My research is focused on the manufacturing sciences of solid oral dosage forms with specific emphasis on 1) Design of robust formulations based on physicochemical, mechanical and flow properties of drug, excipients, and their interactions in a powder mixture. 2) Computer-aided next generation material properties visualizations.

Current research include:

• Tableting and simulation
• Mechanical property
• Powder flow
• Powder mixing and lubrication
• Machine learning (ML) based composition selection
