CIS Seminar: “Breaking and Building End-to-End Encrypted Systems”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Abstract Today’s computer systems and their owners fail to protect data. Exacerbating this are new threats stemming from the rise of cloud computing. The consequences are dire: sensitive information like financial statements, medical records, and private messages are disclosed to malicious parties. In my research at the intersection of security, cryptography, and systems, I work […]

ESE Seminar: “Joint Wireless Communication and Sensing in Terahertz Spectrum”

Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Abstract Millimeter-wave and terahertz bands are emerging as the most promising spectrum to meet the data-rate and latency demands of future wireless applications, including virtual reality and autonomous cars. Moreover, large spectral availability and mm-scale wavelength provide the possibility for ubiquitous and high-resolution sensing. My research builds a foundation for joint communication and sensing in […]

BE Seminar: “Engineering Stem Cells to Create Novel Delivery Vehicles”

Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

Synthetic biology has transformed how cells can be reprogrammed, providing a means to reliably and predictably control cell behavior with the assembly of genetic parts into more complex gene circuits. Using approaches and tools in synthetic biology, we are programming stem cells with novel genetic tools to control genes and pathways that result in changes […]

CIS Seminar: “Building Data-Driven Computers: Reimagining Systems to Reduce the High Costs of Large-Scale Data Processing”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Abstract: A wide range of application domains are emerging as computing platforms of all types become more ubiquitous in society.  Many of these applications are data centric, and spend a significant fraction of their time on accessing and processing very large datasets.  Examples of these applications include graph frameworks, precision medicine, computer vision, deep learning, […]

Abstract By enabling optical microsystems with new functionalities, improved system performance, and reduced size, weight, and power, integrated photonics is positioned to enable next-generation optical technologies that facilitate revolutionary advances for numerous fields spanning science and engineering, including computing, sensing, communications, displays, quantum, and biology. An emerging class of integrated photonic systems is integrated optical […]

MEAM Seminar: “Scalable Algorithms for the Computational Modeling of Complex Multi-Physics Systems”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

The computational modeling of complex multi-physics problems often requires specialized approaches in the formulation, implementation, and deployment of algorithms that lie outside the scope of conventional practice in physics-based modeling and simulation. In this talk I will present three examples of problems in which the synergistic combination of advanced algorithms, and state-of-the-art software implementations on […]

CANCELLED: MEAM Seminar: “Wind Farm Dynamics and Power Optimization in Realistic Atmospheric Boundary Layer Conditions”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

The study of wind farms within realistic atmospheric boundary layer conditions is critical to understand the governing physics of the system and to design optimal operational protocols. Historically, control protocols have optimized performance of individual wind turbines resulting in aerodynamic wakes which typically reduce total wind farm power production 10-20% and increase the cost of […]

Cancelled: CIS Seminar: “The Value Alignment Problem in Artificial Intelligence”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Abstract: Abstract: Much of our success in artificial intelligence stems from the adoption of a simple paradigm: specify an objective or goal, and then use optimization algorithms to identify a behavior (or predictor) that optimally achieves this goal. This has been true since the early days of AI (e.g., search algorithms such as A* that […]

Cancelled: CIS Seminar: “Deep Probabilistic Graphical Modeling”

Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

Abstract: Deep learning (DL) is a powerful approach to modeling complex and large scale data. However, DL models lack interpretable quantities and calibrated uncertainty. In contrast, probabilistic graphical modeling (PGM) provides a framework for formulating an interpretable generative process of data and a way to express uncertainty about what we do not know. How can […]
