Areas of current Research Interest

Nutrition of Biotin- Incidence of biotin deficiency in pregnancy and potential role of biotin deficiency in human teratogenesis; biotin metabolism, particularly degradation and regulation of degradation of biotin; mechanism and regulation of cellular uptake including inborn errors of biotin transport; role of biotin in biotinylation of histones and their potential role on DNA replication or transcription.

Non-radioactive measurement of red cell mass and red cell survival.

Biotinylation of low molecular peptides hormones such as erythropoietin and subsequent quantitation in order to study pharmacokinetics of endogenously secreted erythropoietin and potentially other hormones.
