Chief Executive Scientist


Leveraging broad experience supporting product development, registration, and life-cycle management and an extensive network of experts and contract services providers, Dr. Jenke uses good science, practically applied, to address and overcome the challenges associated with managing interactions that occur between drug products and their manufacturing, packaging and delivery systems, insuring that such interactions (for example, extractables, leachables and drug binding) do not adversely affect the product’s key quality attributes including safety, purity, efficacy, stability, and suitability for use.
