‘Facial Recognition’ for Cells

Computer vision has an important role to play in medical diagnostics. Building on a decade of work in the field, Professor Kevin Tsia recently deployed an AI-driven, ultra-fast imaging tool to speed up cancer diagnosis and, in a separate project, applied AI to decode the development of zebrafish from images and other data.

Personal Record

Wearable technology that tracks a person’s vitals and health indicators is not unusual nowadays, but engineering researchers have taken the tech a big step further for more accurate and complex personal monitoring.

Technology in the Courtroom

How do live broadcasts affect behaviour in the courtroom? What happens when judges use AI? And what can data analytics tell us about the factors that favour litigants in court? Professor John Liu has been investigating

Interactive Excavation

Developing 3D technology for archaeological digs improves the accuracy and efficiency of data gathering, and reduces the destructive element.

Seeing Red

The bright plumage of the parrot is one of its most distinctive features, and until recently how their unique red colouring was produced was a mystery. Using cutting-edge technology, biologists have now solved this centuries-old puzzle.

Lessons from the Deep

Fossil data has shown that over time deep-sea ecosystems have been affected by temperature changes and food input, raising questions about possible negative effects of intervention measures to mitigate against climate change.

Online, in Touch

A comprehensive international study undertaken by a team from HKUMed and including longitudinal studies on elderly people, found that internet use among adults over 50 years old is consistently associated with better mental health outcomes.

In the Blood

A remarkable new treatment for leukaemia, invented and developed at HKU, is chemo-free and has a 97 per cent success rate, offering new hope and less treatment trauma for patients.

The Challenges with Computer Vision

Allowing computers to identify, use and store visual images such as people’s faces, travel routes and medical scans, and to make decisions based on that, raises legal and ethical concerns. Professor Boris Babic explains.

Perfecting the Image

HKU’s Visual AI Lab is developing models to comprehend images from the real world and create new visual content in 2D, 3D and 4D in a more accurate, efficient, accessible and cheaper way than current commercial models.

Modelling Human Vision

Professor Andrew Luo’s work is deepening understanding about how the human brain processes and understands images, which has implications for the development of machine vision.

Computers Take the Wheel

The technology behind embodied AI and autonomous cars has made huge strides in recent times, helped in part by a system devised by HKU Professor Li Hongyang and his collaborators.

Smart Eyes on the Street

Streets, sidewalks and roads which constitute more than a quarter of the built-up land in most cities, should be designed for people, but urban planning has typically not incorporated human perspectives. With the aid of urban big imagery data and AI, Professor Qiu Waishan is helping to correct this.

More than a Feeling

Bioethicist Dr Zohar Lederman has been exploring the philosophical implications of the individual and social harm caused by loneliness, and practical solutions.

Relief for the Lonesome

HKU researchers have been investigating interventions to help alleviate loneliness among Hong Kong’s elderly.

A Slippery Slope to Depression

Professor Tatia Mei-chun Lee and her colleagues have been investigating brain activity to see how loneliness can tip people into depression and what might be done to mitigate the effects.

The Fear Factor

Professor Cora Lai Sau-wan of the School of Biomedical Sciences has deepened our understanding of where and how fear memories are stored in the brain – and shown how these memories could potentially be erased.

Hep to a Cure

World-leading hepatitis researcher, Professor Yuen Man-fung, has made serious inroads towards a cure for some hepatitis B patients. He is also working to get more people tested so they can seek treatment for this silent but harmful virus.

Maternal Instinct

Researchers from HKUMed have found that extending Hong Kong’s statutory paid maternity leave led to a significant improvement in maternal mental health. The findings have significant implications at a time when birth rates worldwide are falling and labour force shortages are a significant problem.

Invisible Engineers

New findings highlight the critical role of invertebrates in breaking down forest litter and thereby helping sustain carbon and nutrient cycling.

The Bigger Picture

Using an innovative combination of the Sentinel-2 satellite mission and its dynamic time-series capabilities, along with phenological observations, biological scientists have made a promising advancement in mapping plant functional traits from space.

Star Quality

Astrophysicists develop new proposals for studying the earliest stars in the universe, uncovering secrets of its origin and offering deeper insights into the incredible journey from the primordial cosmos to the world we live in today.

Pet Project

Four-legged robots have a problem. What happens when one of their legs breaks or stops operating? Research by Professor Lu Peng is providing a solution that is also taking these robots further along the path to being truly interactive.

When Foreign Governments Meddle in Elections

Both the US and Russia have strong track records of meddling in foreign elections, including each other’s. In a year when billions of people are voting, Professor Dov Levin offers a timely overview of the methods and consequences of such interventions.

Neighbourhood Effects

Evidence shows that urban density and planning can have direct effects on social isolation and loneliness. Therein could lie a solution, says urban scientist Professor Chinmoy Sarkar.

A Measure of the Problem

HKU scholars have been investigating the effects of loneliness and social isolation in different cultures and the possibility of having a universal framework to identify people at risk.
