The trend of engineering practice has been changing with the socio-economic structure and industrial diversification. Global economy, advancements of new science and changes of technology have been playing important roles in this changing trend. Therefore, to cope with the changing situation, engineers must have the ability to identify, formulate and solve new engineering problems, and understand the impact of their solutions in a global and social context.

Dr. Khan believes, in engineering education system, problem based learning can be an effective way as it helps students to solve open-ended engineering and scientific problems. “Mixed lecture” based classes with hands-on laboratories and tours to the real engineering sites strengthen the learning abilities of students. Interaction with industry personnel provides ideas to the students about their future prospects and responsibilities. Such industrial know-how motivates students, as they can correlate their course materials with the engineering profession. Moreover, multidimensional competitions among students can improve their skills which will be helpful in their future career.

Dr. Khan’s goal in teaching is to help students to develop their skills and knowledge, to know their strengths and comfort zones, and learn to address critical scientific questions. I comprehend my teaching responsibilities are Research Supervision, Classroom Teaching and other Departmental Administrative Works.

Research Supervision: Dr. Khan’s research interests and activities include Biotechnological and Environmental issues. He believes all research students should learn the fundamental background of their research topics so that they can tackle practical problems. He also believes in empowering research students, so that they can discover critical scientific problems and learn to solve them independently. Dr. Khan finds it is more important for students to structure their thinking and define the critical scientific questions before they start looking for the solution.

Dr. Khan expects his research students to regularly give seminars and group presentations. Research students should report their research findings in written form and when applicable, they should organize results and prepare drafts for scientific publications.

Last but not the least, it is equally important to meet students informally at tea, coffee, or lunch to allow free and vibrant discussions.

Classroom Teaching:  Dr. Khan plans to provide Effective Teaching in the classroom, which will address deductive, inductive and global methods of teaching. He personally plans to adapt inductive method integrated with conventional deductive method to provide the appropriate learning environment.

It is important to bring out the best from students. Classroom assessment should target improving engineering perceptions of the students, make them more creative and keep them keen towards the course contents. Besides, to ensure proper assessment and grading, it is important to use a proper marking scheme and to give regular feedback to the students. Hence, Dr. Khan would like to design classroom evaluation to support students’ learning styles.

Research Interest:

Dr. Khan’s research interest includes chemical, biotechnological and environmental engineering. His research group : ‘BET Group’ (Bio and Environmental Engineering Group), aims to address different scientific, engineering and socio-economic issues related to Health, Food, Bio-fuel, Wastewater Management, Electronic Waste Management, and Cleaner Production.

Currently BET Group is working on different biotech and environmental issues which include food processing and preservation, artificial fruit ripening, low-cost detection of biomarkers and toxins, and 3D molecular modelling of antibody structure and antibody-antigen interactions.

Research Background:

Dr. Khan completed his PhD in “Bioactive Papers: Printing, Activity and Stability”, from the Dept of Chem Eng, Monash University, Australia in 2010. His research team has pioneered the bioactive paper research in Australia, an activity now growing to a multi-million $ interdisciplinary platform where Monash University is recognized as one of the world leaders. For his PhD research, he received the Mollie Holman Doctoral Medal for the best Monash PhD thesis and the Kenneth Hunt Medal for the best Engineering PhD thesis. As a recognition of Research Excellence in his PhD, he received ‘Post Doctoral Fellowship Award’ from the Department of Chemistry, McGill University, Montreal, Canada to continue my work on Bioactive Papers as a part of NSERC-CRSNG’s Bioactive Paper Network, the largest network in this area in the world. His Post-Doctoral research work encompassed Theoretical and Experimental research. The Theoretical research work aimed to perform molecular modelling of building blocks of Picloram antibody, 3D Homology modelling of Antibody Binding Fragments, and Quantum Calculation of Antibody-Antigen Interaction Energies at different physiological conditions. The Experimental research work aimed developing Antibody active paper and cellulose beads to detect and filter bacteriophage ‘T7’.

Bioactive paper is a revolutionary technology as the price of the device is typically 1000 times cheaper than competitive technologies. Dr. Khan’s main contribution in this research has been to significantly improve the concept, and to enable large scale manufacturing by developing efficient processes based on functional printing on paper. He has made his discovery and insured its proof of concept/development by leading a multi-disciplinary team involving senior experts in rural medicine/haematology, biochemistry/immunology, chemistry, surface science and chemical engineering. In his PhD and Post-Doctoral research, he has initiated, often in a team, a series of projects that have been both critical and strategic. Dr. Khan’s research work on bioactive papers is highly quoted and highlighted in over 10 countries and 25 journals/organizations including the Royal Society of Chemistry Journal “Chemistry World”, MIT Technology Review, American Chemical Society, NY Times, India Times, and Science Daily. For his research work in Bioactive paper, Dr. Khan won the 'Young Innovator Award 2012' entitled '[email protected] Awards' organized by the 'MIT Technology Review Inc' to recognize the top innovators in the Asia-Pacific regions under the age of 35. 

Dr. Khan’s research interest also lies in Environmental Engineering. He worked (2004-06) in an international Pollution Abatement Research Project in Bangladesh funded by USAID (USA), DFID (UK), European Commission and Govt. of Bangladesh. The work was undertaken by Bangladesh Centre for Advanced Studies, Stockholm Environment Institute and University of Leeds, UK. Under that project, he got the opportunity to work inside the industry to identify and reduce pollution from sources. He also worked as an independent Environmental Consultant to design the ‘Effluent Treatment Plant, ETP’ and to develop the ‘Waste Management Plan’ for local industry.

Dr. Khan’s research interest extends to Engineering Education. He has pioneered ‘Undergraduate Thesis Competition’ and ‘Poster Competition’ in the Dept of Chem Eng, Bangladesh Uni of Eng and Tech (BUET). Besides, he is the founder and the Editor of ‘ChE Thoughts’, the first Chemical Engineering and Science Magazine in Bangladesh and South-East Asia.
