Dr. Khan received his master's degree in Chemistry with distinction in 2010 at the School of Physical Sciences of Shah Jalal University of Science and Technology, Sylhet, Bangladesh. At that stage, he focused in the synthesis of organometallic materials which have non-linear optical properties to use in optoelectronic devices. In 2013, he had obtained the highly prestigious pre-doctoral fellowship funded by Catalan Government, Spain, and conducted his research at the Faculty of Chemistry, Universitat Rovira i Virgili (URV), Tarragona, Spain. He had completed his doctoral degree in Nanoscience and Nanotechnology and awarded with international distinction, and published articles in high ranked international journals and visited different countries of the world to exchange knowledge and view of research. His current research interests are synthesis, sensors/biosensors, wearable sensors, nanomaterials and miniaturization to make cost-effective biomedical devices. Presently, he is working as Assistant Professor in Chemistry in the School of Physical Sciences, Jashore University of Science and Technology, Jashore, Bangladesh.
