Machine learning has been widely adopted to medical imaging research, yet it suffers from domain shift for real world applications. Due to the heterogeneity of medical data, machine learning-based diagnostic models are also prone to biases. In this thesis, we start from arguing the necessity of domain adaptation to achieve the optimal performance for each […]
Graphs are powerful mathematical tools that enable modeling of complex systems. Graph machine learning exploits possibly unknown data structures, which provides a unified approach to tackle a wide variety of problems. However useful in practice, graph machine learning solutions tend to suffer from three main limitations: they do not scale with the size of the […]
This talk will present a brief overview of advances in ferroelectric devices and their integration into computing systems to provide novel functionality and energy efficiency in various data intensive applications. The talk will emphasize on cross-stack design opportunities in designing stacked intelligent 3D memory systems.
I plan to tell two short stories. The first story is about a new drop fluidics that uses a deformable and stretchable elastomeric film as the platform. Such a soft film decorated with magnetic particles can be deformed locally with an external magnetic field. When these deformations are coupled with capillary force, small liquid drops […]
Machinery relies on lubrication to regulate the friction and wear at contacting interfaces. As new lubricants become less viscous to comply with environmental and cost-saving standards, the risk of surface-initiated machine failure grows. We show that metal oxide additives in low-viscosity lubricants will form protective coatings, or tribofilms, in situ at contacting interfaces. Compared to […]

These talks will be held jointly, with each talk 30 minutes each (1 hour total). Talk 1: "Optimizing Anomaly Detection for GenAI based Digital Twins of Wearable Data" (Uma Balakrishnan) In this presentation, we introduce a methodology that utilizes both real and synthetic datasets (digital twins) to address the uncertainties associated with anomaly detection thresholds […]
Abstract: Nanostructured materials with interconnected nanoscale structures have garnered significant attention due to the ability to precisely regulate molecular transport by tuning molecular-level properties and offering more functional interfaces for interactions compared to bulk systems. Through self-assembly, liquid crystal (LC) mesophases offer a route to achieve nanostructured polymers, a promising alternative to traditional nanostructured inorganic […]
