Research Summary:

Paradigm shifts in biomedical fields often arise from interdisciplinary innovations in tools and measurement methods. Our research group is interested in applying interdisciplinary approaches to develop new tools and methods to solve current challenges in biomedical fields, such as disease diagnostics, medical therapeutics, as well as personalized medicine. Our current research focuses on the integration of micro- and nanotechnology with biology and medicine, and their biomedical applications.

Our research philosophy is “Interdisciplinary Integration and Innovation (I3)”. On the one hand, we apply advanced biochemical approaches (e.g., CRISPR technology, synthetic biology) to investigate novel bioanalytical and clinical research strategies (e.g., Xiong Ding et al., Nature Communications, 2020, 11, 4711). On the other hand, we adapt our new biomedical research findings to microfluidic technology and develop next-generation medical devices/systems for disease diagnostics and therapeutics (e.g., Kun Yin et al., Theranostics, 2019, 9, 2637-2645).

We are a diverse team of scientists & engineers with broad expertise spanning molecular biology, CRISPR technology, synthetic biology, and chemistry to engineering (e.g., biomedical, mechanical, electronic). We have developed a number of innovative biomedical approaches and medical devices/systems for disease diagnostics and treatment (e.g., COVID-19, HIV virus, Zika virus, early cancer screening).

People are the engine and driving force of innovations in our research projects. We always seek highly talented and motivated individuals (e.g., undergraduate, graduate, and postdoc) from different disciplinary backgrounds (e.g., biology, chemistry, biomedicine, and engineering (e.g., biomedical, mechanical, electronic, material)). We welcome inquiries about positions with a cover letter and curriculum vitae by contacting Dr. Changchun Liu via email (
