I hold a Bachelor of Science in Physics, a Master of Science from Anna University, India, a Master of Technology in Materials Science from the Indian Institute of Technology Kanpur, and a PhD in Physics from the Australian National University. My research expertise spans semiconductor materials, nanostructures, and optoelectronic devices, with a focus on the epitaxial growth, fabrication, and characterisation of III–V and III-nitride semiconductors for photonic and electronic applications.
 
My research career has included positions as a Scientist at CSIR–Central Electronics Engineering Research Institute (CEERI), India, and postdoctoral appointments at the Australian National University and the University of Adelaide (now Adelaide University). Across these roles, I have investigated semiconductor materials and devices for light-emitting diodes, ultraviolet photodetectors, photovoltaic devices, and near- and mid-infrared lasers. My work integrates advanced epitaxial growth techniques, micro- and nanofabrication, and structural, optical, and electrical characterisation to understand the relationships between material properties and device performance.
 
My research has contributed to the development of GaN/InGaN LEDs, GaN/AlGaN nanostructures for ultraviolet optoelectronics, flexible GaN photodetectors, lattice-matched InGaAsP materials for multijunction solar cells, and GaAs- and GaSb-based infrared lasers. I have also gained experience in thin-film oxide semiconductors, electrochromic materials, and display technologies, and have contributed to postgraduate teaching through curriculum development, laboratory instruction, and lectures.
 
To date, I have authored and co-authored more than 15 peer-reviewed publications, and my work has been recognised with an ACS Editors' Choice Award. My research interests lie at the intersection of physics, materials science, and engineering, with an emphasis on advancing semiconductor materials and devices for next-generation photonic and electronic technologies while fostering interdisciplinary collaborations.
