Title: Beyond AI: Societal Opportunities for Future Hardware Design

Abstract: Computing hardware has long been a critical component in the advancement of technology. Most recently, we've witnessed an explosive progression in the capabilities and applications of AI, enabled in large part by AI hardware acceleration. Looking beyond the potential benefits of AI acceleration, what else can future hardware designs contribute to benefit society? In this talk, I'll propose three emerging areas of research that are poised to have a significant impact on our world: hardware enforcement of data privacy, novel system designs to tame and exploit the data flood, and new paradigms of sustainable computing.

Title: Dendrocentric Learning: The Future of Artificial Intelligence

Abstract: Artificial Intelligence (AI) now advances by performing twice as many floating-point multiplications every two months, but the semiconductor industry tiles twice as many multipliers on a chip every two years. Moreover, returns from tiling these multipliers ever more densely now diminish because signals must travel relatively further and further. While travel can be shortened by stacking tiled multipliers in a three-dimensional (3-D) chip, such a solution acutely reduces the available surface area for dissipating heat. Here I propose to transcend this 3-D thermal constraint by moving away from learning with synapses to learning with dendrites. Synaptic inputs are not weighted precisely but rather ordered meticulously along a short stretch of dendrite, termed dendrocentric learning. With the help of a computational model of a dendrite and a conceptual model of a ferroelectric device that emulates it, I illustrate how dendrocentric learning AI—or Synthetic Intelligence (SI) for short—could run not with megawatts in the cloud but rather with watts on a smartphone.

Title: New Frontiers in Terahertz Technology

Abstract: Although unique potentials of terahertz waves for chemical identification, material characterization, biological sensing, and medical imaging have been recognized for quite a while, the relatively poor performance, higher costs, and bulky nature of current terahertz systems continue to impede their deployment in field settings. In this talk, I will describe some of our recent results on developing fundamentally new terahertz electronic/optoelectronic components and imaging/spectrometry architectures to mitigate performance limitations of existing terahertz systems. In specific, I will introduce new designs of high-performance photoconductive terahertz sources that utilize plasmonic nanoantennas to offer terahertz radiation at record-high power levels of several milliwatts – demonstrating more than three orders of magnitude increase compared to the state of the art. I will describe that the unique capabilities of these plasmonic nanoantennas can be further extended to develop terahertz detectors and heterodyne spectrometers with quantum-level detection sensitivities over a broad terahertz bandwidth at room temperatures, which has not been possible through existing technologies. To achieve this significant performance improvement, plasmonic antennas and device architectures are optimized for operation at telecommunication wavelengths, where very high power, narrow linewidth, wavelength tunable, compact and cost-effective optical sources are commercially available. Therefore, our results pave the way to compact and low-cost terahertz sources, detectors, and spectrometers that could offer numerous opportunities for e.g., medical imaging and diagnostics, atmospheric sensing, pharmaceutical quality control, and security screening systems.

Title: From Nonlinear Optics to High-Intensity Laser Physics

Abstract: The laser increased the intensity of light that can be generated by orders of magnitude and thus brought about nonlinear optical interactions with matter. Chirped pulse amplification, also known as CPA, changed the intensity level by a few more orders of magnitude and helped usher in a new type of laser-matter interaction that is referred to as high-intensity laser physics. In this talk, I will discuss the differences between nonlinear optics and high-intensity laser physics. The development of CPA and why short, intense laser pulses can cut transparent material will also be included. I will also discuss future applications.

Bio: Dr. Donna Strickland is a professor in the Department of Physics and Astronomy at the University of Waterloo and is one of the recipients of the Nobel Prize in Physics 2018 for developing chirped pulse amplification with Gérard Mourou, her PhD supervisor at the time.

