Докторант из бедного района Малайзии защитила диссертацию по очистке воды в 27 лет

Boiling could have removed some, but not all, of the risks. Heavy metals and organic pollutants stayed behind, invisible in a glass of water that looked perfectly clean. That quiet, nagging worry followed Dr M Yamunathevi into adulthood. “There must be a better way to treat this water,” she remembers telling herself. That single question, asked by a child in an estate with no laboratory in sight, would eventually carry her to a doctorate in Bioscience, specialising in Environmental Biotechnology, from Universiti Teknologi Malaysia (UTM). She qualified for her PhD in August 2025 at the age of 27. Her doctoral research focused on wastewater treatment using bacterial-nanocellulose-based technology, a sustainable approach to removing pollutants such as copper from water. It is a long way, technically, from the untreated river water of her childhood. Yet the line between the two is direct. “Growing up in the estate made environmental issues feel very real to me, particularly the importance of safe water,” she says. “I carried both my father’s values and my community’s experiences into the laboratory.” Yamunathevi is the first in her family, and among the first from the Bukit Jalil Estate community, to earn a doctorate. A childhood shaped by the estate Her father, S Mathivanan, remembers a childhood built around routine and modesty. He attended nursery from the age of three, then school from seven, followed by tuition classes that cost just RM2 a session with a teacher named Balan near the Bukit Jalil shops. In between, there was gardening with his own father, football with friends and prayer. It was a simple life, he says, but one thread ran through it without exception: his family’s insistence that education mattered above almost everything else. That belief travelled with him into fatherhood. Mathivanan worked overtime whenever he could, made sure his children reached tuition on time even when it meant rushing back to work afterwards, and quietly carried the financial weight of ensuring his daughter had the same academic support as her three brothers. He calls these things ordinary responsibilities. His daughter calls them sacrifices she is determined to repay. “I always felt that one of the ways I could repay him was by making him proud,” Yamunathevi says. “It was never only about getting a PhD or having a title. I wanted him to be able to look at what I have achieved and feel that all those years of hard work were worth it.” The loneliness of being first Being the first in her family to attempt a doctoral study meant Yamunathevi had no map to follow. Her family could encourage her, she says, but they could not fully understand a world of failed experiments, confusing data, endless revisions and deadlines. There were long stretches when she questioned whether she was making any progress at all. “I did not need to have everything figured out at once,” she says now. “I just needed to keep moving forward.” Finishing her PhD at 27 demanded discipline that came at a cost. While friends her age were earning their first salaries, travelling and enjoying new freedom, she stayed in the laboratory. Experiments failed, sometimes again and again. There were tears, frustration and moments when she wondered whether she was capable of finishing at all. What kept her going, she says, was returning again and again to the reason she started. It was never about racing anyone else. It was about keeping a promise she had made to herself. A message beyond the laboratory Yamunathevi is careful to say her qualification carries a second purpose beyond the science itself. “I did not come from a family of academics. I did not grow up already knowing how the research world worked,” she says. “I simply had a goal, and I kept working towards it. If someone reads my story and thinks, ‘Maybe I can do this too,’ then I feel my journey has achieved something beyond the PhD itself.” To a young girl growing up in an estate today, her message is direct: Do not allow your background to decide the size of your dreams. You may not have all the resources or connections that other people have, but that does not mean you cannot achieve something extraordinary. Dream big. Be confident in yourself. Surround yourself with good people, stay positive and never give up on yourself. Her father offers his own version of that advice, aimed at other fathers in estate communities. Encourage your children to do well and aim high but never demotivate them or compare them with other students. Every child has a different journey. If we give our children education, discipline, encouragement and confidence, they can go much further than the world around them may expect. What comes next It has been a year since she completed her PhD, and Yamunathevi is now actively seeking employment, particularly as a lecturer at a public university, in line with her academic background and research expertise. She hopes the higher education ministry will soon offer her a posting where she can continue her research and begin teaching the next generation of scientists. For a young woman who once wondered whether a girl from an estate could belong in a laboratory, the answer now stands as her own life’s proof. For every B40 student and student from an estate community reading this, her story is not simply about a doctorate. It is a reminder that where you begin does not determine how far you can go; only how hard you are willing to work to get there.
