Dr.  Saidur R.  Chowdhury is  an  Assistant  Professor in the Civil  Engineering  Department  at  Prince  Mohammad  Bin Fahd  University  (PMU), Al  Khobar,  Saudi  Arabia. He completed  his  PhD  in  Environmental  and  Geo-Environmental Engineering at Western University (UW) in Canada. His doctoral  dissertation  investigated  the performance  of  different  iron  oxide  nanoparticles  and recycled  waste  products  for contaminated water and site treatment. Dr. Chowdhury is a Professional Engineer (P.Eng) in the province of Ontario in Canada. Dr. Chowdhury has over two years of postdoctoral experience at both Western and Simpson Environmental  Corporation  in Burlington,  Ontario  as  well  as  University  of Saskatchewan.  He  also  worked  as an Environmental Research Manager at Toronto Inspection Ltd. in Canada.  He  has  published  scientific  papers  in  refereed journals, and  international  conference  proceedings,  as  well  as technical  reports  for  different environmental consulting companies in Canada. UW has acknowledged his research contribution by honoring him with the prestigious R.M. Quigley Award (2011) for Research Excellence. 

Dr. Chowdhury has been involved in designing remediation methods for contaminated sites in the Greater Toronto Area (GTA), Ontario, Canada. He is registered with the Ministry of Environment and Climate Change to act as a Qualified Person (QP) for Environmental Site Assessment (ESA) and treatment under Ontario Regulation 153/04. His research interests are in the general areas of environmental and geo-environmental engineering; the application of nanomaterials for environmental remediation technologies; recycled waste products for environmental remediation; the development of reactive media for water or wastewater treatment; and resource recovery. Dr. Chowdhury is also interested in studying the occurrence, fate, and transport of contaminants in natural and engineered systems. His career vision is to design, analyze, and develop reactive media for environmental remediation and to propose tools for the restoration of contaminated environments.