Title: Srinivasa Ramanujan and Signal Processing

Abstract: The great mathematician Srinivasa Ramanujan introduced a summation in 1918, today called the Ramanujan-sum. For many years this summation was used by mathematicians to prove important results in number theory. In recent years, some researchers have found applications of this sum in digital signal processing, especially in identifying periodic components of signals buried in noise. In our recent work we have generalized the Ramanujan-sum decomposition in several directions, and this has opened up some new theory as well as applications. Many beautiful properties are enjoyed by the new representations, thanks to the genius and vision of Ramanujan. In this lecture we briefly talk about Ramanujan as a person and give an overview of the new signal processing developments. Applications in signal denoising, and in the study of DNA and protein sequences will be presented among others.

Title: Enhancing Learning and Inclusivity in Electrical Engineering

Abstract: How can we educate students to be the most effective engineers when they graduate? What does it take to attract a broader range of students to electrical and computer engineering? What curricular efforts could support both of these goals? These are important questions for the discipline. As part of an NSF-funded Revolutionizing Engineering Departments (RED) grant, “Developing Changemaking Engineers,” the Shiley-Marcos School of Engineering (SMSE) at the University of San Diego (USD) is working to address these questions.

In this talk, I'll begin with a study that explores a large, multi-institutional, longitudinal dataset of engineering undergraduates. I'll describe who is currently attracted to engineering and will highlight how the field of electrical engineering fares compared to other engineering disciplines. Then, I'll describe one promising approach to change the demographics of the electrical engineering student body and to increase the learning that happens in the undergraduate curriculum. The approach entails reframing electrical engineering from a purely technical discipline to one which is socio-technical and I'll present modules we've developed for Circuits that accomplish this.

Title: Google Quantum AI and The University of Massachusetts Amherst

Abstract: Over the past decade, the field of quantum computing has evolved from one primarily known for generating scientific papers to one which promises to enable computations that would not be possible using any other known technology. Following this potential, numerous large companies are racing to build a quantum computer, and governments across the globe are pouring money into academic research that may lead to the improvement of the fundamental building blocks and supporting technologies used throughout the quantum information sciences. Much of the excitement is driven by seemingly exponential progress in the field and the associated steady stream of major announcements, which have quickly grown from basic proof of principles to large system demonstrations. In fact, many of the major industrial players in the field who have helped to drive this progress currently have their eyes set on the realization of large-scale error-corrected quantum computers. Behind the rapid progress, is a story of complex system design and numerous engineering innovations.

In this talk, I will give an overview of superconducting quantum computing, with a focus on research topics of interest to the electrical engineering community. The talk will begin with a brief introduction to the field of quantum computing. I will then describe the technology at the core of Google’s state-of-the-art Sycamore quantum computer systems before explaining how these devices have been used for the first demonstrations of quantum advantage and error suppression using quantum error correction. After bringing the audience up to date with the state-of-the-art, I will describe the significant gap between today’s technology and that required for useful error-corrected quantum computing and how EE-related technologies such as integrated circuits (ICs), packaging, and interconnects will be critical in bridging this gap. Examples of research ICs will be presented. The talk will conclude with a brief discussion of open issues related to the scaling of superconducting quantum computers.

Title: Economic Optimization of Large-Scale Systems with Model Predictive Control

Abstract: Maintaining high standards of living while decreasing our impact on the planet requires both new technologies as well as increasingly efficient operation of
these technologies at large scale. This talk presents the central ideas of model predictive control, which has become over the last 20 years the leading advanced feedback control method, both in industrial practice as well as a topic of control theory research. We discuss the fundamental reasons for this success, which builds upon the foundations of optimal control and dynamic modeling, supplemented with measurement feedback to make the resulting system robust against model inaccuracies and disturbances. We present a large scale example of such a system performing in real time an economic optimization of a 155 building campus-wide energy system.

Next we discuss the education of engineers to understand, operate and improve this kind of technology. We start with a motivational example that can be easily understood by any undergraduate engineering student. Although conceptually simple, the fundamental ideas of noisy measurements, unstable processes, Brownian motion, feedback stabilization, controller tuning, and integral control already play central roles in understanding the complex behavior that arises. The talk closes with two examples of recent experimental hardware advances that enable a rethinking of the control laboratory as a vehicle for both teaching and demonstrating new research results in feedback control theory.
