Specialization: Characterization of membrane transporters, peptide-based drug delivery, placental and fetal fatty acid homeostasis, and PK/PD

Education

BS Biochemistry, 1988, Cook College, Rutgers, The State University of New Jersey.
MS Pharmaceutical Chemistry, 1995, The University of Kansas

Research: Characterization of membrane transporters, peptide-based drug delivery, placental and fetal fatty acid homeostasis, and PK/PD

Dr. Knipp researches the molecular and functional characterization of human intestinal oligopeptide transporters, the effect of xenobiotics on placental fatty acid homeostasis and fetal development, and the effects of processing induced dosage form variation on clinical performance in in vitro and in vivo models.
