Tamara Loos is currently writing a book that seeks to integrate emotions, affect and violence into history generally and Thai history in particular. It asks how we can historicize emotions and incorporate them in historical studies without instrumentalizing them. This project utilizes court cases, newspapers sources, personal letters, and novels written since the turn of the 20th century in Thailand.

Her first book, /Subject Siam: Family, Law, and Colonial Modernity in Thailand/ considered Siam's place as a colonized and colonizing power in Southeast Asia. It detailed the forced incorporation of Malay Muslim areas into Siam, and revealed the gendered core of Thailand's modern legal system. It is among the first historical works to integrate thoroughly both the Malay Muslim south and gender into Thai history. Her articles include studies of sex and politics, transnational sexualities, comparative law, sodomy, the family, suffrage, intimate violence, rape and notions of liberty in Thailand.
