Dr. Muhammad Usman is currently working as a research fellow at the Centre for Quantum Computation and Communication Technology (CQC2T) and the School of Physics at the University of Melbourne, Parkville Victoria Australia. His most recent work involves modeling and simulations of shallow donor impurities (P, As, Sb, Bi) in silicon for the implementation of spin qubits and quantum logic gates, with the aim towards designing scalable universal quantum computing architectures. As the lead author of a Nature Nanotechnology paper, he has developed world's first atomically-precise metrology technique to pinpoint the exact spatial location of a qubit in silicon, paving the way for robust quantum gates. 

In 2010, Dr Usman was graduated with a Ph.D. from the Electrical & Computer Engineering Department of Purdue University USA, where his thesis studied multi-million-atom modeling and simulations of III-V quantum dots for the design of photonic devices. He was part of a team under Prof. Gerhard Klimeck working on the development of the state-of-the-art atomistic tight-binding simulator NEMO 3D. His PhD dissertation could be found hereSubsequently, from 2010 to 2014, he worked as a researcher at Tyndall National Institute, Cork Ireland. His theoretical work as a team member of the European Union FP7 project BIANCHO contributed towards the demonstration of world's first bismide laser device. Further details of this EU project, including his work are at: 

Dr. Usman is a passionate supporter and contributor to promote STEM education in schools and actively participate in activities to enhance the interest of school students in science subjects. He is a registered scientist in CSIRO's "scientist and mathematicians in schools" program and do volunteer work with a local school to provide assistance for science education.   

Dr. Usman has contributed over twenty-five refereed journal articles (including eighteen as the first author), four book chapters, and his work has been presented in several invited and contributed talks/seminars. He is affiliated with the Network for Computational Nanotechnology (NCN) as a contributing member. He is a co-manager (with Prof. Gerhard Klimeck of Purdue University) of a nanohub group, which administer the training and distribution of NEMO-3D software package. He is a member of the American Physical Society (APS), IEEE, and Purdue Alumni Society. He actively performs referee duties for scientific journals like PRL, Nanoscale, APL, PRB, PRX, Nanotechnology, etc., and served on the scientific committee of IWCE-2016 conference. He is a recipient of the German DAAD fellowship (2010), Purdue's Graduate School Tuition Award (2006), US DOS Fellowship (2005), K.E. Durrani Fellowship (2003), and Government of Pakistan Merit Scholarship (in 1996 and 1998).
