Md. Azahar Ali is a postdoctoral candidate in the Mechanical Engineering Department at Carnegie Mellon University. His current research focuses on 3D printed biosensors for pathogens and biomarker sensing. Earlier, he was a postdoctoral researcher in the Department of Electrical and Computer Engineering at Iowa State University, where he received a Postdoctoral Scholar Research Excellence Award in 2019 for developing field-deployable MEMS-based plant/soil sensors to map nitrate dynamics. He obtained his Ph.D. from the Indian Institute of Technology in 2014. He has co-authored 60 peer-reviewed papers in the areas of biomedical sensors in reputable journals, a textbook, book chapters, and many conference papers, and has filed five patents. He is actively engaged in the area of microfluidics, bioMEMS, and 3D-printed biosensors for healthcare monitoring.
