Dmitriy Tipikin, Ph.D.

    Dmitriy Tipikin worked in the field of EPR technique and EPR applications for 30 years. During his career he applied EPR to investigation of radical pairs, EPR centers in humic acids, in melanin, in spin-labeled proteins, DNA, RNA. Developed quasi-optical bridges for high-field EPR, instrumentation and resonators for low-field EPR and high-field EPR.

The sphere of interests:

   He is interested in development of new technological approaches in low-field EPR, engineering of devices for imaging of small animals and biological tissues.
