Uniting our lab group's diverse interests is a commitment to improve global health. We are interested in interactions of microbes with the human host in a wide range of contexts, from infection to beneficial colonization to everything in between. We engage in both fundamental research (to understand these complex systems) and translational research to make real-world impact.
One of our unique strengths is that we combine insights and approaches from multiple fields, including : 1) tools for high-resolution, quantitative measurements and 2) computational analyses to give rise to capabilities that haven't previously been possible, but are necessary to understand complex systems like the human-microbe interface and 3) quantitative ideas and tools from biophysics, dynamical systems, and engineering.
For example, in the context of infections, we develop rapid ultrasensitive diagnostics of infectious diseases (including several COVID-19 related projects and antibiotic resistance projects). In another example, we are interested in the interplay of food, gut microbes, and biophysics in human health. We have a number of projects (see the example of our celiac disease project at NIH RePORTER) in which we collaborate with clinicians to understand interactions of microbes with the human host.
In the past, our lab pioneered technologies for performing chemistry in droplet-based microfluidics and other devices, and these technologies are now widely used by many others. Innovative ideas that have been incubating in our lab continue to lead to new, significant projects.
