Most of us think of electricity as a clean and reliable source of energy, which flows out of the plug whenever we need it. The reality is far more complex. The reliability of our electricity supply is increasingly threatened by extreme weather, causing more frequent power outages. The cleanliness of our electricity supply varies greatly […]
Abstract: Despite efforts to align large language models (LLMs) with human intentions, popular LLMs such as chatGPT, Llama, Claude, and Gemini are susceptible to jailbreaking attacks, wherein an adversary fools a targeted LLM into generating objectionable content. For this reason, interest has grown in improving the robustness of LLMs against such attacks. In this talk, we review the current state of […]
This will be a hybrid event with in-person attendance in Levine 307 and virtual attendance on Zoom. ABSTRACT Locomotion in complex environments (e.g., rubble, leaf litter, granular media) is essential to mobile engineered systems such as robots. Effective locomotion requires complex control strategies to interact with terrain heterogeneity. Computational intelligence (CI), which typically includes rapid […]
Bio & Abstract: Jennifer Cochran is the Macovski Professor of Bioengineering and Senior Associate Vice Provost for Research at Stanford University. Prof. Cochran was recruited in 2005 as one of the founding faculty members in Stanford’s Bioengineering department and served as its Chair from 2017-2022. She is also a member of the chemical engineering, immunology, […]
Light-matter interactions form the fundamental basis for numerous phenomena and processes in optical devices. This talk will cover ultra-high-quality (Q) whispering-gallery-mode (WGM) optical microresonators which have an unprecedented capability to trap light in a highly confined volume smaller than a strand of human hair. Light-matter interactions are significantly enhanced in high-quality WGM resonators, creating the […]
The solutions to many of society’s most pressing problems rely on the discovery of materials with unprecedented physical and chemical properties that are tailored to an application of interest. Typically, it is not a matter of incremental improvements over existing technologies; rather, there is often an urgent need to identify new kinds of materials altogether. […]
Photonics serves as the backbone of modern information infrastructure, transmitting and processing data at unparalleled speeds with minimal energy consumption by harnessing the inherent parallelism, high-frequency operation, and expansive bandwidths. In the past decade, the surging advancements of artificial intelligence has revolutionized the traditional definition of computing algorithms. By bridging the gap between optical hardware and software-defined functionality, programmable integrated […]
The U.S. Department of Energy’s Energy Earthshots Initiative aims to accelerate breakthroughs of more abundant, affordable and reliable clean energy solutions, to tackle the toughest remaining barriers to addressing the climate crisis and achieving net-zero carbon emissions by 2050. Specifically, the Hydrogen Energy Shot seeks to reduce the cost of clean hydrogen by 80% in […]
Abstract: Large pre-trained models trained on internet-scale data are often not ready for safe deployment out-of-the-box. They are heavily fine-tuned and aligned using large quantities of human preference data, usually elicited using pairwise comparisons. While aligning an AI/ML model to human preferences or values, it is important to ask whose preference and values we are […]
This will be a hybrid event with in-person attendance in Levine 307 and virtual attendance on Zoom. ABSTRACT In this talk, I will discuss how we engineered the foundation of the drone show industry, creating a new form of entertainment that rivals traditional fireworks. Our journey began at Pennovation, where we designed and tested our […]
