Introduction

Dr. Asim Laeeq Khan is Associate Head of Department at the Department of Chemical Engineering, COMSATS University Islamabad, Lahore Campus, Lahore, Pakistan. He received his Bachelor's degree in Chemical Engineering from the University of the Punjab in 2002 and worked as Process Engineer at Chlor-Alkali Plant of Sitara Chemicals Industries Ltd. for three years. He entered graduate school of Chalmers University of Technology, Sweden for his Masters in 2005 and followed it with doctoral and post-doctoral studies from KU leuven Belgium.

In the latest rankings of productive scientists of Paksitan released by 'Pakistan Council for Science & Technology', Dr. Khan was ranked among the top scientists in the field of 'Engineering' across Pakistan. He has published a number of journal articles in high-impact journals of Chemical Engineering with a total impact factor of more than 300. His work has been cited more than 1500 times with an overall h-index of 20. He is also reviewer of pretigious journals including 'Journal of Membrane Science', 'Separation & Purification Technology, International Journal of Hydrogen Energy' etc.

Dr. Khan is founder of Membrane Systems Research Group (Energy & Environment) at COMSATS, Lahore. He has broad interests in industrial separations, particularly the use of membrane technolgy for energy applications. He has been working in the area of membrane science and technology at both industrial and academic research level. During his tenure at the Center for Surface Chemistry and Catalysis (COK), KU Leuven, he did pioneering work in the area of high-throughput (HT) experimentation in membrane based gas separations.

Research Facilities
The research labs are COMSATS are equipped with state of the art equipment for characterization and performance testing of membranes. At the level of synthesis, our research lab is equiped with automated casting device (Doctor's blade) with the provision of casting at different casting speeds. Phase Inversion is the major technique that is being used in our lab for the synthesis of membranes. In addition, an automatic dipcoating machine is available for the synthesis of composite membranes. A number of membrane testing set-ups are also available in the 'Membrane Lab'. These include testing set-up for 'Gas Separation', 'Pervaporation' and 'Nanofiltration' membranes.
 
At the level of characterization, following characterization equipment are available:
  • SEM, TGA, DSC, XRD, GCMS, UTM, FTIR, BET , UV-VIS, HPLC
