Research Interests:

Research Focus

My research focuses on bacterial resistance mechanisms focusing mainly on Methicillin-Resistant Staphylococcus aureus (MRSA) and resistant mobile genetic elements in gram negatives including extended spectrum β-lactamases and plasmid mediated AMP-C β-lactamases.

Research Interests

My research interests include the use of molecular methodologies for the laboratory diagnoses of infectious diseases. As Associate Director of the microbiology laboratory, I am interested in the use of real-time PCR to develop more accurate, cost-effective and timely laboratory tests. These tests can also aid in detection of antimicrobial resistance, another area of interest. Antimicrobial resistance of interest include Methicillin-Resistant Staphylococcus aureus (MRSA) and resistant mobile genetic elements in gram negatives including extended spectrum β-lactamases and plasmid mediated AMP-C β-lactamases.
