Chemical and Biomedical Engineering Our research is inspired by light as a sustainable energy source to
drive chemical processes, and its minimal invasiveness to achieve biomedical
diagnosis and therapy. Our overall theme is
concerned with designing, developing and understanding new processes, and
redesigning and improving existing ones, to simultaneously enhance economic
value and reduce the impact on the environment, so as to advance healthcare
and enable the necessary societal transformation to a sustainable future. We focus on enhancing solar-enabled processes such as solar cells and
solar-driven fuel production via materials architecture engineering from nano-to-micron scale to improve
photoconversion efficiency and charge transport kinetics. We are also
interested in the use of novel and sustainable approaches in these processes,
with a strong regard to the impact on the environment and
the long-term sustainability of the processes developed. Our work in
photo-enabled biomedical processes centers at the interface of chemical,
materials and biological engineering. Our goal is to integrate useful
components/processes into multifunctional systems for simultaneous diagnosis
and light-triggered therapy, and to interrogate the fundamental mechanisms
dictating the combinatorial performances of these processes. Through the pursue of the two areas discussed above, our
multidisciplinary and collaborative efforts have motivated a cross-over into
other non light-mediated processes such as sustainable separation technology,
bio-inspired fuel cells, tissue-inspired engineering and high performance
biosensing. |
