Biography and Research Information
OverviewAI-generated summary
Pierre Alusta's research focuses on the detection and enumeration of microorganisms, particularly in environmental and pharmaceutical contexts. He has investigated methods for identifying specific bacterial species, such as the Burkholderia cepacia complex, using flow cytometry and fluorescence-labeled oligonucleotide probes. His work also includes developing flow cytometric assays to assess the viability and persistence of bacteria like Salmonella enterica in various conditions, including nuclease-free water and in the presence of antimicrobial agents like thymol. Alusta has also explored metagenomic approaches coupled with enrichment techniques for detecting microorganisms in potable groundwater and in non-sterilized pharmaceutical products. His research extends to the direct detection and identification of viruses in saliva using mass spectrometry. Alusta has published 28 papers, with 243 citations, and maintains an h-index of 9. He frequently collaborates with researchers at the National Center for Toxicological Research, including Soumana Daddy Gaoh, Dan A. Buzatu, Youngbeom Ahn, and Angel Paredes.
