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. Dr. Laskar studied the behaviour of Portland cementless mixes and their efficacy as concrete repairing and strengthening agent. 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. Dr. Laskar’s 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 is currently working as Principal Investigator in a Research Project sponsored by NBCC (India) Ltd. Dr. Laskar has also completed an NPIU and TEQIP III sponsored research project and has published many research papers in SCI indexed journals of Q1 category and book chapters. Dr. Laskar is also a Life member of the Institution of Engineers (India) and Indian Concrete Institute. Dr. Laskar is also serving as a reviewer for reputed national and international journals. Additionally, Dr. Laskar has also completed many consultancy projects related to structural analysis and design; concrete and steel quality control; non-destructive testing; bridge design.
