My research interests broadly span targeted and phenotype-based drug development, with an emphasis on infectious diseases. During my Ph.D. studies under the supervision of Dr. Matthias Götte at McGill University in Montreal, Quebec, Canada, I characterized the biochemical mechanisms of action of novel small molecule inhibitors of HIV-1 reverse transcriptase with unique resistance profiles (pyrophosphate analogues, nucleotide-competing inhibitors and delayed chain terminators). Further development of these new classes of compounds will hopefully lead to expanded options for treatment-experienced patients who develop resistance to components of their drug regimens.

I am currently conducting post-doctoral research in the laboratory of Dr. Jair Lage de Siqueira-Neto, CDIPD, where I am actively involved in the development of high-throughput screening assays and profiling of small molecule and natural product libraries against neglected tropical diseases (Trypanosoma cruzi, Leishmania donovani and the Zika virus), as well as pancreatic cancer. Using cell-based phenotypic screens and high-content cellular imaging, our group is engaged in the identification and lead optimization of drug-like molecules for these diseases.
