About me

I have a master's degree in Medical Microbiology and obtained my PhD from Manipal University, India in 2015. I am a bacteriologist with extensive experience in phenotypic and genotypic characterization of bacterial pathogens of public health relevance. My research mainly focusses on:
a) detection and characterization of resistance mechanisms among Gram negative bacilli
b) Evaluation of novel antimicrobials and new diagnostic methods
c) antimicrobial combination testing.

Research

Molecular epidemiology
Mechanisms of resistance
Novel diagnostic methods and antimicrobials
Deep sequencing methods
