In my view, the strengths of CSNA lie in its tight-knit community and the specialized focus of its conferences. CSNA and its members provide a supportive environment that allows new researchers, new faculty, and graduate students to debate research ideas and develop as statisticians while learning from experts in the field. The specialized focus of the meetings allows for immersion in the current clustering/classification research that larger conferences could never provide. I would like to develop outreach programs that emphasize these qualities that should be particularly attractive to new statisticians. These programs could include, for example, increased advertising at other conferences or developing a young researchers invited session short-paper competition (for either new faculty or graduate students). In addition, the increase in interdisciplinary centers for applied statistics at universities world-wide should be an excellent opportunity to supplement the sessions of methodological talks with sessions focusing on specific applications of clustering and classification. These sessions might be attractive to those pursuing applied careers and could potentially increase both attendance and the participation of other related fields. My experience with CSNA as a graduate student and then as a young faculty member has been exceedingly positive; my focus will be on continuing to maintain the closeness of the community while extending invitations to new members in both statistics and related disciplines.

CSNA is in a membership crisis. Without a quick and significant increase in members we face the likelihood of folding as an organization. This is in many ways inconceivable to me considering how cluster and classification is used in so many disciplines. My focus as President-elect and President will be on coming up with ways of increasing and diversifying membership working with members and the board to develop a new focus in CSNA that will attract a broader membership class. CSNA was and should be again the focal point for anyone in any discipline doing applied, methodology, and/or theoretical work in cluster and classification.

To increase membership in CSNA from the behavioral and social sciences, it is important that procedures are shown to be relevant to commonly asked problems. To date, my research agenda has been to show how many of the more exploratory techniques used by CSNA members are at least as relevant as--if not preferable-- to more comman analytic strategies. I hope to continue to publish research in highly-visible quantitative psychology outlets that promotes those goals.
