I graduated to be among the top ten of college of science graduates in 2002 with Bachelor of Science in Biology. I had worked as a biology assistant for six months at the same department in College of Science, Salahaddin University-Erbil. I assisted with labs of cell biology and microtechnique. I was granted Fulbright scholarship in 2004, sponsored by Institute of International Education, US State Department. I completed my pre-academic English language training at the University of Oregon, Eugene, Oregon, USA. Then I moved to College Station, in the state of Texas. I completed my Master’s of Science in Public Health at the Department of Environmental and Occupational Health in 2006. My research focused on studying genotoxicity of different polycyclic aromatic hydrocarbon (PAH) compounds. I investigated the potential of PAHs on the induction of DNA adducts in mouse tissues.

       Afterward, I returned to the Department of Biology at SU to work as an assistant lecturer. I taught different practical courses: molecular biology, genetics, biodiversity, ecology, and pollution. I published two papers where I investigated the toxicity of pesticides on different organs in small mammals. I started my Ph.D. in Toxicology and Cancer Biology in 2011 at the University of Kentucky, Lexington, Kentucky, USA. My Ph.D. was sponsored by Human Capacity Development Program-Ministry of Higher Education and Scientific Research. My research mainly focused on studying interactions, localizations, and functions of antioxidant-related proteins in different lung cancer cell lines. During which I published six papers. Upon completing my Ph.D. in 2016 I returned to work at the Department of Biology at SU. Since then I published four addtional papers. Currently, I work as assistant professor at the Department of Clinical Biochemistry, College of Health Sciences, Hawler Medical Univeristy.
