a site-selective manner, often on more than one substrate. Genome mining will be used to identify cytochalasan tailoring enzymes. Overproducing strains will be characterized chemically. Transcription factor over-expression will be investigated. Targeted gene knock-out will confirm the function and scope of the enzymes. The enzymes will be engineered to expand their substrate range. Synthetic biology and metabolic engineering tools will be used to generate a biomanufacturing platform for large scale production and functionalization of cytochalasan-based carbon skeletons. This project will generate fundamental knowledge on how to effectively engineer enzymes and metabolic pathways for efficient and rapid structural diversification of bioactive molecules with commercial potential.

Collaborating on Scholarship: Best Practices for Team Research Projects

Description: Article on collaborating on scholarship. Collaborating on scholarship has the potential to provide many advantages, including benefiting from others’ expertise, reinforcing accountability, and providing motivation. However, working with others is tricky—consider compatible work habits, receptivity to criticism, and commitment to fulfill responsibilities. Decisions to be made include where to publish, in what order authors’ names will appear, and how the manuscripts will be written. Who will coordinate? Who will write what? Who will revise? Also, consider how to address problems—missed deadlines, less-than-stellar quality, how to say “no” in the future, and more. This version is the authors' manuscript.

Functional Porous Organic Polymers as Advanced Decontamination Materials for Water Purification

Description: This project seeks to develop and deploy a new class of porous organic polymers which have high capacity and selectivity to rapidly remove heavy metal contaminants well below parts per million level standards set by the Environmental Protection Agency. The project will engineer porosity and surface chemistry of porous organic polymers to clean inorganic heavy metal contaminants from both surface water and wastewater. Porous organic polymers are robust, chemically and thermally stable, scalable, and modular, with very high surface area. The modularity of these polymers allows for a molecular-level tuning of the pore structure and surface chemistry that allows for engineered site-specificity of binding sites that target the heavy metal contaminants. Recent data shows these new materials offer a significant increase in capacity relative to benchmark materials, with a rapid removal of mercury and other heavy metal ions. This project will advance the concept by exploring rational design of these porous polymers with different topologies by customizing the monomer with various binding groups. The objectives of the project include design, synthesis, and characterization, followed by assessment of these materials to remove inorganic contaminants from water, and thirdly, development of materials with multiple recognition sites for removal of complex inorganic contaminants. The work will impact wastewater treatment, including municipal water, as well as the nuclear, fracking, and mining industries.

NSFDEB-NERC: Collaborative Research: Wildlife corridors: do they work and who benefits?

Description: This study will use large corridors and habitat patches that have been stable for 50-200 years, so that genetic patterns reflect the influence of landscape pattern. Each landscape contains a corridor connecting two natural patches and two types of reference conditions, namely two patches lacking a connection that are about the same size and interpatch distance as the connected patches, and an intact natural area containing two sampling locales with similar size and spacing. The study will use 20 independent landscapes to quantify how corridor traits affect gene flow, and will use non-flying mammals as focal species because they are strongly affected by fragmentation. The research team hypothesizes (1) a strong non-linear decline in success (gene flow) with corridor length, reflecting the skewed distribution of dispersal distances within species; (2) success will drop steeply as corridor width falls below a threshold, with the threshold determined by species traits; and (3) species that are bigger, are habitat specialists, or have greater dispersal abilities (relative to brain size or reproductive rate) will benefit more from corridors. Testing these hypotheses will allow generalization to a wide range of mammal species not included in this project. We will use highly flexible Random Forest models to answer the overarching question: What landscape traits (e.g., corridor width, degree of human disturbance) and species traits (mobility, affinity to particular land cover types) are associated with effective corridors?

Cross-Language Comparison of Mismatched Annotation in Interlinear-Glossed Texts

Description: This presentation explores the variation in interlinear-glossed text (IGT) in 5 closely related South-Central Tibeto-Burman languages with verb stem alternation, reduplicated adverbial modifiers, and pre-verbal directionals. While IGT is a rich representation of language, IGT for even closely related languages can look markedly different due to individual linguists’ divergent analyses. In comparing the discrepancies between representations of such features, we gain insight into the underlying analytic thinking of the annotator to reexamine and improve analyses.

