Current Position: Professor and Chairperson, Department of MNS (Mathematics and Natural Sciences), BRAC University, Bangladesh since 2nd April 2017 till date. 
My latest fields of research are Laser-induced Breakdown Spectroscopy (LIBS), Laser Raman Spectroscopy (LRS), and nano-particle fabrication by Laser ablation technique. 
I had been a teacher and a researcher (joined as a lecturer in 1972) in the physics department of the University of Dhaka for 43.5 years (1972 – 2016) of which as a selection grade professor of physics of the University of Dhaka from December 1994 to June 2016. I retired from Dhaka University on 30th June 2016. 
I was the Vice-chancellor for two months and the Pro-Vice-Chancellor for six and a half years at, the University of Dhaka. I was the director of the semiconductor Technology Research Centre for more than seven years. I was also the chairman of the physics department for three years, the Dean of the faculty of science, and the provost of Surja Sen Hall (student dormitory, for more than six years). 

I was also an adjunct professor of Physics, at Daffodil International University (DIU) from September 2009 to March 2017.
• All through first-class in all examinations from S.S.C. to M.S. (Thesis group, Nuclear Physics)
• Ph.D. in Solid state physics and Post-Doctoral Research in Laser Physics and Non-linear Optics.
• I am a member of the prestigious a) American Physical Society (APS) and the 
b) American Chemical Society (ACS).
• I am a fellow of the Bangladesh Physical Society (BPS). I am also a member of the Bangladesh Asiatic Society.
• More than 75 publications in International (with good impact factors) and National peer-reviewed journals, book chapters, invited talks, and conference proceedings.
• My Research Interest Score (30 Oct 2023) was 481.2, which is higher than 86% of 
Research Gate users globally (17 million, May 2020) and citation of my papers is 678 up to 30 Oct. 2023.
• Professor of Physics, since August 1988 & Selection Grade Professor (top 20 % of all Professors) of Physics since 1994, University of Dhaka.
• Editor: The Dhaka University Journal of Science. (July 2009 – June 2011)
• Peer Reviewer of the following nine International Journals (with good impact factors).

(i) Optics and Laser Technology, Elsevier (U.K.)
(ii) IEEE/OSA Journal of Lightwave Technology. (the U.S.A.) 
(iii) Optics and Lasers in Engineering, Elsevier (U.K.) 
(iv) Analytical Methods, RSC Publishing (U.K.)
(v) Journal of Optical Society of America (JOSA), (U.S.A.) 
(vi) IEEE Journal of Quantum Electronics (U.S.A.)
(vii) Energy & fuels, American Chemical Society (ACS) (U.S.A.)
(viii) Spectroscopy Letters, Taylor & Francis Publications (U.K., U.S.A.)
(ix) Analytical Methods, RSC Publications (U.K.)
• Two of my papers [publication number 35 (for once) and publication number 43 (for 
nine times), see my list of publications] were amongst the top 25 Hottest Articles as the most read paper for several quarters.
• One of my papers (publication number 57) was listed as number 1 paper in the list of top 20 papers by BioMedLib library listing of leading papers in the related field since 2012. 
• I introduced the course on laser physics at the postgraduate level for the first time in the physics department of the University of Dhaka, Bangladesh in 1984.
• Established the modern optics and laser laboratory in the department for the first time in 1984.
• Played a pivotal role in establishing the Centre for Advanced Research in Sciences (CARS) in the university in 2005 while I was pro-vice-chancellor (vice president) of Dhaka University.
• Coordinator of the Non-Linear Optics and Laser Spectroscopy laboratory of the above center (CARS) for the years 2009 to 2014.
• Presented several invited talks at home and abroad.
• I was invited to submit nominations for the award of the Nobel Prize in Physics in 1994, 2013, and also for 2016 by the NOBEL COMMITTEE FOR PHYSICS, Royal Swedish Academy of Sciences.
• I have so far written six chapters for different books on the invitation for publishers in the U.S.A.

Major scientific/technical accomplishment
• Lowest ever (sub-ppm level) detection limit of As in water by LIBS technique using 
adsorption and pre-concentration enhancement technique. This is a very significant
improvement of the lowest detection limit of trace elements, particularly in liquids, by
LIBS technique.

• Simultaneous determination of lifetimes of excited atomic/ionic states and atomic 
excitation temperature decay constant using LIBS as yet another novel application of 
LIBS.

• Determination of ash content in coal without burning the coal in a single
spectroscopic measurement using LIBS.

• Detection of rare earth elements in beach sands of Bangladesh using LIBS.

• Nanoparticle fabrication by Laser Ablation technique and explanation of different 
observations by Froehlich equation (condition). Until that time different observation
regarding nano-particle fabrication by laser ablation technique was unexplained.
More importantly, all these experimental works were done at the University of Dhaka, Bangladesh, thereby I developed an excellent experimental laser physics and laser spectroscopy research laboratory in a developing country like Bangladesh, where resource constraints and lack of infrastructure facilities are of main concern.
