ESE Seminar: “New Designer Materials: Sculpting Electromagnetic Fields on the Atomic Scale”

New optical nanomaterials hold the potential for breakthroughs in a wide range of areas from ultrafast optoelectronics such as modulators, light sources and hyperspectral detectors, to efficient upconversion for energy applications, bio-sensing and quantum information science. An exciting opportunity to realize such new nanomaterials lies in controlling the local electromagnetic environment on the atomic- and […]

ESE Seminar: “Physics-Driven Sensing and Processing: From Computational Periscopy to Particle Beam Microscopy”

In many areas of science and engineering, novel signal acquisition methods allow unprecedented access to physical measurements. From digital cameras to microscopes and nano-scale biosensors, the data generated are shaped by both the underlying physics of the phenomena and characteristics of the acquisition device. Meanwhile, in many practical scenarios, the useful signals are remarkably weak, […]

ESE Seminar: “Hybrid Quantum Networks: Interfacing Photons, Phonons, and Superconducting Qubits”

Quantum information science strives to utilize the fundamental laws of physics to achieve revolutionary improvement in computation, communication, and sensing. Existing quantum protocols rely on a wide variety of physical platforms for storing, transferring, and processing of quantum information. Optical photons are the ideal carriers of information because of their low loss, large bandwidth of […]

ESE seminar: “Engineering the Quantum Vacuum”

The vacuum of space may seem empty and boring; however, this void is actually teeming with activity. According to the laws of quantum mechanics, fluctuations of electromagnetic fields are omnipresent even in empty space. These fluctuations can manifest themselves in a variety of ways, including the generation of nanoscale forces between objects—a phenomenon known as […]

ESE Seminar: “Local Geometric Spectral Data Analysis”

Modern technological developments have enabled the acquisition and storage of increasingly large-scale, high-resolution, and high-dimensional data in many fields. Yet in domains such as biomedical data, the complexity of these datasets and the unavailability of ground truth pose significant challenges for data analysis and modeling. In this talk, I present new unsupervised geometric approaches for […]

ESE Seminar: “Liquid Silicon: A New Computing Paradigm Enabled by Monolithic 3D Cross-Point Memory”

Almost every subfield of electrical engineering and computer science are undergoing disruptive times. With Moore’s Law coming to an end, an expanded roadmap for semiconductors beyond traditional CMOS scaling becomes unclear. At the other end, traditional application software development is being replaced by emerging machine learning techniques whose success will, in turn, rely on the […]

ESE Seminar: “Hardware Acceleration in the World of Emerging Applications”

Abstract: Semiconductor technology scaling coming to a screeching halt, coupled with the explosion of data in almost every facet of our lives, makes processing large volumes of data efficiently a critical problem to solve. In this talk, I will highlight three main challenges in designing accelerators and demonstrate that domain-specific hardware acceleration and specialization can […]

The Jack Keil Wolf Lecture in Electrical and Systems Engineering: “The Invention of High Efficient Blue LEDs and Future Solid State Lighting”

ESE Seminar: “Efficient Mid-Infrared Photodetection Using Graphene Plasmons at Room Temperature”

In the history of materials development, many classic materials (Si, III-Vs, organics, etc.) which can be produced reliably at large scale eventually have found critical applications after decades of intensive research, leveraging their distinctive properties. For example, silicon dominates the field-effect-transistor technology because perfect dielectric-silicon interface can be readily realized. Organic materials are currently widely […]

ESE Seminar: “Towards a Seamless Integration of Drones in Smart Cities: Communications and Security”

The use of unmanned aerial vehicles (UAVs), popularly known as drones, will be an integral component of emerging smart city applications ranging from delivery of goods to flying taxis. However, a seamless deployment of such drone-based applications requires addressing technical challenges across communications, security, autonomy, and control. In this talk, we focus on the wireless […]
