Antimicrobial ResistancE (AMR)
We develop precision antimicrobial strategies to combat multidrug-resistant infections, integrating bacteriophage therapy, nanotechnology, and host-directed approaches.
Protein Conformational Diseases (PCDs)
We uncover how gut microbes and their metabolites directly regulate host proteostasis, a fundamental process disrupted in Alzheimer’s and Parkinson’s disease.
What is
Antimicrobial resistance
“the ability of a microorganism to stop antimicrobial from working against it” – WHO
Antibiotics
Lack of novel antibiotic classes leads to limited treatment options
Resistance
Constantly increasing resistance poses a threat on a global scale
Bacterial Infections
It is estimated that by 2050, antibiotic resistance will claim 10 million lives annually
Our Approach
Targeting the host and bacterial resistance mechanisms allows us to circumvent antibiotic resistance
How is
Human microbiota linked to neurodegeneration?
Somehow bacteria that are part of our very own microbiome affect the way proteins fold in our brains. Among many factors, antibiotics, diet, and aging affect our microbiota. A dysbiosis of the human gut microbiota has been linked to neurodegeneration. A number of factors may be contributing.
Inflammation
Increased presence of Gram-negative bacteria can trigger chronic inflammation that was shown to enhance neurodegeneration
Aggregation-prone proteins
Bacteria can secrete amyloid-like proteins that disrupt host proteostasis. Such proteins can migrate from the gut into the brain
Displacement
Bacteria from various microbiome sites (i.e. oral) were found in brains of patients with neurodegeneration
Our Approach
We employ the C. elegans intestine as a test tube to study the effect of bacterial colonization on host proteostasis

Learn more about our projects
Antibiotic Resistance
We employ in vitro tissue-culture models to identify modulators of bacterial entry, inhibitors of intracellular survival, and enhancers of the immune response
Proteostasis
We study host-pathogen interaction using C. elegans
Alternatives
We employ non-traditional approaches to target AMR in Gram-negative bacteria, specifically P. aeruginosa. Such approaches include specific targeting of bacteria by phages and restoring the efficacy of antibiotics by inhibiting efflux pumps.
