Dr. Arya earned his B.Sc. (chemistry honors program) from St. Stephen's College, Delhi; and Ph.D. (Bioorganic Chemistry) from Northeastern University, Boston. After spending his postdoctoral years in the labs of Prof. T. C. Bruice (UC Santa Barbara), he joined the faculty at Clemson University. Dr. Arya is a recipient of a National Science Foundation CAREER Award(2002) and the ACS Horace S. Isbell Award of the Division of Carbohydrate Chemistry (2007). He has served as the Program Chair (2004-2008), Chair-Elect (2009-2010) and Chair (2010-2011) of the ACS Division of Carbohydrate Chemistry.

Research Interests

The long term interest of our lab lies in the understanding,Chemistry Photo Arya Profile
design, and discovery of new motifs for the molecular recognition of biological macromolecules. An example of current focus of the laboratory is to understand the features that differentiate B-form from A-form DNA and use this knowledge to discover and design molecules that can specifically recognize A-and B-form DNA. Results obtained are expected to lead to a new pharmacophore for major grooves of A and B-form-DNA recognition that can be further developed to obtain DNA specific molecules with higher
affinities and specificities. Minor groove recognition of DNA was driven by the structures of polyamide-DNA complexes solved during the 80s. We expect that a similar characterization of a major groove specific ligand will complete an important missing link in the goal of major groove DNA recognition by small molecules leading to the development of more sequence-specific and higher affinity molecules. Similar tools are being applied to the recognition of higher order DNA and RNA structures, such as triplexes and quadruplexes.

The laboratory is equipped to conduct synthesis, physical and structural studies of natural and designed conjugates that are capable of binding to nucleic acids and proteins. These studies are important to both fundamental understanding of macromolecule recognition and to drug development. Based on the information gained from fundamental studies of molecular recognition and supramolecular chemistry, new drug analogues can be synthesized to exhibit altered binding properties with desired biological effects. Ongoing projects combine areas of synthetic organic chemistry, physical organic chemistry, biochemistry, pharmacology, and molecular and cell biology. The interdisciplinary nature of these projects allows students to develop a strong basis for future research. The lab maintains active collaborations with biophysicists, oncologists and infectious disease experts.
