"Then there is the danger that the ignorant man may easily underdose himself, and by exposing his microbes to non-lethal quantities of the drug, make them resistant.” - A. Fleming

Antimicrobial Resistance

Our ultimate goal is to find effective alternatives to antibiotics. We have identified a novel way to enhance the ability of the host to clear infections by antibiotic-resistant bacteria

Protein Conformational Diseases

Our ultimate goal is to prevent and treat neurodegenerative diseases. We are identifying bacteria and their respective signals that affect host protein homeostasis

What is

Antimicrobial resistance

“the ability of a microorganism to stop antimicrobial from working against it” – WHO


Lack of novel antibiotic classes leads to limited treatment options


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.


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


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

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


We study host-pathogen interaction using C. elegans 


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.
