STEM
Lightning-fast Internet, super-safe med-tech
Harrison Lees
PhD candidate in applied electromagneticsImagine if we could all access home Internet speeds around 1,000 times faster than currently possible. Or have biomedical images taken that show everything an X-ray does, but with zero risk of tissue damage.
These are just two of the incredible potential outcomes that Harrison’s PhD research could deliver. He’s leading development of a tiny, all-silicon integrated circuit platform that will be the world’s lowest-loss broadband terahertz waveguide—enabling humanity to harness the remarkable properties of terahertz radiation.
Harrison’s work has already attracted R&D partners in the defence, medical, and agricultural industries, and he couldn’t be happier. “The process of seeing a system you conceived, designed and tested come to life is hugely satisfying,” he says.

Health
Reducing chronic pain for millions
Diksha Sirohi
PhD candidate in digital healthEndometriosis is a big problem; it causes chronic, severe pain for 11% of natal females globally. And when that pain hits, everyday life becomes all but impossible.
Diksha—through her PhD research—is making a difference. In consultation with the Australian endometriosis community, she has co-created the world’s first evidence-based endometriosis digital health platform: EndoZone.
Crucially, EndoZone's online tools will enable early diagnosis, which can significantly reduce future complications and minimise the impact on the quality of life. “I love being able to support and empower the endo community,” says Diksha. “It’s incredibly rewarding.”

Energy
Making green power cheaper in the electricity grid
Sahand Karimi Arpanahi
PhD candidate in power systems engineeringSahand’s PhD research could help make possible a critical step in Australia’s efforts to achieve Net Zero target: cost-effectively adding higher amounts of clean, renewable energy sources to the grid.
He’s developing novel methods for battery storage sizing and operation that reduce the unpredictable fluctuations in solar and wind power generation, enabling higher profit for renewable power stations and lower households’ electricity costs.
The CSIRO is now closely involved, and AEMO’s also interested. “I’ve really enjoyed the University’s research-focused environment,” says Sahand, “and my supervisors’ focus on research quality, rather than quantity.”

Defence and space
Predicting orbiting objects’ paths
Chee Kheng Chng
PhD candidate in machine learningThings are getting pretty crowded up there; the US Space Command now tracks almost 35,000 objects in low Earth orbit. So in the interests of keeping valuable items safe, such as satellites, it pays to be able to accurately calculate their path, as quickly and easily as possible.
Through his PhD project Al4SPACE, Chee Keng is finding an answer. With support from defence prime Lockheed Martin, he’s developing a novel algorithm that can accurately estimate a satellite’s orbit simply by evaluating a long-exposure digital image of it.
Chee Keng is also exploring the use of various techniques to help identify distant stars, and reconstruct the shape of objects in space. “I love learning new stuff,” he says. “The privilege of being able to sit down and ponder every day is something I don’t take for granted.”

Agriculture, food and wine
Making sustainable agriculture attainable
Sara Qanti
PhD candidate investigating gender in agricultureGovernment policy has a critical role to play in soil and water conservation. But its impact can be minimal if gender’s influence on farming household decision-making isn’t well understood.
Sara’s PhD research is filling that gap. She’s analysing the decision-making process within smallholder agricultural households in rural Indonesia—and particularly women’s role in that process—to gauge how it affects the adoption of conservation practices.
Sara’s work is part of an umbrella project funded by the Australian Centre for International Agricultural Research, and also involves Indonesia’s Ministry of Agriculture, and non-government Indonesian research agencies. “I’m loving learning new things outside my comfort zone,” she says, “and meeting new people from all kinds of backgrounds.”
