Dr. Saima Riazuddin is currently an associate professor of Otolaryngology-Head and Neck Surgery at the University of Maryland, School of Medicine. She is also an adjunct professor at the National Center of Excellence in Molecular Biology, University of the Punjab, Pakistan. Dr. Riazuddin received her Bachelors of Science at the University of the Punjab in Pakistan and then obtained her PhD in Molecular Genetics from the same University. Dr. Riazuddin completed her post-doctoral training at the National Institute of Deafness and Other Communication Disorders, National Institutes of Health (NIDCD/NIH). She was subsequently appointed as an Assistant Professor in the Division of Pediatric Otolaryngology Head & Neck Surgery, at the Cincinnati Children’s Hospital and the Department of Otolaryngology at the College of Medicine, University of Cincinnati. At the Cincinnati Childrens Hospital Dr. Riazuddin was the recipient of the Research Achievement award for her dedicated commitment and excellence in the pursuit of inner ear research at the Cincinnati Children’s Hospital. Dr. Riazuddin’s research has been published in highly ranked scientific journals. Dr. Riazuddin is the principal investigator of two NIH R01 grants and multiple other national and international grants.

The focus of Dr. Riazuddin’s laboratory is investigating the genetic factors associated with hearing impairment and understanding the precise mechanism of various forms of hearing dysfunction using human pedigrees, mutant mouse models and zebrafish as tools. A complementary study in her lab is focused on identifying the modifier genes that can preclude the effect of disease causing mutations and the mechanism, by which they confer resistance to pathogenic mutation. The long-term goal of this research is to contribute to a better understanding of the molecular mechanism of inherited hearing loss with the aim of discovering drugs or treatments to prevent this disease.
Lab Techniques and Equipment:
- Molecular Genetics including genetic mapping, linkage analysis, next generation sequencing, cloning, gene expression, protein interaction studies, transgenic and gene targeted mice and zebrafish knockodown.
- Tissue culture studies including cell lines and explant cultures
- Immunohistochemistry, western blot, insitu hybridization
Positions are available for postdocotoral fellows. We are seeking talented postdoctoral fellows to participate in new project to investigate the molecular mechanisms of inherited hearing impairment. The experiments involve interdisciplinary approaches ranging from gene identification studies in human pedigrees using the next generation sequencing and linkage analysis to analyses of gene function using in vitro approaches. The projects take advantage of transgenic, gene targeted knockout and knock-in mice to evaluate the hearing phenotype in mice and to determine the pathophysiology resulting from loss of function. In addition for ex vivo studies, zebrafish morphants and CRISPR based mutants are routinely developed and evaluated. This is an opportunity to become involved in cutting edge research that is tightly coordinated between in vitro and in vivo experimental approaches.
