Currently, Dharmendra Pratap Singh is working as Raman-Charpak fellow under the mentorship of Prof. A. Daoudi at Unité de Dynamique et Structure des Matériaux Moléculaires, Université du Littoral Côte d'Opale, Dunkerque, France. Previously, he was a Senior Research Fellow (CSIR) in the department of Physics, Lucknow University, Lucknow (India). He completed his B.Sc. and M.Sc. degree from the Lucknow University and joined Liquid Crystal Research Lab in 2009 under the supervision of Dr. Rajiv Manohar. He has also worked as Junior and senior research fellow in DST funded project from 2009 to 2012. Presently, he is involved in the study of different aspects of Liquid Crystal dispersed with various nanomaterials (especially on quantum dots). He has also been awarded by Young Researcher in 2012 by Indian Liquid Crystal Society and SPIE early career award in ICAMP-2013 at Cambridge University, UK. He has also been awarded by prestigious Raman-Charpak fellowship, a doctoral student exchange program between India and France, in 2014.

The POM represents the change in optical texture of a LC material in chiral nematic phase after the dispersion of graphene oxide (GO). After the dispersion of GO, we observed few cobweb structure in the POM.The POM was taken at 115.5C. The picture width is 10 micrometers.
Jury comment: Dispersions of graphene oxide in LC phases are increasingly important in colloidal liquid crystal science. This is one of many images of GO in LC phases that we will see more frequently in the literature from now on.
