Simarjit has been a humanitarian activist for the past fourteen years helping widows and torture survivors of 1984-1994 through TARAN, using over a decade of her salary, savings and book revenue. She researched with the CCDP, Committee For Disappearances Punjab, finding survivors who remained unhelped and unknown beyond established findings. She set up 'the first medical network for all survivors in this region of impunity...' (Justice Ajit Singh Bains, PHRO) in 2002 inspired by Dr. Vincent Iaccopino, Physicians for Human Rights USA and brave field researchers like Harshinder Singh, Amrik Singh, N. Singh, CCDP. She was nominated for the World Sikh Awards, 2013, for her work in charity despite being field based in Punjab for years and relatively unknown in the West.
Simarjit has spoken several times in British parliamentary seminars, at UN Women, Vrindavan, 2014, directly asking people in authority in India and Geneva- What have they done for the plight of torture survivors and why has a humanitarian route not been enabled in post conflict Punjab? There are still thousands of severely neglected cases of survivors.
Simarjit has been a big advocate for the importance of art in understanding the sikh genocide and the importance of a renaissance in sikh literature in English.
