Phase-Matching in Dirac-Cone-Based Zero-Index Metamaterials, at CLEO: Science and Innovations (San Jose, CA), Sunday, June 5, 2016:

Using nonlinear scattering theory, we simulate nonlinear signal generation in 2-dimensional zero-index metamaterials based on a photonic Dirac cone at the G point. We observe unique phase-matching in multiple simultaneous directions as the index approaches zero.
Non-equilibrium materials by fs-laser texturing and hyperdoping of silicon, at AFOSR Ultrashort Pulse Laser-Matter Interactions PI Review (Arlington, VA), Thursday, June 2, 2016:
talk_2640.pdf
Ultrafast-laser hyperdoped semiconductors have begun to be utilized for optoelectronic applications, but there is a need to better understand their fundamental physical properties. In this presentation, we discuss recent work on the basic science of ultrafast-laser structuring, time-resolved melting, resolidification, and hyperdoping, and the optical and electronic properties hyperdoped silicon. These aspects of ultrafast-laser hyperdoped semiconductors are central to hyperdoped materials science and device design.
Peer Instruction, at Colorado State University at Pueblo (Pueblo, CO), Monday, May 2, 2016:
talk_2623.pdf
The basic goals of Peer Instruction are to encourage and make use of student interaction during lectures, while focusing students' attention on underlying concepts and techniques. The method has been assessed in many studies using standardized, diagnostic tests and shown to be considerably more effective than the conventional lecture approach to teaching. Peer Instruction is now used in a wide range of science and math courses at the college and secondary level. In this workshop, participants will learn about Peer Instruction, serve as the "class" in which Peer Instruction is demonstrated,... Read more about Peer Instruction
Assessment: The silent killer of learning, at Colorado State University at Pueblo (Pueblo, CO), Monday, May 2, 2016:
talk_2624.pdf
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...

Confessions of a converted lecturer, at 10th Annual Academic Success Lecture, Texas Woman's University (Denton, TX), Friday, April 29, 2016:
talk_2612.pdf
I thought I was a good teacher until I discovered my students were just memorizing information rather than learning to understand the material. Who was to blame? The students? The material? I will explain how I came to the agonizing conclusion that the culprit was neither of these. It was my teaching that caused students to fail! I will show how I have adjusted my approach to teaching and how it has improved my students' performance significantly

Getting every student ready for every class, at China Machine Press Conference (Beijing, China), Wednesday, April 27, 2016:
talk_2635.pdf
Over the past decades there has been a concerted push away from passive lecturing to active engagement in the classroom. A successful implementation of the so-called flipped classroom requires students to come to class prepared, either by reading the textbook or watching a pre-recorded video. A variety approaches have been devised to get students to take responsibility for this information transfer, but none manage to get all students to participate, compromising the in-class activities. I will present a new approach to get every student to prepare for every class using a new social learning... Read more about Getting every student ready for every class
Less is More: Extreme Optics with Zero Refractive Index, at 8th International Symposium on Advanced Optical Manufacturing and Testing Technologies ( AOMATT 2016) (Suzhou, China), Tuesday, April 26, 2016:
talk_2560.pdf
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 of the nanostructure. We present an in-plane metamaterial design consisting of silicon pillar arrays, embedded within a polymer matrix and sandwiched between gold layers. Using an...
