IrfanAnsari
Irfan Ansari received his Bachelor of Science (Research) and Master of Science in Physics from Indian Institute of Science at Bangalore (India) in 2017. He joined Photonics Research Group in December, 2017 to work on Silicon Optomechanics. His research focus is on exploring the piezoelectric properties of Si-integrated Lead zirconate titanate (PZT) thin films for electro-optomechanical applications.
