My research expertise is varied; currently I hold the position of Associate Principal Scientist in Oral Formulation Sciences at Merck. Here I am a member of a dynamic, driven team responsible for the development of orally available compounds for the treatment of various diseases. Previously I was an Engineer at Celgene where I developed sound manufacturing processes for drug products. Briefly I was a Scientist in the Department of Analytical and Material Science at Sun Chemical. Primary responsibilities throughout my career have involved the characterization of laboratory and client-generated samples using numerous analytical techniques. Statistical analyses such as PCA and cluster analysis were routinely used to drive decisions for the improvement of products. Before this position, I was employed as a Research Associate in the Analytical Development: Small Molecules department at Takeda Pharmaceuticals after completing bachelor's degrees in chemistry and math. In 2012, I left this position to pursue my doctorate in chemical engineering. My dissertation research focused on the dynamics of bimetallic precious metal catalysts used in the steam reforming of oxygenated fuels.
