Dr. Katz’s Research

It has been my great interest to investigate several of the rheumatic diseases. I have particular interest in lupus and fibromyalgia, but I have also researched other disorders. I have conducted basic investigational studies (see my curriculum vitae), as well as clinical research into new medications for the treatment of rheumatic diseases.

Below, you’ll find information about some of my research.
