FleXtal Lab

"One should be able to relate every physical property of a crystal to its underlying structure, if the structure-property correlation is established by carefully investigating each and every small structural factor,
i.e. strength, spatial distribution and nature of interactions. The FleXtal Lab's motivation is to make mechanical behavior of organic single crystals predictable and designable by using Crystal Engineering approach."

Dr. C Malla Reddy did his Ph.D. in Supramolecular Chemistry & Crystal engineering from the University of Hyderabad in 2006. There after he continued his research as a post-doctoral fellow at Karlsruhe Institute of Technology, Germany, 2007-2008. Immediately he moved to Indian Institute of Science Education and Research (IISER) Kolkata as an assistant professor in department of chemical sciences. In 2014 he has been promoted to associate professor. Then In 2019 he has been promoted to professor. For the Year 2014-2015, he has been awarded with prestigious Swarna Jayanti fellowship by Department of science and technology, Government of India.
Research Areas: Crystal Engineering & Supramolecular Chemistry, Self-healing Crystals, Flexible Functional Materials, Solid-State Pharmaceutical Chemistry (Tabletability), Structure-Mechanical Property Relationship.
