                        EMEA ERP Implementation Controller
                        Prague, Czech Republic

                        I’m here to help build a completely new finance structure in Europe, the Middle East and Africa (EMEA), lean and efficient. We all have the future of a great company in our hands. And I couldn’t pass up the opportunity to create an efficient finance team in the region and help shape the new organization. A big part of that will be successfully implementing Oracle EnterpriseOne (E1) in EMEA finance, a tool that will allow us to build and expand our Information Technology solution to fit the needs of the business.

                        What are the plans for the new company’s product pipeline?


                        We will continue to grow our product pipeline by investing in both our core businesses and in near-adjacent therapeutic areas. That means looking at areas other than pain management where we can easily make the most of our Research & Development expertise in drug formulation. It also means strengthening our internal businesses with acquisitions and licensing agreements that fit well with our portfolio. For instance, we recently acquired CNS Therapeutics, a St. Paul, Minnesota-based (U.S.) small specialty pharmaceuticals company that develops high-quality products which are injected directly into the spinal cord.
