İncilay Lay

İncilay Lay has graduated from high school of Ankara Atatürk Anadolu in 1990 and Ankara University Faculty of Medicine in 1996. She has completed her Medical Biochemistry Specialization Training in January 2001 and her Biochemistry PhD in 2004 at Hacettepe University Faculty of Medicine. She became Assistant Professor in 2005 and Associate Professor in 2011.

Between 2002-2003, she has performed researches on molecular basis of Lysosomal Storage Disorders at 'Hospital for Sick Children, Research Institute, Department of Structural Biology and Biochemistry' in Toronto, Canada with NATO Postdoctoral Scholarship by Scientific and Technical Research Council of Turkey (TUBITAK). With her works she has been awarded as a Young Investigator at 'The 22nd World Congress of Pathology and Laboratory Medicine', Korea. She has continued her researches on new therapeutic approaches in Lysosomal Storage Disorders as a visiting scientist at 'Hospital for Sick Children, Research Institute, Genetics and Genome Biology’ in Toronto, Canada with TUBITAK International Post-Doctoral Research Fellowship (2219) between 2011-2012.

Her main interest and working area is Inherited Metabolic Diseases. She is interested in molecular basis, diagnosis and prenatal diagnosis, new therapeutic strategies of Lysosomal Storage Disorders; neurodegenerative metabolic diseases; protein folding disorders; relationship between diseases and polymorphisms.

Since April 2012 she is working in Clinical Chemistry Laboratories of Hacettepe University Hospital.
