With healthcare costs rising globally, scientist Dean Ho is focusing his efforts on harnessing AI for personalised healthcare and biohacking
In a year where artificial intelligence (AI) is the buzzword, many of us have started experimenting with generative AI, working out how we can use it as a tool to increase productivity. For instance, generative text tools such as ChatGPT might provide the nudge needed to to get one’s creative juices flowing, while text‐to‐image platforms such as Midjourney and Dall‑E produce pictures in a fraction of the time needed to create one from scratch.
But Dean Ho, the recipient of the Tatler Hero Award in 2022, is already light years ahead in envisioning how AI could be used for a greater purpose. In his view, the way an individual engages with and prompts these programs could potentially be used to track their cognitive capabilities, creating opportunities for early intervention and, if necessary, treatment for cognitive decline.
“Beyond people using it to write their homework for them and stuff like that, I think ChatGPT could be used as a diagnostic where, over time, when people engage with chat tools, you can monitor symptoms such as cognitive decline,” says the the director of the Institute for Digital Medicine (WisDM) and the N.1 Institute for Health. “When used with discipline and by following certain best practices, things such as ChatGPT are potentially huge enablers.”

Indeed, he has made it his calling to do more with AI in digital medicine. The provost’s chair professor and head of the Department of Biomedical Engineering at the National University of Singapore’s College of Design and Engineering, who is also a 2019 Gen.T honouree, has been harnessing this technology to innovate personalised healthcare treatments in fields ranging from oncology to digital therapeutics and infectious diseases.
Ho moved to Singapore from the US in 2018 to helm the N.1 Institute for Health. Among other innovations, the team, in collaboration with doctors from the National University Cancer Institute, Singapore (NCIS), has developed Curate.AI, a tool that identifies and better allows doctors to provide personalised doses of medication for individual patients. “By using our platform Curate.AI, instead of defaulting patients to solely receiving the highest drug doses, we place the individual on a regimen that is within a safe range to strategically sample a little bit of data. We then use AI on this data to dynamically guide their drug dosing and medical care,” Ho says. Curate.AI’s treatment programme is currently undergoing human clinical trials.
What is groundbreaking about this research is that instead of relying on big data gathered from large numbers of people to train traditional AI algorithms, the platform is able to simply use just an individual’s own information to create a dynamic personalised treatment plan. Such treatments could include using different medicines to what is traditionally used, a combination of medications that was previously not considered, or even a lower dose than what is currently being used.
The results have been promising and could herald a disruption in the way many diseases, from cancer to liver disease and more, are treated. The team is currently collaborating on a trial with NCIS on how to use the technology to design optimal combinations of drugs for different types of brain cancer. (During the pandemic, Ho also worked to develop novel treatments for Covid‐19 with the help of IDentif.AI, another platform the team created.)
