Research Interests

I have a variety of research interests related to therapeutic drugs, including development of analytical methods, investigations of pharmacokinetics, molecular and cellular investigations of mechanisms of action and resistance, and clinical studies. These have provided an assortment of projects for Laboratory Medicine residents and fellows, as well as undergraduate, graduate and medical students. Current research falls in three basic areas:

  • the pharmacology of drugs used in the treatment of HIV infection;
  • various investigations related to Laboratory Medicine; and
  • Leishmaniasis and its treatment.

AIDS pharmacology

Pharmacokinetics and pharmacodynamics of drugs used to treat HIV infection and associated opportunistic infections. We are currently studying interactions between anti-HIV drugs (reverse transcriptase inhibitors and protease inhibitors) and drugs used to treat substance abuse (methadone, buprenorphine).

Laboratory Medicine

We carry out various investigations, both analytical and clinical, related to clinical chemistry, therapeutic drug monitoring and toxicology.

The leishmaniases are a family of diseases caused by the parasitic protozoan Leishmania . We have been able to reproduce the entire life cycle in vitro and have used this system to study the regulation of gene expression during the transformations between amastigote and promastigote life stages. We are currently investigating the composition, mechanism of action and pharmacokinetics of the antileishmanial drugs, sodium stibogluconate and meglumine antimoniate.

We carry out various investigations, both analytical and clinical, related to clinical chemistry, therapeutic drug monitoring and toxicology.
