Seraj has established a well-equipped Plant Biotechnology laboratory at the University of Dhaka.
She is a co-principal investigator of a project in the Generation Challenge Program (GCP)—an initiative to use molecular biology to help boost agricultural production. Seraj has worked on fine mapping of the major QTLs for salinity tolerance in Pokkali, a traditional rice landrace and application of markers to aid breeding programs for incorporation of salinity tolerance in rice. She also works on developing genetically modified rice varieties with improved salt tolerance suitable for growing in the coastal region of Bangladesh.
