Dina C. Merrer joined the Barnard chemistry department in 2001.  A physical organic chemist, Professor Merrer and her undergraduate research group study the mechanisms of intermolecular carbene additions to strained cyclic compounds and the impact of reaction dynamics on these mechanisms.  They use a combination of experimental and computational techniques to elucidate reaction pathways that exhibit non-traditional behavior. The Merrer group has been supported continuously by the National Science Foundation or the Petroleum Research Fund of the American Chemical Society or Research Corporation since starting at Barnard.

Merrer has mentored 45 undergraduate research students at Barnard.  Her students have co-authored several research papers; students’ names are noted below.  In addition, her students have presented their work at national meetings of the American Chemical Society and over two-thirds have gone on to Ph.D., M.D./Ph.D., and M.D. programs in the chemical and biological sciences or onto careers in the chemical sciences.

Merrer has served as the co-chair of the 2016 Reaction Mechanisms Conference (RMC) during which she co-organized a workshop on increasing diversity and inclusion in chemistry.  She has also served on the RMC Governing Board (2010-2016).  Merrer was the guest editor of the Journal of Physical Organic Chemistry special issue on Reactive Intermediates and Unusual Molecules in 2011 and contributed a chapter on Dynamics in Carbene Reactions in Contemporary Carbene Chemistry in 2012.

Merrer teaches courses in organic chemistry, including Organic Chemistry I and II, and Advanced Organic Chemistry.  She is currently co-chair of Barnard's Self-Study for reaccreditation by the Middle States Commission on Higher Education.  Formerly, Merrer has served as chair of the Chemistry Department and as a member on Barnard's Committee on Appointments, Tenure, and Promotion; Faculty Governance and Procedures Committee;  Faculty Finance and Resources Committee; Committee on Instruction; and President's Working Group on Diversity and Inclusion.
