Dr. Debabrata Patra

Associate Professor (Scientist-E)

Our lab work on at the interface of organic and physical chemistry. Currently we are focusing on (i) Self-powered supramolecular assembly (ii) Self-powered enzyme biosensors for lab-on-a-chip based detection (iii) Self-assembly at liquid-liquid interface (iv) Macroscopic self-assembly. 

We have multiple openings (UGC/CSIR JRF; DST-CRG project funded)  in our research group. 
Background in chemistry (organic/inorganic/physical) or biotechnology will be a perfect fit for our research group.
Interested candidates may contact me at patra@inst.ac.in for further query.
