Assistant Professor of Pharmaceutics
B.Pharm., Shri BM Shah College of Pharmacy, North Gujarat University, IndiaM.Pharm., National Institute of Pharmaceutical Education and Research (NIPER), IndiaPh.D., NIPER, India
Dr. Patel has received a Ph.D. in Pharmaceutics in 2010 from the National Institute of Pharmaceutical Education and Research (NIPER, India), an M. Pharm. in Pharmaceutical Technology (Formulations) from the NIPER, and a B.S in Pharmacy from the North Gujarat University, India. He joined the Division of Pharmaceutical Sciences in fall 2012 after working at the Department of Pharmaceutics, University of Minnesota, where he worked on many research projects related to preformulation, formulation development and pharmaceutical processing. He has published 15 research articles, filed 2 patent applications, worked on various industry-sponsored projects and received research grant.
He is actively involved in research areas of pharmaceutics like – (i) Pre-formulation profiling (physico-chemical characterization, solubility, permeability), (ii) Pharmaceutical material characterization (amorphous, polymorphism, pseudo-polymorphism, salt, co-crystals), (iii) Manufacturing sciences (mechanical property, tableting, granulation, flow property) and (iv) Drug delivery to improve bioavailability. The research efforts are focused to “build-the–quality” within the drug products through pharmaceutical Quality by Design (QbD) concept. Using QbD, pharmaceutical quality is assured by understanding and controlling formulation and manufacturing variables.
Dr. Patel teaches various courses in both the graduate and entry-level programs.
• Solid state: PXRD, DSC, MTDSC, TGA, isothermal nanocalorimetry, DVS, FTIR, microscopy (polarized/hot stage), contact angle measurement
• Powder processing: Ring shear cell, instrumented tablet press, Presster, nanoindenter, texture analyzer
• Preparation and solid state characterization of amorphous dispersions, polymorphs, salts and hydrates
• Solubility, physical stability (solid and solution state), drug-excipient compatibility studies
• Quantification of crystalline content in formulation matrix using PXRD
• Immediate/modified release oral dosage forms, self-microemulsifying drug delivery systems, micronized suspension, nanosuspension, amorphous solid dispersion, cyclodextrin complexes and spray-dried composites
