Benjamin B. Yellen, Assistant Professor of Mechanical Engineering and Materials Science and Center for Biologically Inspired Materials and Material Systems

Benjamin B. Yellen

The guiding principle of Dr. Yellen’s work is to investigate applications of electriciy and magnetism in medicine, energy, and the environment. One research focus is designing magnetic implants for drug delivery and medical imaging. Another research focus is developing nanoscale magnetic manipulation and tracking technology to observe the motion of colloidal particles immersed in ferrofluid (e.g., a suspension of 10nm iron oxide particles). A third research focus is the development of electrochemical apparatus to control local pH for various applications in bio-chemical array fabrication, electrolysis for generation of Hydrogen gas, and potentially other applications.
