Our Mission

Our Research

We conduct research in fetal MCG and in fetal, neonatal, and adult MEG. Research training is one of the primary missions of the lab. Research projects are carried out by the lab’s staff and graduate students, in collaboration with investigators from several other UW-Madison departments and other institutions. Our research has been supported by a number of research and training grants from the National Institutes of Health.

Technology We Use

Biomagnetic signals are extremely weak, but can be recorded using an exotic superconducting detector known as a SQUID (superconducting quantum interference device) magnetometer.

The recordings must be made within a special magnetically-shielded room because the signals are dwarfed by the ambient magnetic interference present in a typical laboratory or hospital environment.

These equipment are highly complex and expensive. In addition to magnetic shielding, we employ specialized signal processing techniques to attenuate environmental and biological interferences.
