Over 17 years of research experience in the general areas of pharmaceutical sciences and drug delivery systems, with special expertise in the area of formulation design and process development. Research areas are: 1) formulation and process design of complex drug delivery systems (such as liposomes, nanoparticles, transdermal, implant, emulsions, microspheres, pediatric etc.); 2) improving drug product quality as well as process understanding through Quality by Design (QbD) approach and Process Analytical Technologies (PAT); 3) development of in vitro release performance tests for traditional (tablets, capsules, gels, emulsions) as well as complex drug delivery systems (microspheres, liposomes, nanoparticles, transdermal, implant, emulsions, ointments, creams, etc.); 4) evaluation of bio-equivalence of complex drug dosage forms; 5) design and evaluation of abuse deterrent formulations (ADF) for opioid analgesics, 6) 3-dimensional printing of various dosage forms for pharmaceutical application, 7) continuous manufacturing of pharmaceutical dosage forms and 8) univariate and multivariate models (chemometrics, mega-data analysis) development for various phases (polymorphs, amorphous, solvates, salt or base) quantification in the drug products. Other areas of intense research interest include protein and peptide delivery using polymeric materials in formulation design and risk analysis.
