Huadong Tang, PhD

My research as a student in pharmaceutics focused on examination and evaluation of allometry technique in predicting human PK parameters; Development of new models for predicting human PK parameters; Examination of species/body weight dependency of allometry technique for predicting human PK parameters; Mathematical examination of the functionality of correction factors used in allometry; Pharmacokinetic modeling of drug disposition in hair; Development of a pharmacokinetic-based model for predicting the efficiency of hemodialysis; Determination of the distribution pattern of P-glycoprotein in the gastric intestinal tract of micropigs. I am currently at Wyeth Research doing pharmacokinetics within drug safety and metabolism. I Assist Bioanalytical R&D and Drug Safety staff in the interpretation of PK and TK data, perform simulations to aid study design and assist in the design. I conduct analysis of specialized PK or PK/PD experiments. I also predict human pharmacokinetic parameters and determine the First Dose in Humans to aid clinical study design, and also design and analyze GLP/non-GLP PK and TK experiments Preparation and review of technical reports, regulatory submissions and manuscripts for publication.
