**Meet the editor**

Dr. Annamalai Chandrasekaran received his Chemistry Doctorate degree in 1993 from the Indian Institute of Science in Bangalore, India. He has been working on single crystal X-ray crystallography for more than 20 years. He has been in charge of X-ray instrumentation for over 15 years and solved over 800 structures. Dr. A.Chandrasekaran has published more than 60 original

research articles. He is currently working as a Research Professor at the University of Massachusetts in Amherst, USA in the field of charge transport in organic materials. His current structural interests are focused on molecular packing and its relevance to the charge transport. He is a member of American Chemical Society and is also listed in World Directory of Crystallographers.
