Areas for Ph.D. Qualifying Exams

Sub-areas for Ph.D Qualifying Examination:

A:  Environmental and Microbial Biotechnology 
B:  Parasitology and Vector Biology
C:  Bio-informatics and Computational Biology
D:  Plant Biotechnology
E:  Human Diseases and Immunology
F:  Biochemistry  
G: Molecular Biology & r-DNA Technology
H: Animal Biotechnology 
 
General Note: The Senate of the Institute (160.02) has approved that Ph D qualifying examination will be conducted in two areas from the list of qualifying examination areas in the sub discipline of each department. Each student will choose two subareas; one of these must be the sub-discipline in which he/she proposes to undertake research after the consultation with his/her notional supervisor.
As per requirement, each subarea may have several sections with a total of 150/160 marks for theory and 50/40 marks for viva. The duration of each theory examination will be 3.0-4.0 hrs. Viva may be conducted separately for each sub area. A student will get a maximum of two attempts for clearing the qualifying examination (Ref clause 8.05-8.11 of academic regulation).
