Bernstein

Jonine L. Bernstein

Bernstein

is an Attending Epidemiologist at the Memorial Sloan-Kettering Cancer Center (MSKCC) in New York City. Her core research focus is on breast cancer and gliomas and on understanding cancer risk and progression in order to identify those at highest risk because of gene carrier status, environmental exposures, or a combination of both. Dr. Bernstein is the Principle Investigator of the National Cancer Institute (NCI)-funded international 24-center Women's Environmental Cancer Radiation and Epidemiologic (WECARE) Study which was specifically designed to examine the interaction of radiation exposure and genetic predisposition in breast cancer, especially radiation-associated contralateral breast cancer (CBC) among 3,700 women with CBC and unilateral breast cancer.

The WECARE Study has served as the source population for studies of candidate genes such as BRCA1, BRCA2, CHEK2, and ATM, candidate gene pathways of DNA damage response involved in radiation-induced double-strand break repair—ATM, CHEK2, P53 binding protein (53BPI), and MDC1, Mre11, Rad50, and Nbs1 (e.g., MRN nuclease complex), a genome-wide association study, and most recently mammographic density. The global hypothesis across these studies is that women who carry certain types of mutations will be more susceptible to breast cancer than noncarriers, and possibly to radiation-associated breast cancer. Dr. Bernstein currently serves as a member of the Board of Directors of the American College of Epidemiology, the External Advisory group for the NCI-sponsored Breast Cancer Family Registry, the National Council on Radiation Protection and Measurements, and most recently the NCI Board of Scientific Counselors-Clinical Sciences and Epidemiology.

For the past two years, she has served on the Organizing Committee of the American Statistical Association Conference on Radiation and Health (2012 and 2014 meetings), and was Co-Chair of the Third North American Congress of Epidemiology, held in June 2011 for which she was honored by the 2012 ACE Award for Leadership and Service in Epidemiology. Dr. Bernstein holds a PhD in Epidemiology from Yale University, an MS in Applied Biometry from the University of Southern California, and an AB from Brown University. Before joining the faculty at MSKCC, she was Deputy Director of the Division of Epidemiology at Mount Sinai School of Medicine.

Responsible for each area is a committee chaired by a Scientific Vice President. These scientific program area committees are charged with evaluating the need for new NCRP work in the area and formulating their recommendations on the scope of the proposed new work and individuals who might be considered to chair any new report-writing committee that is constituted. These recommendations are submitted to the Board of Directors for action.

When the Board concludes that a new report-writing committee should be commissioned, the work begins with the selection of a committee chair, approval of committee membership based on consultation with the chair, and concurrence with the proposed scope of work prepared by the scientific program area committee and/or the chair.

Committee size varies considerably depending upon the subject area and the complexity of the undertaking. The usual size of scientific committees is 6 to 10 members.

A technical member of the NCRP Secretariat staff is assigned to work with and for each scientific committee. Committees also have access to consultants and advisors should these be needed in developing their work.

Following establishment of a scientific report-writing committee, it proceeds with its work which has as its endpoint the publication of a scientific report. This process often requires considerable effort with the time needed to complete a draft report varying appreciably from committee to committee.

The review process for draft reports is elaborate and comprehensive. It includes, first, review by a selected group of “critical reviewers.” Second, following modification on the basis of the comments of the critical reviewers, the report is submitted to the full Council membership and the organizations participating in the review process. Further modification on the basis of the comments received follows, with the goal of reaching an essentially unanimous acceptance of the material included in the report.

Scientific report-writing committees usually move into inactive status when they have completed their assigned tasks. This occasion is subsequent to publication of the pertinent scientific report. This retains, for a limited time, a source of advice and interpretation of published materials. Subsequently, a committee is usually disbanded.

Appointments to the membership of a scientific program area committee are governed by the following policy.

Scientific program area committee appointments, including those of chairmen, shall be considered to have been made at the time of the Board of Director’s meeting following the annual meeting which is closest to the time of actual appointment. Initial appointments to these standing scientific committees shall be for periods of two, four or six years, with the terms of approximately one-third of the membership expiring every two years. The chairman of the committee shall propose individuals for appointment and identify those proposed for initial two-year appointments, those proposed for initial four-year appointments and those proposed for initial six-year appointments. Subsequent appointments shall be for a period of six years. Retiring members may be proposed for reappointment. Proposed appointments (with biographical information) shall be submitted to the Executive Director prior to the Board of Directors’ meeting at which action on the proposed appointments is to be taken.
