The aim of my lab is to design engineering solutions for tackling infectious disease. Our approach is based on the biohybrids design: we integrate biological entities (particularly bacteriophages and bacteriophage derived tools) along with synthetic nanoparticles, biopolymers, and hydrogels, to develop novel materials and devices that address challenges in human health and the health of our environment. The biohybrids design concept spans across multiple disciplines and integrates engineering with molecular biology, materials science, and chemistry.

Research Platforms

Platform A: Alternative antimicrobials

The main focus of this class of projects is on bacteriophages (or phage for short) and phage lysins.  A bacteriophage is a virus that infects bacteria. We isolate phage form clinical and environmental samples and design bacteriophage antimicrobials for treating difficult-to-treat infections and bacterial biofilms. We further investigate the interaction of such therapies with the host microbiome.  

Platform B: Targeted, nano-drug delivery solutions

Targeting drugs directly to the site of infection with the potential to include other active agents to disrupt the biofilm matrix would increase the efficacy of treatment for invasive bacteria infections.  We focus on developing smart nanoparticles and bioactive materials, with controlled release.

Platform C: Bioactive coatings and hydrogels

We combine biological colloids with non-biological colloids and surfaces to form materials and interfaces that are bioactive (exhibit specific interaction with one or a range of desired biomarkers) and multifunctional (e.g., electrically conductive, antibacterial, photoactive, repellent, etc.) to form multifunctional, bioactive, soft biomaterial.

Did you know…

Multiple MSc and PhD opportunities exist. Highly motivated students with background in engineering, sciences, or health sciences, interested in pursuing a Ph.D. or M.Sc. degree in one of the above-mentioned research areas are encouraged to contact me directly ( Please include a curriculum vitae and a brief statement of interests. Please see our website for a list of available projects.

Opportunities also exist for undergraduate students seeking to do research for credit (or just for fun).

We have an open position for a postdoctoral fellow to be filled immediately. The required qualifications are:

  1. microbiology lab skills
  2. experience in molecular cloning

Experience in site directed mutagenesis, working with bacteriophages or phage display is a plus. 


I am a chemical engineer, fascinated by microbiology. For the past 10 years, I have been working on employing the intelligence of biological systems (specifically bacteriophages and bacteria) to tackle the outstanding challenges related to human health. I joined the Chemical Engineering Department at McMaster in July 2016. I am also an associate member at the Micheal DeGroote Institute for Infectious Disease ResearchThe Farncombe Institute and the School of Biomedical Engineering.
