Research: Phase transformations, physical and chemical stability, water-solid interactions, amorphous systems and solid dispersions

Our overall goal is to enhance drug delivery by optimizing and understanding the physicochemical properties of drugs and excipients.  Of particular interest are amorphous solid dispersions which are used to improve the oral delivery of poorly water-soluble drugs. We are also interested in the stability of  pharmaceutical salts and the impact of excipients on product performance. For these types of solids, it is extremely important to understand drug-excipient interactions as well as the imapct of water on stability. We achieve an improved molecular level understanding of pharmaceutical materials and formulations through the use of high resolution analytical techniques. Some of the analytical techniques that we use are infrared, Raman, ultraviolet and fluorescence spectroscopy, X-ray powder diffraction and differential scanning calorimetry.

Current Research Projects

 
1. Stabilization of amorphous solid dispersions through rational polymer selection
2. Second harmonic generation for the characterization of nanoscale crystallization. (collaboration with Professor G. Simpson, Chemistry, Purdue University)
3. Techniques to assess amorphous-amorphous miscibility
4. Novel polymers to stabilize amorphous solids(collaboration with Professor K. Edgar, Virginia Tech)
5. Stabilization of supersaturated solutions
6. Effect of polymers on crystal growth
7. Probing hygroscopicity and reactivity in crystalline and amorphous salts
8. Improving the solubility of phytochemicals
9. Disproportionation of pharmaceutical salts
10. Deliquescence in blends - chemical stability and powder properties (collaboration with Professor L. Mauer, Food Science, Purdue University)
