Research Project: Rapid Urine Specimen Processor for Point-of-Care TB Diagnosis

Project Description: Tuberculosis (TB) is a leading cause of death with 10-million new infections per year. Existing point-of-care assays lack accuracy due to low biomarker concentration in infected patient urine. I am developing a rapid and power-free urine specimen processor to enable point-of-care TB testing in low-and-middle income countries.


What have you learned throughout your research project?

Throughout the research, I had the opportunity to connect with infectious disease experts, clinicians, rapid test manufacturers, global health non-profits and regulatory officials to hear patient stories and understand the perspectives of stakeholders outside of the engineering field. By understanding the challenges faced by underserved populations in high-endemic countries and the dynamic relationships among stakeholders that are behind the fundamental global health barriers, I learned to develop accessible engineering solutions with heavy consideration of usability and clinical diagnostic workflow, to include features beyond the basic specifications of diagnostic accuracy and speed.
