Assistant Professor

Office: Science and Engineering, Room 321







Being trained as an engineer my long-term goal is to apply quantitative analyses to investigate problems in computational and systems biology, microbial ecology and environmental microbiology and engineering. Specifically I am interested in understanding how bacteria populations dynamics evolve as a function of interspecies interactions
and environmental pressures.

Current Projects

Inference and prediction of multispecies microbial communities dynamics

Multispecies microbial communities have a fundamental role in the functioning of many natural, engineered and host-associated systems.

Thanks to recent advances in molecular microbiology and DNA sequencing we now have an enormous amount of data to be analyzed such that we can now envision a near future where the results of this analysis will assist in the design of bioremediation strategies, biofuels and even rational antibiotic therapies.

In this research project we apply computational models proper of engineering disciplines, statistical inference and wet-lab experimentation to infer microbial ecosystems' structure and response to environmental stimuli and to predict their spatial and temporal dynamics.

Examples of model systems under investigation are the human intestinal microbiota, competition and cooperation in biofilms, microbial dynamics in wastewater treatment applications and microbial dynamics in natural surface water.

Cost-benefit of adaptation to external environment in enterophatogenic bacteria populations

When discharged into the external environment (e.g. natural surface water) enteropathogenic bacteria populations such as enterohemorrhagic Escherichia coli are able to survive for long period of times trough adaptation. This survival is potentially dangerous to human health.  Principles of evolutionary biology state that adaptation to a particular environment may results in the loss of costly traits needed to succeed in other environments. In this research project we develop experimental and computational work to test the hypothesis that enteropathogenic bacteria populations survive in the natural environment by adapting to it and that this adaptation comes at the cost of reduced fitness in subsequent host colonization and toxicity. We use enterophathogenic E. coli O157:H7 as our model system.
