Dr. Haezreena is a Criminologist and a Senior Lecturer at the Faculty of Law, University Malaya. She was called to the Malaysian Bar in 1997 and has extensive experience in civil and criminal litigation. Dr Haezreena is against all forms of violence, discrimination and oppression, and believes that communication is vital to achieving positive results. Her specialization includes; human trafficking, criminology, incarceration, gender, women's rights, terrorism and violent extremism, organised crimes, and criminal justice.

Dr. Haezreena obtained her PhD in Criminology from Victoria University of Wellington, New Zealand. She enjoys learning and contributing her ideas to the field of law and criminology. Dr Haezreena is guided by the works of Michael Foucalt who addresses the relationship between power and knowledge, and theorists such as Sandra Walklate and Nils Christie who believes that crime, offenders and victims are socially constructed. 

Her thesis entitled 'Sex Trafficking: Victimisation and Agency: The Experiences of Migrant Women in Malaysia' received high praise from international scholars for its orginality and novelty. Her research did not only bring women’s voices and lived experience to the forefront but also revealed the women’s outlooks, vulnerabilities, and aspirations in order to improve the treatment of victims of trafficking.

Dr Haezreena describes herself as a post-colonial theorist and a socio-legal scholar who thrives to uphold human rights and justice without fear or favour. Using her legal background and her criminological knowledge as her forefront, she strives to understand the fabrics of the society and make sense of the problems and dilemma faced by individuals from all walks of life. She is currently exploring the criminological theories that can be applied to terrorism, and the oscillation of victim to perpetrator to survivor. 

Dr Haezreena has written books on trafficking in persons which are now used as a source and reference for enforcement officers and protection officers, as well as researchers. She has also written numerous articles on the continuum of harm of trafficking, victim blaming, inequality, social justice issues, and gender disparities. Her works are often cited and referred to by local and international NGOs, and government agencies.
