Dr. Toma’s Research Interests

Selection for radiation resistance 

In collaboration with Dr. Andrew Roberts in the Physics Department of MNSU, we are studying the long term effects of gamma radiation exposure to Drosophila melanogaster through selection for increased levels of antioxidants. Antioxidants are produced by organisms to counter harmful oxidants produced by radiation exposure. Such oxidants are the principle cause of cellular damage caused by radiation. By exposing flies from egg - adult to gamma radiation, and breeding the adults together and repeating this over many generations, we can test the inherited response of flies to long-term exposure to radiation. Such work allows us to ascertain the degree to which effects from radiation are inherited and accumulate from generation to generation, and may provide insights into how organisms deal with such environmental stressors. 

 

Interface of science/philosophy/religion 

Over the years I have become increasingly interested in questions of science/philosophy/religion. This had lead to the publication of my first book – dealing with all three topics, entitled Vestige of Eden, Image of Eternity: Common Experience, the Hierarchy of Being and Modern Science. I am presently in the process of writing two more books.
