Our mission is to devise innovative analytical systems for biomedical and environmental monitoring applications, with a special focus on low-cost, accurate, and simple-to-use platforms. We take a convergent approach to engineering sensors through innovations at multiple fronts, from material engineering and device engineering to system integration and data analytics. Our research is cross-disciplinary, spanning electrical engineering, device physics, electrochemistry, materials, data science, applied physics and chemistry, and life science (with a special interest in microbiology).
