Extreme optics with zero-index metamaterials, at Bertman Lecture, Wesleyan University, Middletown, CT, Thursday, April 29, 2021
Nanotechnology has enabled the development of nanostructured composite materials (metamaterials) with exotic optical properties not found in nature. In the most extreme case, we can create materials which support light waves that propagate with infinite phase velocity, corresponding to a refractive index of zero. We have developed a variety of in-plane metamaterial designs that permit obtaining a refractive index of zero in the optical regime. We will report on some of the exotic physics of zero-index metamaterials, including strong enhancement of nonlinear optical phenomena
Transform your teaching with Perusall, at Webinar, Wednesday, February 24, 2021:
Learning is a social experience — it requires interactions and interactivity. The coronavirus pandemic has been a good opportunity to rethink our approach to teaching. Moving some tasks to an online format suggests that many activities that have traditionally been synchronous and instructor-paced, can be made asynchronous and self-paced. Through Perusall, Eric Mazur, Balkanski Professor of Physics and Applied Physics at Harvard University, will demonstrate how to move information transfer and sense-making...

Subcellular surgery and nanosurgery, at Chemistry Seminar, Middle Tennessee University, Friday, February 12, 2021

We use femtosecond laser pulses to manipulate sub-cellular structures inside live and fixed cells. Using only a few nanojoules of laser pulse energy, we are able to selectively disrupt individual mitochondria in live bovine capillary epithelial cells, and cleave single actin fibers in the cell cytoskeleton network of fixed human fibro-blast cells. We have also used the technique to micromanipulate the neural network of C. Elegans, a small nematode. Our laser scalpel can snip individual axons without causing any damage to surrounding tissue, allowing us to study the function of individual...

Assessment: The Silent Killer of Learning, at Cardiff University, UK, Wednesday, January 27, 2021:
Why is it that stellar students sometimes fail in the workplace while dropouts succeed? One reason is that most, if not all, of our current assessment practices are inauthentic. Just as the lecture focuses on the delivery of information to students, so does assessment often focus on having students regurgitate that same information back to the instructor. Consequently, assessment fails to focus on the skills that are relevant in life in the 21st century. Assessment has been called the "hidden curriculum" as it is an important driver of students' study habits. Unless we rethink our approach to...

Education, post-coronavirus, at Day of Educational Transformation, KAIST, South-Korea, Thursday, December 3, 2020:
The rapid transition to online teaching necessitated by the coronavirus pandemic has been a good opportunity to rethink our approach to teaching. Moving to an online format suggests that many activities that have traditionally been synchronous and instructor-paced, can be made asynchronous and self-paced. What may have seemed like a challenge, is a great opportunity to improve the quality of education.

Transform Your Classroom with Perusall (A workshop), at Webinar, Saturday, November 21, 2020:
Learning is a social experience — it requires interactions and interactivity. The coronavirus pandemic has been a good opportunity to rethink our approach to teaching. Moving some tasks to an online format suggests that many activities that have traditionally been synchronous and instructor-paced, can be made asynchronous and self-paced. Through Perusall, Eric Mazur will demonstrate how to move information transfer and sense-making online and make it interactive, promoting social interactions between students. In addition, he will discuss how the platform promotes intrinsic and extrinsic... Read more about Transform Your Classroom with Perusall (A workshop)
