ESE Fall Colloquium Seminar – “Distributed Estimation Under Privacy and Communication Constraints”

Zoom - Meeting ID: 282 221 4402

Distributed estimation is a central task in modern data science, where datasets are often generated from distributed sources or are too large to be stored on a centralized machine, and communication is subject to bandwidth and privacy limitations. In this talk, we will consider the problem of estimating high-dimensional distributions and their parameters from distributed […]

Fall 2021 GRASP SFI: “Diversity and Inequality in Social Networks”

Abstract: Online social networks often mirror inequality in real-world networks, from historical prejudice, economic or social factors. Such disparities are often picked up and amplified by algorithms that leverage social data for the purpose of providing recommendations, diffusing information, or forming groups. In this talk, I discuss an overview of my research involving explanations for algorithmic […]

CBE Seminar: “Spatial and Dynamical Control in Metabolic Engineering Using Organelle Engineering and Optogenetics”

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

Abstract Metabolic engineering aims to rewire cellular metabolism, typically of microorganisms, to produce fuels, chemicals, pharmaceuticals, and other valuable products from renewable resources. However, it is often challenging to achieve the titers, yields, and productivities required for commercial viability. Spatial and dynamical control of engineered metabolic pathways can greatly improve their efficiency to address this […]

MSE Seminar: “Topological Physics: from Photons to Electrons”

Auditorium, LRSM Building 3231 Walnut Street, Philadelphia, PA, United States

There are many intriguing physical phenomena that are associated with topological features --- global properties that are not discernible locally. The best-known examples are quantum Hall effects in electronic systems, where insensitivity to local properties manifests itself as conductance through edge states which are insensitive to defects and disorder. In this talk, Dr. Hafezi will […]

BE Seminar: “Phage and Robotics-Assisted Biomolecular Evolution” (Emma Chory)

Moore 216 200 S. 33rd Street, Philadelphia, PA, United States

This seminar will be held live and broadcast on zoom - check email for link or contact ksas@seas.upenn.edu. Evolution occurs when selective pressures from the environment shape inherited variation over time. Within the laboratory, evolution is commonly used to engineer proteins and RNA, but experimental constraints have limited our ability to reproducibly and reliably explore […]

GRASP on Robotics: “The Importance of Pneumatic Actuation in Adaptive Robotic Devices”

Abstract: Soft pneumatic actuators have become a popular implement in modern robotic systems due to their intrinsic mechanical compliance, which affords researchers levels of robustness and adaptability that can be difficult to achieve in rigid-body, motor-driven devices. However, with the physical advantages of these versatile actuators come significant challenges in sensing, feedback control, and sustainable, […]

PICS Colloquium: “Kinetic theory for superparameterization of sea ice dynamics”

PICS Conference Room 534 - A Wing , 5th Floor 3401 Walnut Street, Philadelphia, PA, United States

Arctic sea ice comprises of many ice floes whose dynamics is driven by oceanic/atmospheric currents and floe-floe interaction. Models of the effective sea ice dynamics  at large scales typically employ hydrodynamic equations of motion, such as mass and momentum conservation, with complex constitutive laws attempting to capture the rheology of sea ice as a continuum. Although hydrodynamic sea ice models […]

CBE PhD Dissertation Defense | “Process Development and Modeling for the Advancement of Direct Air Capture Technologies”

Zoom - Email CBE for link

Abstract:  "As the catastrophic effects of climate change are felt throughout our global society, we must take immediate action. A portfolio of climate solutions must include both deep and robust decarbonization, and systems to remove carbon dioxide directly from the atmosphere. One promising suite of carbon removal technologies is Direct Air Capture (DAC). DAC refers […]

MEAM Seminar: “Robotics Goes Soft: Challenges and Achievements, for New Robotics Scenarios”

Zoom - Email MEAM for Link peterlit@seas.upenn.edu

Largely inspired by the observation of the role of soft tissues in living organisms, the use of soft materials for building robots is recognized as one of the current challenges for pushing the boundaries of robotics technologies and building robotic systems for service tasks in natural environments. The study of living organisms sheds light on […]
