    Muhammad Younus joined the Department of Chemistry, SUST in 1992. In 1993, he moved to the University of Cambridge UK for higher studies. After completion of his Ph. D. from the Department of Chemistry (Supervisor: Professor Lord J. Lewis), University of Cambridge, UK, (1997) and post-doctoral research with Professor Nicholas J. Long of the Department of Chemistry, Imperial College of Science, Technology and Medicine, London, UK, he moved back to his home country Bangladesh in 2001. While serving as an assistant professor, associate professor and professor of Chemistry (2001-2009), he continued research works in his own laboratory. Within this time, he also worked at the Department of Chemistry, University of Bath, UK as an academic visitor with Professor Paul R. Raithby, and at the Department of Chemistry and Biochemistry, Miami University, Oxford, Ohio, USA as a post-doctoral fellow with Dr. Scott J. Hartley. In 2011, he won a competitive research grant of four hundred and fifty thousand dollar under Higher Education Quality Enhancement Project (HEQEP) of the University Grants Commission of Bangladesh to renovate research laboratories and to procure state-of-the-art instruments for materials chemistry research. Now, he is leading a research group of four M.Phil. and two M.S. students.