Adult Attachment, Perceived Social Support, and Problematic Video Gaming Behavior

Description: With the growing popularity in video games, there has been increased concerns over the prolonged exposure to the entertainment medium. Problematic gaming is defined as a pattern of gaming behavior that causes significant impairment in personal, social, other important areas of functioning, often characterized by preoccupation and loss of interest in other areas. This study examined how problematic gaming behaviors may be influenced by insecure adult attachment and perceived social support from differing sources. It was hypothesized that avoidant attachment would have a significant direct and indirect effect (via perceived social support) on problematic gaming. In addition, perceived social support from online friends and from offline friends were hypothesized to moderate the relationship between attachment and problematic gaming, Participants were recruited from both SONA (n = 151) and Amazon's Mturk (n = 264) to complete an online research questionnaire that measured variables of interest. Results indicated that the direct and indirect effects of attachment avoidance on problematic gaming were supported in both subsamples but the moderator effects were not. Further exploratory analysis found that anxious attachment demonstrated a similar pattern as avoidant attachment, but with a significant moderator effect of perceived social support from online friends (enhance) on the attachment anxiety and problematic gaming relation. Additionally, anhedonia and depressive symptoms were found to be significantly correlated with problematic gaming. Limitations, future research directions, and clinical implications are discussed.

Alexandria Ocasio-Cortez: Media Coverage of Age, Gender, and Ethnicity in the 116th Congress

Description: This study focuses on Alexandria Ocasio-Cortez, the U.S. Representative for New York's 14th Congressional District, and how news media portray her based on her gender, age, and ethnicity, which still play essential roles in the political system in the United States. The analysis of previous academic research, newspaper articles from the New York Times and the Washington Post (June 1, 2018 to June 30, 2019) and framing and feminist theories are used to evaluate coverage of Alexandria Ocasio-Cortez. The newspaper stories are examined based on the framing of traits including being the youngest woman ever elected to Congress, being Latina, and being one the most progressive politicians in the Congress. The main objective of this study is to shed light on a topic that at this moment in time is more relevant than ever because the 116th Congress has the highest number of women and women of color in U.S. history. I examine media coverage that Rep. Alexandria Ocasio-Cortez receives for stereotypical frames, so that, overall, all women running or holding public office may receive unbiased and more balanced media coverage. This study also intends to hold media outlets accountable for the way they portray different candidates because it has a significant influence on the voting population.

Analysis of the Cytochrome P450 and the UDP-Glucuronosyltransferases Families and Vitamin D3 Supplementation in Anoxia Survival in Caenorhabditis elegans

Description: Alteration in diet and knockdown of detoxification genes impacts the response of C. elegans to oxygen deprivation stress. I hypothesized that feeding worms a vitamin D3-supplementation diet would result in differential oxygen deprivation stress response. We used a combination of wet lab and transcriptomics approach to investigate the effect of a vitamin-D3 supplemented diet on the global gene expression changes and the anoxia response phenotype of C. elegans (Chapter 2). C. elegans genome consists of 143 detoxification genes (cyp and ugt). The presence of a significant number of genes in these detoxification families was a challenge with identifying and selecting specific cyp and ugt genes for detailed analysis. Our goal was to understand the evolution, phylogenetic, and expression of the detoxification enzymes CYPs and UGTs in C. elegans (Chapter 3). We undertook a phylogenetic and bioinformatics approach to analyze the C. elegans, detoxification family. Phylogenetic analysis provided insight into the association of the human and C. elegans xenobiotic/endobiotic detoxification system. Protein coding genes in C. elegans have been predicted to be human orthologs. The results of this work demonstrate the role of C. elegans in the identification and characterization of vitamin D3 induced alterations in gene expression profile and anoxia response phenotypes and the identification of human orthologs for the detoxification enzymes and provides insight into the gene expression pattern.
