Bio: Kaicheng’s interests are in techniques and devices for minimally invasive, endoscopic microscopy in living systems and patients, with a specialization in ultrahigh speed optical coherence tomography (OCT). His experience spans photonics and fiber optics, clinical gastroenterology and endoscopy, medical devices and robotics, and artificial intelligence for image interpretation. His vision is that cutting-edge photonics empowered by machine learning will enable instant microscopic analytics of living tissue at the molecular level and on the scale of entire organs, thereby enhancing the quality and coverage of real-time feedback to clinicians during procedures, and improving patient outcomes.
Born and bred in Singapore, Kaicheng is a Singapore National Research Foundation (NRF) Fellow, with substantial funding from the Singapore Government to pursue independent research and advance the country’s scientific and technological edge. He is also a recipient of the A*STAR scholarship, which generously supported many years of education in the United States, as well as the MIT Helen Carr Peake Research Prize and the American Gastroenterology Association Certificate of Recognition for Early Career Investigators for his development of minimally invasive upper endoscopy in awake patients, enabled by his micromotor tethered capsule endoscopic OCT imaging platform.
Kaicheng is the creator of a family of popular Twitter bots (in collaboration with subject matter experts) that use machine learning to automatically scrape and disseminate new research to the respective scientific communities. Check out @biophotonicat for research in biomedical photonics, @higgsinocat for dark matter physics (collab. with Hongwan Liu), and @electrochemicat (collab. with Edwin Khoo) for batteries and energy storage.
