Ashok Kumar works in the area of Biotechnology and Molecular biosensors. His major interests are in enzyme and DNA based biosensors. Presently, he is working on DNA based biosensors for detection of pathogenic bacteria causing meningitis, typhoid and rheumatic heart disease.
His group, in collaboration with researchers at other institutes, is working on an electrochemical DNA sensor for efficient detection of Neisseria meningitidis, the bacterium responsible for meningitis.
