Dr. Zheng had extensive research skills and a solid, interdisciplinary background in extracellular vesicles, optical sensing and imaging, nanomaterials, and infectious diseases. He received his Ph.D. from Peking University in 2018. His research focused on the designing of nanomaterials with novel optical properties for sensing and antibacterial applications. Particularly, he has developed several nanomaterials-enhanced assays for the rapid sensing of a variety of targets for rapid food/environmental safety monitoring and disease diagnosis. At Tulane University, Dr. Zheng's research focuses on the development of nanoplasmonic enhanced immunoassay (NEI) for detecting and quantifying tuberculosis-associated extracellular vesicles biomarkers, with a goal of a validated test for tuberculosis diagnosis with high accuracy and reproducibility. Dr. Zheng' work has resulted in more than 30 publications in peer-reviewed journals including Nat. Biomed. Eng., Lancet Microbe., Nano Today, Nano. Lett., Anal. Chem., Small, Sci. Adv., Angew. Chem., ACS Appl. Mater. & Interfaces etc.
