Hazel Lockhart was born on the 12th of April, 1985, in the serene town of Launceston, Tasmania. The daughter of Dr. Marcus Lockhart, a prominent geneticist, and Dr. Evelyn Lockhart (née Thompson), a dedicated paediatrician, Hazel grew up in an intellectually stimulating environment. Her parents instilled in her a profound appreciation for science and a relentless curiosity about the natural world. She was the second of three children, with an older brother, Thomas, who pursued a career in environmental science, and a younger sister, Emily, who became an accomplished violinist.

From an early age, Hazel exhibited a remarkable aptitude for science. Her childhood was spent in a home filled with books, scientific journals, and lively discussions about the latest discoveries in genetics and medicine. Encouraged by her parents, Hazel often accompanied her father to his laboratory, where she developed a fascination for the intricate world of DNA and molecular biology. This early exposure to the scientific world laid the foundation for her future career in forensic science.

Hazel attended Launceston Grammar School, where she excelled in her studies, particularly in biology and chemistry. Her teachers recognised her potential and encouraged her to participate in various science fairs and competitions. She graduated with top honours in 2002 and was awarded a scholarship to study at the University of Sydney.

In 2004, Hazel began her undergraduate studies in Molecular Biology at the University of Sydney. She quickly distinguished herself as a dedicated and highly capable student, specialising in genetics and forensic science. Her honours thesis, "The Application of Mitochondrial DNA in Forensic Investigations," earned her widespread acclaim and set the stage for her future endeavours in forensic DNA analysis. She graduated with honours in 2007, ready to further her education and expertise.

Determined to pursue a career in forensic science, Hazel enrolled in the Master of Forensic Science programme at the University of New South Wales in 2008. Her dissertation, "Innovations in DNA Profiling and Their Impact on Forensic Casework," reflected her innovative approach and deep understanding of the field. During her time at university, Hazel formed lasting friendships with fellow students Clara Thompson and Lucas Ramirez, who would later become prominent figures in forensic science.

In 2010, Hazel began her professional career as a Junior Forensic Scientist with the New South Wales Police Forensic Services Group. Here, she honed her skills in DNA extraction and analysis, processing biological samples from crime scenes, and preparing detailed forensic reports. Her meticulous attention to detail and ability to think critically quickly earned her a reputation as a rising star in the field.

In 2012, Hazel joined the Australian Federal Police (AFP) Forensic Services as a Forensic Scientist in the DNA Analysis Unit. Her tenure at AFP was marked by significant contributions to high-profile cases and the implementation of new DNA profiling techniques. She played a crucial role in training junior scientists and collaborating with international forensic experts, further solidifying her expertise and reputation.

Seeking new challenges, Hazel relocated to Hobart in 2015 to join the Forensic Science Service Tasmania (FSST) as a Senior Forensic Scientist. In this role, she led forensic DNA investigations, specialising in complex and high-profile cases. One of her most notable contributions was her work on the investigation into Detective Sarah Lahey's death in 2018, where her comprehensive DNA analysis provided crucial evidence that helped piece together the events leading to the tragedy.

Outside of her professional life, Hazel is an avid hiker and enjoys exploring Tasmania's breathtaking landscapes. She is also passionate about music, a talent she inherited from her mother, and plays the piano in her spare time. Hazel is known for her love of reading, particularly mystery novels and historical fiction, which provide her with both relaxation and inspiration.

Hazel married Andrew Lockhart, an environmental engineer, in 2012. The couple shares a deep love for nature and a commitment to environmental conservation. They have two children, Angela, born in 2014, and Charles, born in 2017. The family often spends weekends hiking and camping in Tasmania's national parks, fostering a love for the outdoors in their children.

Throughout her career, Hazel Lockhart has been recognised for her expertise in forensic DNA analysis, her innovative approach to forensic science, and her unwavering commitment to uncovering the truth. Her contributions to the field have not only advanced forensic methodologies but also provided justice and closure in numerous complex cases. Hazel's dedication to her work and her family, combined with her passion for science and nature, continue to define her as a respected and influential figure in the forensic community.
