Mathews, Sunish


Personal profile


Dr. Sunish Mathews is Lecturer in Medical Engineering and Technology.
He completed Ph.D. at the Technological University (TU) Dublin, Ireland, and continued as a postdoctoral researcher.

Dr. Mathews joined University College London (UCL) as a Research Associate in the Medical Physics and Biomedical Engineering Department. He was part of the Photoacoustic Imaging Group and was closely associated with the Wellcome/EPSRC Centre for Interventional and Surgical Sciences (WEISS). During his tenure at UCL, he also served as a part-time Senior Sensor Engineer at the start-up Echopoint Medical Ltd.

Dr. Mathews hails from the picturesque town of Kottayam in Kerala, India. He earned his Master’s degree in Applied Physics from CMS College, Kottayam, affiliated with Mahatma Gandhi University in Kerala.
Following a teaching career primarily at the pre-university level, he worked at the Indian Institute of Technology (IIT) Guwahati as a Research Assistant, before starting his PhD programme in Dublin.


Dr. Mathew's research focusses on developing innovative fibre optic sensing systems to advance diagnostic, testing, imaging, and therapeutic techniques in interventional surgery and healthcare.

Right after his PhD, he worked towards the development of miniature sensors using photonic crystal fibres, aimed at providing force feedback for hand-held laparoscopic surgical instruments, such as laparoscopic staplers.

At University College London (UCL), he developed highly miniaturized single-element photoacoustic probes for detecting blood vessels in various needle-based interventions. He also led the development of a multimodal imaging probe for interventional cardiology, which combined both Optical Coherence Tomography (OCT) and Photoacoustic (PA) imaging.

Dr. Mathews was the sensor lead for a collaborative project with King’s College London on an ultrasonic needle tracking system for foetal surgery. He led the development of a sensorized needle integrated with fibre optic ultrasound sensors and the first clinical prototype of this tracking system.

At Echopoint Medical Ltd., he managed production runs for fibre optic pressure sensors, ensuring they met strict Quality Management System (QMS) guidelines.
