Introduction

Our main research scope is to design nature-inspired adhesive materials via catechol or gallol redox chemistry, potential application of which is cardiovascular and neural system. In detail, we have focused on developing a variety of adhesive biomedical formulations (i.e., hydrogels, particulates) exhibiting neuron repair, hemostatic effect, minimally invasive, hemostatic medical devices, adhesion/affinity-based drug-delivery carriers as well as 3D printable inks based on mussel-inspired catechol/its derivatives chemistry for wet-resistant adhesion. The ultimate goal of our research is to design a new generation of biomaterial-based practical medical tools capable of diagnosing and treating actual patients.​

Introduction

The overarching goal of our research is to understand the psychological and neurobiological mechanisms that underpin how we experience our own emotions and evaluate the emotions of others. Our lab examines how different aspects of affective information are encoded, manipulated, and integrated in the brain. We also investigate individual differences in such processes on both behavioral and neural levels, and their implications for mental health. We combine experimental psychology, multimodal neuroimaging (fMRI, dMRI), and computational tools to answer research questions pertaining to affective science.
