research overview

  • With the emergence of public cloud computing and the internet of things, modern computer architectures are inadequate to address the security and privacy concerns of users. In this work, we look for innovative solutions to secure the computer from the hardware up. By designing the computer architecture with security as a number one priority, along with performance, we can provide additional guarantees about the security and privacy of data. In addition we look to reinforce the public' resilience to polluted information considering that social media has now taken on a new role with respect to democracy around the world.

courses taught

  • ECEN 3593 - Computer Organization
    Primary Instructor - Fall 2020
    Studies computer design at the gate level. Discusses instruction set architecture design, arithmetic and logic unit design, control logic, memory design and caches, simple pipelining, I/O and peripheral devices. Briefly covers aspects of modern computer architecture, such as multicore processors and cache coherence for these. Degree Credit not granted for this course and CSCI 4593. Formerly ECEN 4593.
  • ECEN 5033 - Special Topics
    Primary Instructor - Fall 2019
    Examines a special topic in Electrical, Computer and Energy Engineering. May be repeated up to 9 total credit hours.
  • ECEN 5593 - Advanced Computer Architecture
    Primary Instructor - Spring 2021
    Provides a broad-scope treatment of important concepts in the design and implementation of high-performance computer systems. Discusses important issues in the pipelining of a processor, out-of-order instruction issue and superscalar designs, design of cache memory systems for such systems, and architectural features required for multicore processor designs. Also studies current and historically important computer architectures. Recommended prerequisite: ECEN 4593. Same as CSCI 5593.
