Dr. M. Qasim Mehmood has received his BS degree in Electronic Engineering from International Islamic University Islamabad (IIUI) in 2008. Same year he started his MS (in Electronic Engineering) from Ghulam Ishaq Khan Institute (GIKI) and joined there as a Lecturer upon completion of his MS in 2010. He served GIKI as a lecturer till joining National University of Singapore as a PhD scholar (in Electrical and Computer Engineering) in July 2011. He completed his PhD, in January 2016, under the supervision of Prof. Cheng-wei Qiu, Prof. Aaron Danner and Dr. Teng Jinghua. His research interests were in the area of optics and nano-photonics: more precisely it included the demonstration of exotic phenomena (via ultra-thin nano-structured devices) e.g., on-chip orbital angular manipulation, beam-steering, spin-orbital coupling, three dimensional holography, polarization filtering and light absorption etc. All of his work incorporated vigorous theoretical modelling, numerical calculations and experimental investigations. He gained considerable experience of nano-fabrications at Institute of Material Research Engineering (IMRE) A*STAR Singapore and Spin Energy Lab (SEL) NUS Singapore. His PhD research-works were published in various prestigious journals such as Advanced Materials, Laser Photonics Reviews and Advanced Optical Materials etc.
Currently, he is working as an Assistant Professor (since Feb 2016) and heading NanoTech research-lab (www.nanotechlab.itu.edu.pk) at Information Technology University of the Punjab Lahore, Pakistan. NanoTech lab earned notable repute, of high impact and quality research, in a short-span. Since its establishment in March 2016, it has produced significant works in world’s well-known ISI-indexed journals such as Advanced Functional Materials, ACS Nano, Light Science & Applications, Optics Letter, Applied Physics Letters, Annalen der Physik and Chinese Physics Letters etc. Its research-scope spans over the broad range of emerging areas form fundamental investigations to innovative applications. On the fundamental side, areas like applied electromagnetics, microwave engineering, antenna engineering, semiconductors, nano-optics and nano-photonics, plasmonic metamaterials and nano-antennas are targeted. On the applied side, microwave system and antennas are designed and developed for various applications such as communication, radar front-end and bio-imaging etc. He has active research collaborations locally (with LUMS, NUST and GIKI) and internationally (with NUS, POSTECH, SUTD and Wuhan University) where his students (MS and PhD) and research associates travel for research-attachments.
