She joined the (NRC) in Egypt in 1977 under the supervision of Prof. Dr. Samia Temtamy Prof. of Human Genetics. Since then she is working extensively in the fields of Clinical Genetics and Cytogenetics. Her current research interests include: Clinical Syndrome Identification, Dysmorphology, CHD, Skeletal Dysplasia, Sexual Differentiation Disorders, and Detection of Mutations in rare Autosomal Recessive Disorders .She works also as Clinical Cytogeneticist. She is focusing on genotype-phenotype correlations in genetic diseases, and on genetic counseling.
