Research Description

My main research interest is on the biological effects of nonionizing radiation, from extremely-low-frequency to radiofrequency electromagnetic fields. Research end points cover molecular biology, neurochemistry, and behavior. The main goals of the research are to understand the mechanism of interaction between electromagnetic fields and biological systems and to correlate biological changes with energy absorption in the body. The data would be useful in the setting of electromagnetic field exposure standards for humans. This area of research has gained public attention in recent years because of the increased use of electric power and radiofrequency energy. In the case of radiofrequency radiation, the tremendous increase in the use of cellular telephone and wireless communication systems have raised concern on the possible health effects of the radiation.

Another area of my research is to investigate the use of electromagnetic fields for the treatment of various diseases. We are exploring the use of low frequency magnetic fields for the treatment of malaria. Other related projects include use of magnetic fields for cancer treatment.

Another of research is to investigate the use of the compound artemisinin and its analogs for cancer treatment and prevention. New relating synthetic compounds have been synthesized and are being tested in our laboratory. These compounds have very high potency and selectivity in killing cancer cells and tumors in animals.
