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
Active learning and Perusall: Sharing Practices for Successful Learning Engagement, at Congreso Internacional de Lingüística Computacional y de Corpus, Universidad de Antioquia, Medellin, Colombia (virtual), Thursday, October 22, 2020:
It has been suggested the lack of interaction in large lecture courses is to blame for the many problems facing these courses: declining enrollments, low attendance, poor evaluations, and disappointing retention. We offer a way of redesigning the classroom so interaction is introduced in many aspects of the course. This approach has shown to be effective by many instructors in a broad variety of environments. I will demonstrate some of the tools we have developed to foster this interaction.
Education, post-coronavirus, at Jornadas Virtuales de Educación, CeRP del Norte, Uruguay, Wednesday, September 30, 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.

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. This zero index can only be achieved by simultaneously controlling the electric and magnetic resonances...

Social Learning in Times of Social Isolation Tuesday, September 8, 2020:

Learning is a social experience — it requires interactions and interactivity. This is true not only in the physical classroom, but even more so now that education has moved online. I will demonstrate how to move information transfer and sense making online and make it interactive, promoting social interactions between students. I will also discuss how to promote intrinsic motivation to learn by implementing project- and team-based learning in the classroom.
