Police said Garg turned himself in to University Police Station, reportedly after pressure built up on him by police and also his family members.
In her complaint, the research scholar had accused Garg of sexually harassing her during 2010-11 when she was pursuing her work under him at the city-based institution.
Police said the woman discontinued her research due to "uncomfortable situation" she was experiencing under her guide, that is Garg, and also for her marriage.
The couple then reached Gwalior and lodged a complaint with police who in turn registered an FIR against Garg under sections sections 354 (assault or criminal force to woman with intent to outrage her modesty) and 506-B (punishment for criminal intimidation) of IPC.
Garg was produced before a local court which remanded him two-day police custody.
