Management Team

​Ronald J. Shebuski, PhD

President & CEO

Dr. Shebuski was hired as President of Cylerus in 2010, bringing extensive research and management experience in biotechnology development, including large pharmaceutical firms (Upjohn, SKF, Merck) as well as smaller companies.

Stephen R. Hanson, PhD

Founder & Board Chair

Cylerus technology is based on work from the laboratory of Dr. Stephen Hanson, former Chairman of Biomedical Engineering, Oregon Health & Sciences University (Portland OR). His studies over many years had led to the conclusion that preservation of graft patency would be best achieved by local, endoluminal delivery of an antiproliferative agent like sirolimus, an approach that is now the basis of Company’s technology platform and intellectual property.
