Devlina Das Pramanik


A Biotechnologist by education and Innovator by passion!.

Graduated  from Vellore Institute of Technology, Tamil Nadu, India. Completed my PhD in the area of adsorption kinetics for transition metal series (Zn and Ag). Awarded by RELX, Elsevier (Environmental Challenge 2015) for designing flocculation-desalination technology to convert sea water to drinking water (2016-17). Keen on product development. Worked on ‘Coagulation-Flocculation’ technology for 5 years and developed related patents on that. Awarded Biotechnology Ignition Grant by BIRAC, DBT, Govt of India with IKP Knowledge Park as the accelerator. Developed a product ‘Flocco’ during this tenure (2018-2019). Start-up enthusiast!

Keen on teaching! Served as an Assistant Professor, Department of Biotechnology, PSG College of Technology, Coimbatore, Tamil Nadu, India (June 2017-November 2019)

Subjects Taught- downstream Engineering, Analytical Instrumentation;

Courses Designed and taught (graduate and post graduate levels): Biopolymer technology
