I am a theoretical condensed matter physicist. Presently, my main research interests are topological phases, such as topological insulators, topological superconductors, or Weyl semimetals, quantum transport, and spintronics. My aim is to develop an analytical theoretical description, often making use of simplified but effective model descriptions. Examples of recent research topics in these fields are: … Continued
My research interests cover both the fundamental physics of mesoscopic transport and wave chaos as well as the practical applications of nanophotonic devices and biomedical imaging. I amparticularly interested in complex photonic systems that have many degrees of freedom in space, time, spectrum that are coupled, allowing use to use the degrees of freedom in … Continued
Our research investigates robustness, tradeoffs and feedback in complex, highly connected systems, and develops computational multiscale models to capture important small-scale interactions and predict large-scale behavior. Our work combines identification of fundamental mathematical and physical principles underlying complexity and high variability with development of mechanistic models and data driven techniques to address multidisciplinary research challenges. … Continued
My current work focuses on the foundations of quantum mechanics and the emergence of spacetime in quantum gravity, with a growing effort in statistical mechanics and complex systems. In quantum foundations, I have been working to understand how the world of our experience emerges out of the quantum state in the Everett formulation. Starting from … Continued
I have been doing research on solid state lighting, photovoltaics, and biophysics since 1998, with a focus on transitioning science discoveries in the renewable energy and energy efficiency areas into commercial products as well as promoting hands-an science education for grades K-12.

I am a particle physics phenomenologist concerned with the relation between theory and experiment. My research has shown how the extreme weakness of gravity, relative to other forces of nature, might be explained by the existence of extra dimensions of space, and how the structure of comparatively low-energy physics is constrained within the context of … Continued
The focus of research in my group lies in the study of interacting electronic systems in low-dimensional structures. We have developed a technique that permits precision contactless determination of electron tunneling into such structures for an unprecedented direct determination of electronic energy levels. This contactless tunneling can even function on insulating samples and give a … Continued
