Monolayer transition metal dichalcogenides (TMDCs) are a class of 2D semiconductors with attractive properties for future nanoscale optoelectronics such as light sources and detectors. However, due to their single molecule thickness, they are sensitive to environmental factors such as moisture, limiting operation of most light-emitting devices to high vacuum conditions. In this talk, I will...   More >

In today's world, the storage and management of information is highly centralized in data-centers. Such a data-center oriented view of infrastructure also shapes the way we think about information security; the de-facto mechanism for security is to draw a perimeter around the infrastructure and protect such perimeter. However, the future is very different. With the advancement of technology,...   More >

Generalization, i.e., the ability to adapt to novel scenarios, is the hallmark of human intelligence. While we have systems that excel at recognizing objects, cleaning floors, playing complex games and occasionally beating humans, they are incredibly specific in that they only perform the tasks they are trained for and are miserable at generalization. Could actually optimizing towards...   More >
