S. No.	Name of the Project	Duration	Source of Funding	Amount of Funding (Rs)
1.	Ammonoid � Sequence � Magneto Stratigraphic integration in the Kachchh Jurassic, As Co-Investigator)	2009-2013	DST Sponsored Project (in collaboration with NGRI, Hyderabad)	35,30,400.00 (23,10,600.00 only as BHU Component)
2.	Bio and Sequence Stratigraphic Implications of Late Jurassic ammonoids in Spiti Himalaya, India. (As Co-Investigator)	2010-2013	CSIR Sponsored Project	4,65,750.00

1. The significant lasting contribution of the current research is the development of high resolution ammonoid based geological refinement in the Indian Jurassic of the order of 100,000 yrs. to 500,000 yrs. which equals the best of the world as also the best of the entire Indian shallow marine geological record. Multidisciplinary study (Ammonoid-Sequence-Magnetochronologic integration) in collaboration with NGRI is going on particularly in Jurassic of Kachchh .
