Her research focuses on bioelectrochemistry, biomaterial engineering, nanotechnology for sensing, and therapeutic applications. Her 

research interest is healthcare monitoring by designing and fabricating of wearable and printed electrochemical and photo-electrochemical sensor, biochips and biosensors such as immunosensors, cytosensors, DNA and aptamer based biosensors etc. Her research mainly demonstrates development of bioelectronic systems and diagnostic assay using screen printed electrode, array electrode, enzyme-based and/or sandwich immunoassay, whole cell biosensors, ELISA and designing sensors based on organic electrochemical transistors.

Dr. Robabeh Motaghed Mazhabi worked with biosensor group of Professor Marco Mascini at Universita Degli Studi Di Firenze, Italy as visiting researcher in the field of electrochemical biosensor. She was postdoctoral fellow at Southeast University in the field of phtoelectrochemistry with involvement of the designing and fabrication of photoelectrochemical sensors and biosensors. Dr. Mazhabi was also carried out research in the field of cell biology, evaluating the cytotoxicity effect of nanoparticles on cancer cells during her stay at the International Academy of Optoelectronics, South China Normal University.
