Rinku Thomas-picturePostdoctoral associate, Masdar Institute of Science and Technology, , Abu Dhabi, UAE
Ph.D. Polymer Technology, Cochin University of Science and Technology [CUSAT], Kerala, India, 2000
M.Sc. [Chemistry- Polymer Science], Mahatma Gandhi University, Kerala, India, 2000
B.Sc. Chemistry, Mahatma Gandhi University, Kerala, India, 1997

 

Dr. Rinku Thomas joined Dr. Arafat’s Research group at Masdar in September 2011, under the department of Water and Environmental Engineering. She worked on the preparation and characterization of novel membranes for the Membrane Distillation process.

At Masdar, Dr. Rinku’s research primarily focused on morphology changes induced as a characteristic of fabrication parameters. She also investigated the role of novel additives and process parameters in pore formation and also their influence on key membrane parameters such as the morphology, hydrophobicity, Liquid entry Pressure [LEP] and the pore size distribution [PSD], together with many other parameters such as mechanical strength and crystallinity. The final goal of the study was to identify and bring to practical application suitable membranes which would stand the intricate demands of Membrane Distillation.

Dr. Rinku received her bachelor in Chemistry (1997) from Mahatma Gandhi University, Kerala State, India and then completed her Master in Polymer Chemistry from the Mahatma Gandhi University, Kerala State, India in 2000, where she investigated the Hydrogels for water Purification from nanosized- impurities. She then moved to CUSAT to pursue a Ph.D. program in Polymer Science and Engineering, working on conducting polymers for Microwave applications.

Dr. Rinku’s doctoral research focused on synthesis chemistry of conducting polymer for microwave application. Different classes of conducting polymers such as Polyaniline, Polythiophene and polypyrrole were successfully synthesised as Inter penetrating networks and with variation in morphology due to the additions of various doping agents.
