Dr. Sulaem Musaddiq Laskar has earned the degree of Doctor of Philosophy in 2019 from Indian Institute of Technology Guwahati and the degrees, B.E. in Civil Engineering and M.Tech. in Earthquake Engineering from Assam Engineering College and National Institute of Technology Silchar respectively. During the tenure of Ph.D. thesis work, Dr. Laskar worked on Structural Engineering with specialization in Repairing and Retrofitting of RC Structures. He studied the behaviour of Portland cementless mixes and their efficacy as concrete repairing and strengthening agent. Dr. Laskar was selected by National Project Implementation Unit of Ministry of Education (erstwhile, Ministry of Human Resource and Development) under the quality improvement program for underperforming engineering institutes of India funded by TEQIP III. Dr. Laskar was appointed in Jorhat Engineering College under this program. Later, he moved to National Institute of Technology Mizoram to serve as faculty member in the Department of Civil Engineering. Dr. Laskar’s current research interests include non-destructive testing and retrospective design of structures; repairing and retrofitting of structures; alkali activated and light weight concrete. His other research interests are on study of behaviour of RC members under static and dynamic loading; bridge engineering; and sustainable materials in construction industry. Dr. Laskar has completed a NPIU and TEQIP III sponsored research project and has published many research papers in SCI indexed journals of Q1 category. He has also executed many consultancy projects related to structural analysis and design; concrete and steel quality control; non-destructive testing; bridge design.
