Vaishnavi Pallapothu, Intern

Vaishnavi Pallapothu recently graduated from SOAS, University of London with an MA in International Studies and Diplomacy. She is passionate about foreign policy dynamics in the Indian and South Asian context, as it is often an underrepresented geography in global affairs. She is also very interested in the potential for feminist foreign policy to transform the field of international relations. Vaishnavi has experience in online community building and engagement through her work with World Pulse. She has worked on several gender-based international relations research projects. Her previous experience includes working with think-tanks and NGOs in India and the UK, including SCRAP Weapons, the Gender Security Project, the Chennai Centre for China Studies and the Red Elephant Foundation. The confluence of her previous experiences and her education led her to develop an interest in learning how policies translate and affect people on the ground, leading her to intern at the IRM. She is looking forward to learning about and acquiring skills relevant to bottom-up policy perspectives, grievance redress mechanisms and accountability of international organisations during her internship.
