Judge, NYAS JSHS Competition: The Metro NYC Junior Science and Humanities Symposium (JSHS) provides a forum for High School students to present the results of their original research in the fields of science, technology, engineering and mathematics. 75 semi-finalists are invited to give ten minute oral presentations, based both on their performance at the NYC Science & Engineering Fair and the quality of their submitted research paper. Five finalists are awarded an expense-paid trip to the National Symposium where the regional 1st, 2nd and 3rd place finishers receive tuition scholarship awards.

International Atomic Energy Agency (IAEA) Technical Co-Operation Expert, World: IAEA specialists are a key element in the technical cooperation programme (TCP) and assist developing Member States to achieve self-reliance in numerous scientific and technological fields. Specific tasks are defined by the scope and objectives of the individual projects within the TCP. Typically, expert services include provision of advice to counterparts in the field, lecturing at training courses, and contributions to meeting/workshops. Technical Co-Operation experts possess sophisticated scientific and technical knowledge, and have the ability to share it effectively with others.
U.S. Director; Ukrainian American Chernobyl Ocular Study (UACOS), Ukraine: The Chernobyl nuclear reactor accident in 1986 and resultant explosion and fire caused radioactive contamination of large areas of Belarus and Ukraine. More than 600,000 individuals (Liquidators) were involved in clean-up and maintenance activities at the site. Many thousands were exposed to low doses of ionizing radiation. The Ukrainian American Chernobyl Ocular Study (UACOS) was established in 1996 to monitor the effects of this radiation exposure on the eyes of clean-up workers. Among eye tissue, the lens is most radiosensitive. Time and dose dependent development of posterior subcapsular cataracts (psc) following radiation exposure is well established as a marker of radiosensitivity. The goals of the UACOS are to monitor development of psc in a subset of the Liquidator population that undergoes periodic health and ophthalmological examinations and for whom there is good bio-dosimetry data associated with the clean-up efforts. In particular, this multi-decade, longitudinal study measures radiation cataract incidence, non-subjectively grades and records lens opacification and, in cases where cataracts are surgically removed, stores lens capsule-epithelial fragments for biochemical and molecular biological analysis. To date, findings from this study, and others, have helped lead to an up to 7-fold lowering of the recommended eye exposure threshold and have called into question the prevailing view of radiation cataract as a rather high dose deterministic event.
ICRP Task Group on Tissue Reactions and Non-Cancer Effects of Radiation, Committee 1: The International Commission on Radiological Protection (ICRP), a multi-national, independent network of specialists in various fields of radiological protection, provides recommendations and guidance on all aspects of protection against ionizing radiation to the general public and to governmental regulatory bodies and agencies. Its reports are published by Elsevier in the "Annals of the ICRP". The ICRP uses Task Groups of specialists (performing defined tasks) and Working Parties (developing ideas) to prepare its reports. At any one time, about one hundred scientists are actively involved in the work of the ICRP.
