Onur Cil, MD, PhD

Dr. Onur Cil is a pediatric nephrologist and physician-scientist. Cil Lab’s research focus is small molecule drug discovery and drug repurposing for treatment of renal, gastrointestinal and cardiovascular diseases. Ultimate goal of our research is advancing our discoveries to clinical trials and establishing better and safer treatments. Our research is focused on membrane proteins including calcium-sensing receptor (CaSR), SLC26A3 (DRA), SLC26A4 (Pendrin), SLC26A6 (PAT1), CFTR, TMEM16A and urea transporters.
