Research Interests

My research explores the fundamental and applied aspects of optical physics and quantum optics. The focus of my work is broadly defined by exploring novel properties of light and its potential for developing quantum technologies. This is a fast-developing research field with tremendous potential to impact different areas of science and engineering, such as quantum metrology, quantum communications, and quantum information science. Some of the research that I have pursued includes (i) the development of quantum measurement schemes that allow amplification of small physical parameters and characterization of photonic states, (ii) the demonstration of highly efficient sources of entangled photons and engineering of complex high-dimensional states of light, (iii) the implementation of quantum protocols that utilize optimization algorithms to effectively use the information content in each photon, and (iv) the exploration of physical conditions under which light is forced to manifest new surprising properties.
