Research

The SARS-CoV-2 pandemic has highlighted the significant impact that a virus can have on the world. The current global situation serves as a reminder of the importance of developing effective tools for controlling the spread of viruses, such as vaccines, rapid diagnostic tests, and a deeper understanding of disease pathogenesis to aid patient treatment.

While viruses can be frightening, they also offer unique opportunities for understanding fundamental biological processes and developing gene therapy candidates. In particular, viral vectors such as AAV and lentiviral vectors have become increasingly valuable in neuroscience research for studying cellular, molecular, and neurocircuit functions.

Our laboratory is dedicated to fighting infectious and non-infectious diseases through traditional and modern tools and technologies. Our expertise in working with human, veterinary, and mosquito vector systems allows us to approach human disease from a unified health perspective and adapt our methods to the system to provide the clearest understanding and the best solution to our research questions. Our current research focus includes 1) Engineering and developing AAV and lentivirus vectors for neuroscience and infectious disease research. 2) Establishing human brain organoids as a model to study the molecular mechanisms of psychiatric and other neurological disorders. 3) Developing Virus Reporter Particles (VRPs) and diagnostic ELISAs for fighting to emerge and re-emerging viral diseases.
