The last fifteen years have seen the most spectacular rise of a class of materials initially known as the hybrid halide perovskites, with the field quickly evolving to encompass all-inorganic halide perovskites and double perovskites, low-dimensional hybrid halide materials, and quantum dots. With intense worldwide research activities over the last decade, photovoltaic, light-emissive, and...
We develop quantum devices to enable the implementation of quantum technologies based on controlling light at the single photon level with the aim of on-chip integration and novel instrumentation. Future quantum communication and sensing will require high-performance quantum devices able to generate and detect light one photon at a time. Schemes to manipulate light on-chip, based on integrated...
The Standard Model (SM) of particle physics provides a very good description of nearly all available experimental data. Notable exceptions are Dark Matter (DM) and the Baryon asymmetry of the universe (BAU, the question why we only see matter, but not antimatter). These questions point towards physics beyond the SM (BSM). While DM points towards some new so far undiscovered symmetry, the BAU...
Early Childhood Development serves as a crucial foundation for lifelong learning, with basic science education playing a key role in fostering curiosity, critical thinking, and problem-solving skills of young children. However, many practitioners looks like face challenges in integrating science concepts into playroom activities. Understanding how practitioners apply basic science in these...
The optics of the human eye is at once simple, robust, and remarkably well adapted to the needs of the visual system. However, how different optical aberrations, whether naturally occurring or artificially induced, affect vision remains a central question in ophthalmology and visual optics. One of the most powerful approaches to investigate this involves the use of adaptive optics (AO) visual...
Pulsars are spectacular, enigmatic, astrophysical objects that emit regular pulsations across the electromagnetic spectrum. Moreover, they are thought to be factories of cosmic rays as well as gravitational waves upon merging events, making them true multi-messenger objects. They are Nature’s exquisitely accurate timepieces, being the super-dense remnants of supernova explosions. They are...
Quantum communication holds the promise of ultra-secure information transfer and lays the foundation for the future quantum internet. At the heart of this vision is the ability to distribute entanglement and quantum keys over long distances, including via satellite. My research focuses on free-space quantum communication, and most recently, on implementing satellite-based quantum links. In a...
