Manjula Devak, a PhD student in water resources, was found hanging at her flat around 7.38 PM yesterday.
While no suicide note was found from the flat, Devak's family alleged that her in-laws were not in favour of her pursuing higher studies, police said.
They also accused her in-laws of demanding dowry, police added.
Her family members have recorded their statement in front of a sub-divisional magistrate.
Davak had got married in 2013 and her husband and in-laws stay in Bhopal.
