Talk Title: Micro- and Nanofluidic Systems for Molecular Biosensing, Nanotoxicity, and Optogenetics
Series: Semiconductors & Microelectronics Technology
Abstract: Micro- and nanofluidic systems, in conjunction with biochemistry, microscopy, nanomaterials, and machine learning components, serve as potent tools with a wide array of applications in the biomedical field. These applications encompass crucial areas like molecular diagnosis, biophysics, and optogenetics. In this presentation, we shed light on an innovative pneumatic-controlled nano-sieve device. This device is packed with magnetic beads and facilitates the rapid concentration of drug-resistant bacteria from blood samples. Subsequently, an isothermal amplification and CRISPR assay are conducted. This system achieves an on-chip concentration factor of 20x, effectively pushing the bacterial detection threshold to 100 cfu/mL. To make sensing automatic and devoid of the need for specialized instruments, a computer vision program is developed. This program exhibits an approximate accuracy rate of 100% in discerning both positive and negative samples within the microfluidic chip. This attribute renders it particularly suitable for on-site detection in resource-limited environments. Furthermore, we delve into our recent strides in comprehending the interactions between nanomaterials and eukaryotic organisms. This understanding is facilitated by a deformable microfluidic platform, advanced microscopy, and molecular dynamic simulations. Within this context, we explore a range of clinical applications. These applications span from in vivo bioimaging employing optofluidics to addressing dentine hypersensitivity and advancing the realm of synthetic biology.

Talk Title: Quantum Entangled Interferometers and Their Applications
Series: Quantum Science & Technology Seminar Series
Abstract: A new type of quantum interferometer utilizes nonlinear parametric processes as the wave splitting and recombination elements. Because of the nonlinear interaction, the fields inside the interferometer are intrinsically entangled and quantum mechanically correlated. This type of quantum correlated interferometer exhibits some unique properties that we will review in this talk. Because of these properties, this type of interferometer is superior to traditional beam splitter-based interferometers in many aspects. We will present its various forms and its realizations with different types of waves such as microwave, atomic waves (both internal and external degrees), and sound waves. We will discuss its applications in quantum metrology, quantum imaging, quantum spectroscopy, and quantum state engineering.
Biography: Professor Ou obtained his BS in 1984 from Peking University and his Ph.D. in 1990 from University of Rochester. He is now a chair professor in City University of Hong Kong. Professor Ou is an expert in quantum optics, especially in quantum interference, for which he is famous for the Hong-Ou-Mandel interferometer. His current research focuses on quantum metrology, quantum sensing, quantum state engineering, and the fundamental quantum interference effects. Professor Ou is a fellow of American Physical Society and of Optica (formerly Optical Society of America).

Talk Title: Unleashing the Power of Nano-Mechanics on Chip using CMOS-based Ferroelectric Hafnia
Series: Semiconductors & Microelectronics Technology
Abstract: The incorporation of nanoscale piezoelectric transducers into advanced semiconductor nodes enables the direct implementation of high-frequency nanomechanical resonators onto CMOS chips. The discovery of metastable ferroelectric phase in hafnia heralds the long-awaited arrival of this integrated piezoelectric transducer. Hafnia films, already utilized in amorphous form as high-k dielectrics in standard semiconductor processes, can be further engineered to stabilize in the ferroelectric phase with significant piezoelectric coupling. Hafnia piezoelectric transducers pave the way for the development of on-chip nanomechanical resonators with quality factors several orders of magnitude higher than solid-state counterparts. This exceptional performance, combined with seamless integration with electronic circuitry, enables the creation of on-chip clocks, local oscillators, and microwave filters, meeting the escalating frequency-control requirements in computing and communication applications. This presentation will provide an overview of Tabrizian Lab's work focusing on the development of nanoscale hafnia transducers and resonators, and their application in creating on-chip distributed clocks for massive computing and monolithic microwave spectral processors for adaptive wireless communication.

Talk Title: What Do Pre-Trained Speech Representation Models Know?
Abstract: Pre-trained speech representation models have become ubiquitous in speech processing over the past few years. They have both improved the state of the art and made it feasible to learn task-specific models with very little labeled data. However, it is not well understood what linguistic information is encoded in pre-trained models, where in the models it is encoded, and how best to apply this information to downstream tasks. In this talk I will describe recent work that begins to build an understanding of pre-trained speech models, through both layer-wise analysis and benchmarking on tasks. We consider a number of popular pre-trained models and investigate the extent to which they encode spectral, phonetic, and word-level information. The results of these analyses also suggest some ways to improve or simplify the application of pre-trained models for downstream tasks. Finally, I will describe our efforts to benchmark model performance on a variety of spoken language understanding tasks, in order to broaden our understanding of the semantic capabilities of speech models.

She has served as a program chair/co-chair for ICLR, Interspeech, and ASRU, and is an Associate Editor for TACL and IEEE T-PAMI. Her group's work spans a variety of topics in spoken, written, and signed language processing, with a particular interest in representation learning, cross-modality learning, and low-resource settings.
