Prof Dean Ho is currently Provost’s Chair Professor of Biomedical Engineering and Pharmacology, and Director of the N.1 Institute for Health (N.1) at the National University of Singapore.

Prof Ho and collaborators successfully developed and validated CURATE.AI, a powerful artificial intelligence technology platform based on the field of Phenotypic Personalized Medicine (PPM) to optimize clinical efficacy and safety for several combination therapy indications. He co-led the first in-human trial to personalize and optimize combination therapy for the entire duration of care, an unprecedented achievement. Specifically, his team partnered with leading surgeons to dynamically administer immunosuppressive therapies to prevent liver transplant rejection using CURATE.AI. CURATE.AI-treated patients dramatically outperformed control arm patients across every metric of comparison and were discharged nearly one month earlier compared to control patients (Science Translational Medicine, 2016). He also pioneered the development of nanodiamond platforms for the marked enhancement of efficacy and safety of drug delivery and imaging (Science Translational Medicine, 2011, 2013). Recently, Prof Ho initiated a first in-human clinical trial to validate a nanodiamond-biomaterial device for wound healing applications. Currently, Prof Ho is co-leading multiple oncologic combination therapy studies to dynamically modulate multi-drug regimens with CURATE.AI. These trials have resulted in completely halted disease progression and durable patient responses that far outperformed standard of care approaches.

Prof Ho is an elected member of the US National Academy of Inventors (NAI), and has appeared on the National Geographic Channel Program “Known Universe” to discuss his discoveries in nanodiamond drug delivery and imaging. His discoveries have been featured on CNN, The Economist, Forbes, Washington Post, NPR and other international news outlets. Prof Ho has served as the President of the Board of Directors of the Society for Laboratory Automation and Screening (SLAS), a 26,000+ member global drug development organization comprised of senior executives from the pharmaceutical and medical device sectors, as well as academic visionaries.

Selective activation of individual neurons is a cornerstone of our modern understanding of how brain activity relates to cognitive processes, such as perception, attention, memory and decision making. However, understanding neuronal activity in the context of other brain cells (i.e. networks of neurons) is essential to achieve a deeper understanding of brain function. In our lab we record the activity of dozens of neurons simultaneously while animals perform complex behavioral tasks. The goal is to understand information processing in networks of neurons distributed in multiple brain regions.

Representing a major paradigm shift from open surgery, minimally invasive surgery (MIS) assisted by robotics and sensing is emerging by accessing the surgical targets via either keyholes or natural orifices. It is challenging to accomplish delicate manipulations due to the constraints imposed by the mode of access, confined workspace, complicated surgical structures and the limited available technologies, particularly in terms of endoluminal curvilinear targeting and curvilinear guidance. Addressing the aforementioned challenges and aiming at the next generation of intelligent and flexible minimally invasive robots, my group focus on intelligent biorobotics research in compliant robotic system development, modeling & control, flexible sensing, human-robot interaction and intelligent navigation, tackling fundamental and technical challenges mainly in the context of medical applications. With the convergence of compliant and flexible robotics, sensing, and mechatronics, we bring the possibility of more curvilinear, adaptive, compact, nonintrusive, and intelligent assistance.

Our group aims to develop core platform technologies that enables massive integration of artificial sensory systems that surpass the human equivalent. Nature ensures survival by endowing complex living organisms with distinct skin sensors that have very high complexity. These structures enable skin sensors, for example, to be highly strain sensitive, and communicate in real time pertinent environment information. Endowing artificial systems with cutting-edge hapto-tactile capabilities could impact several areas such as next generation human-like robotic assistants, immersive virtual reality, smarter human-machine interfaces, wearable healthcare technologies and life-like prosthetics.

The Micro-Tissue Engineering Lab focuses on integrating patient-derived or human stem cells with micro-technologies to engineer human tissue equivalents that can model higher-order biological processes involving multiple cell types, and are scalable for drug testing applications. My approach is to drive technological development that are anchored by clinically relevant human diseases involving interactions between multiple tissues, such as developmental diseases and cancer.

Our research program is focused on two areas: neural coding and neuroprostheses. In the area of neural coding, we are interested in understanding how large populations of neurons in animal models encode and represent information. Our current focus areas are the role of neuronal populations in the prefrontal cortex in working memory and the role of neuronal populations in the hippocampal formation in spatial representations. In the area of neuroprostheses, we are interested in developing implantable systems that are capable of interfacing with the central and peripheral nervous system to monitor, modulate, and restore physiological functions. The areas we work on include electrodes, microchips, wireless power and data transfer, signal processing and decoding, and acute and chronic in vivo small and large animal testing.

There is a deluge of data across many scientific disciplines. Future scientific breakthroughs will rely on algorithms to explore these massive data. Our group develops machine learning algorithms to automatically generate scientific discoveries from large-scale datasets comprising thousands of subjects with brain magnetic resonance imaging (MRI), behavioral, genetic and other physiological measures. By exploring large multi-modal datasets, we seek to discover fundamental principles of brain network organization, how brain networks are organized to support cognition and how brain networks are disrupted in mental disorders.
