Sean Bittner is currently the Director of Programs for new ventures at Proxima Clinical Research, a contract research organization that serves the emerging drug and medical device industries. 

Prior to joining Proxima, Sean was a graduate research fellow at Rice University, where he studied applying 3D printing to tissue engineering of bone and cartilage. While in graduate school, Sean developed a passion for personal and professional development, particularly leadership development. He completed over 200 hours of training in coaching skills and interpersonal dynamics and was recently credentialed as an Associate Certified Coach with the International Coaching Federation. Using the skills developed during his leadership training, Sean went on to manage three graduate student teams to design experiments for his PhD work, and two short-term consulting projects with life science companies in Houston. As the Director of Programs for new ventures at Proxima, Sean is excited to support the development of life science startups from idea to market.
