Dr.  Saidur  R.  Chowdhury  is  an  Assistant  Professor in 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  (e.g.  Ni  smelter  slag)  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  the  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  referred 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 involved in designing remediation methods for contaminated site in 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; application  of nanomaterials  for  environmental remediation  technologies;  recycling  waste  product  for environmental  remediation;  development  of  reactive media  for  water  or  wastewater  treatment  and  resource recovery. Dr Chowdhury is also interested in studying the contaminant occurrence, fate, and transport 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.
