PROFILE

SHORT BIOGRAPHY

Since 2004, I have been conducting research works in Virology, Molecular epidemiology, Environmental and Industrial Microbiology, Bioinformatics, Emerging and Re-emerging diseases, Clinical microbiology, Molecular biology etc. During the last 17 years, I have been associated with research works in public health issues in Bangladesh and global perspectives. As success of my research works, more than 100 research articles and seminar papers have been published from internationally reputed journals. At present, I am conducting collaborative research works with Professors from University of Georgia, USA; University of Pittsburg, USA; University of Tokyo, Japan; University of Taif, Saudi Arabia; Nihon University, Japan; and Chiang Mai University, Thailand.
