Gary Friedman’s interests are in applications of electrical and magnetic phenomena to medicine and biology. His recent work involved development of miniature coils for Nuclear Magnetic Resonance imaging of cells, magnetic manipulation and separation in lab-on-a-chip applications, cellular probing using carbon nanotubes, magnetically targeted drug delivery in cardiovascular and orthopedic applications. He has also initiated work on applications of non-thermal plasma in medicine.

Dr. Friedman's research in nanotechnology includes study of self-assembly of magnetic nano-particles and applications of magnetic nano-patterns and nano-particles to fabrication of biochemical sensors and sensor arrays. He is also developing miniature Nuclear Magnetic Resonance (NMR) sensors and systems.

Dr. Friedman's work in the area of Micro-Electro-Mechanical Systems (MEMS) includes micro-fluidic systems for delivery of liquid micro-drops and the use of liquid micro-drops for adaptive optical devices and switches. He is also actively involved in theoretical and numerical modeling of hysteresis related phenomena in complex systems such as magnetic particle assemblies and nano-structured magnetic materials
