Emerging edge AI systems call for device-level approaches that are inherently low-power, secure, and capable of managing uncertainty. In this talk, I will share our recent exploratory efforts toward realizing on-device probabilistic intelligence using custom-designed semiconductor devices. I will introduce Gaussian transistors that support analog Gaussian activation and probabilistic inference by harnessing device-level variability. These […] |

The global climate crisis demands a shift to renewable energy sources. Solar photovoltaics (PVs) are widely considered the most feasible renewable technology to meet global energy demands, and solar photo-electrocatalysis is a promising approach to decarbonize industrial chemical production. However, scaling solar energy harvesting technologies to meet energy demands must be done economically and sustainably, […] |

MEAM Seminar: “Leveraging Robot-Based Haptic Dyads to Improve Community-Based Stroke Rehabilitation”
MEAM Seminar: “Leveraging Robot-Based Haptic Dyads to Improve Community-Based Stroke Rehabilitation”
Disabilities related to aging and stroke impact functional independence and quality of life for millions of older adults, creating a growing need for scalable, accessible rehabilitation solutions. Community-based robotic therapy that leverages social interaction and haptic feedback offers a promising approach, particularly for individuals with motor and cognitive impairments. This seminar presents work exploring how […] |

This is a virtual event ONLY with attendance via Zoom. ABSTRACT The talk will introduce several topics in low-resource and multilingual NLP – in the domain of disinformation combatting, through works done at the Kempelen Institute of Intelligent Technologies in Bratislava – and also in the more general context of efficiently adapting large language models […] |

Abstract: Precise regulation of gene expression is essential for controlling developmental programs, maintaining cellular identity, and ensuring proper tissue function. Dynamic interactions between proteins and cis-regulatory elements integrate molecular mechanisms and extracellular signaling to achieve precise control of transcriptional activity. In this thesis, I investigate protein-DNA-mediated transcriptional regulation across two distinct developmental systems: mouse embryonic […] |

Affecting roughly 2 in 1000 infants in the USA, Cerebral Palsy (CP) is the most common cause of motor impairment in children. CP has no cure, but motor therapy is an effective tool for providing rehabilitation. Although therapy is most effective before the age of 2, early CP detection is difficult and labor-intensive, making the […] |

Spin lattice dynamics (SLD) modeling is an approach to modeling magnetic interactions at the nanoscale. Current spin lattice dynamics models do not model magnetoelastic effects well, giving non-physical lattice parameters and poorly modeling behavior like forced volume magnetostriction. A new model, based on a temperature dependent offset that subtracts out the part of the magnetic […] |

Virtually everyone today is aware of the mRNA vaccine for COVID, which saved many lives and earned the Nobel Prize for Drs. Drew Weissman and Katalin Kariko. The vaccine consisted not only of mRNA that coded for the COVID spike protein, but a protective lipid nanoparticle envelope that carried the RNA to cells in the […]

To meet net-zero carbon emissions targets by mid-century, up to a ~30-fold increase in wind power capacity is required. Acceleration to this rate requires urgent improvements to efficiency and reliability of installed wind farms, as well as cost reductions for future offshore farms. To expand energy production, wind turbines are rapidly increasing in size, wind […]

Abstract: Rare earth elements (REEs) are essential for clean energy technologies including batteries for electrical vehicles, wind turbines and LED screens due to their unique magnetic, optical, and electronic properties. Efficient methods for their recovery and separation are urgently needed to meet the growing demands of a rapidly evolving green economy worldwide. However, current separation […] |

For decades materials engineers have been inspired by biology to create improved properties, for example nacre-inspired hierarchical structures to improve toughness, tree-inspired vasculature to deliver fluids that can react and heal an interface, and mussel-inspired strong underwater adhesives utilizing cation-pi interactions. Now, the bioengineering toolset has reached a maturity where we can start to employ […]

The rapid integration of AI into educational settings presents opportunities and challenges—this talk will discuss findings from three large-scale field studies investigating the impact of AI on student learning. First, we found that unfettered access to ChatGPT negatively impacted short-term student learning outcomes. Second, to understand longer-term effects, we examined learning in chess academies. Contrary […]

Abstract: First, I will outline our work on overcoming barriers to desert rehabilitation for urban greening, landscaping, and regional food security. In arid regions, freshwater is scarce, sandy soils lose water and fertilizers rapidly, which stifles plant growth. Our team has developed two complementary solutions: (i) Superhydrophobic Sand (SHS)1 — a plastic-free, bio-inspired mulch that […] |

On the real line, a random walk that can only move in the positive direction is very unlikely to remain close to its starting point. After a fixed number of steps, the left tail has a Gaussian profile, under minimal assumptions. Remarkably, the same phenomenon occurs when we consider a positive random walk on the […]
