She obtained a doctorate degree in 2005 from the Institute of Genomics and Integrative Biology in New Delhi, India. She went to the University of Notre Dame in Indiana to join her husband, who had taken a faculty position there after finishing graduate school, said Professor Dave Severson, who runs the lab where she worked.

The lab studied how mosquitoes transmit diseases, and Chauhan focused on the transmission of dengue fever.

Chauhan worked in theUSFCenter for Biological Defense and Global Health Infectious Disease Research, which is housed at the USF Research Park on the south end of campus. The center was created after the Sept. 11, 2001, terrorist attacks to study bioterrorism and emerging infections.

Security is tighter throughout the research park because work is done there with private companies and the Department of Defense.
