Travis Dietz and Dr. Ileana Pazos present at 2016 ICIP Meeting

icipgroupphotoThis past week, Prof. Al-Sheikhly, Dr. Dianne Poster, Dr. Ileana Pazos, and Travis Dietz attended the International Conference on Ionizing Processes at Brookhaven National Laboratory. At the conference Travis presented his work on uranium extraction and Dr. Pazos presented her work on nanogel synthesis in both poster and presentation formats. The conference focused on the impacts of science related to the fundamental chemical, physical, and biological effects induced by ionizing particles and photons, especially in relation to medicine and industry.
