    Abdulaziz, A. (ECE) – Learning-Based Channel Estimation for Next-Generation Wireless Communications

    Engineering 2 Engineering 2 1156 High Street, Santa Cruz, CA
    Hybrid Event

    Coherent wireless reception depends on accurate channel state information (CSI), yet acquiring CSI through pilot transmission consumes time–frequency resources that could otherwise carry data. This tradeoff becomes more pronounced in time-varying and frequency-selective channels and in short-packet communications, where accurate channel estimation is challenging and pilot overhead can be significant. This dissertation investigates how CSI […]

  • Abstract digital illustration featuring gears and interconnected technology elements.

    Valderrama, S. (CSE) – Closing Data Gaps for Cybersecurity AI Training and Evaluation

    Engineering 2 Engineering 2 1156 High Street, Santa Cruz, CA
    Hybrid Event

    Artificial intelligence and machine learning models depend on large and diverse datasets to learn patterns across different situations and generalize to cases they have not seen before. In cybersecurity, suitable data is difficult to find for two main reasons: first, sensitive information limits what organizations can share; second, public datasets often lack the coverage or […]

    Mastoras, M. (BMEB) – Polishing genome assemblies and leveraging their improved quality to study centromere variation

    Physical Sciences Building Physical Sciences Building, Santa Cruz, CA
    Hybrid Event

    A complete and accurate genome reconstruction serves as the foundation for studying an organism’s biology and the mechanisms underlying disease. It is particularly critical for reference genomes, which provide a universal coordinate system for downstream genomic analysis. Errors or missing sequences in a reference genome create bias in all of the studies built on top […]
