Koko K.H. Lam is currently an Associate Professor and Associate Head of Department. He received the M.Phil. and Ph.D. degrees in Applied Physics from The Hong Kong Polytechnic University (HKPolyU). During his graduate studies, he worked on the processing and characterizations of piezoelectric materials and their applications in sensors and actuators under the supervision of Prof. Helen L.W. Chan. He was a visiting scholar in Stanford University in 2007. From 2007 to 2009, he acquired the HKPolyU-funded Postdoctoral Research Fellowship and worked on the applications of smart materials in civil engineering structures at HKPolyU. Meanwhile, he also joined an international project (collaborated with Stanford University, University of Michigan, and Georgia Institute of Technology) to conduct wireless vibration monitoring of Guangzhou Television and Sightseeing Tower in China. He joined the group of  Prof. Kirk K. Shung as a Research Associate at the NIH Resource Center on Medical Ultrasonic Transducer Technology in the Department of Biomedical Engineering of University of Southern California (USC) from 2011 to 2013. He started his academic career as an Assistant Professor in Department of Electrical Engineering at HKPolyU in 2013.


Dr. Lam has been working in the field of smart materials and applications including materials for energy conversion (e.g., piezoelectrics, thermoelectrics, multiferroics, photocatalysis, etc.) and storage (e.g., electrode materials for rechargeable batteries, dielectrics, etc.), ultrasound transducer technology, biomedical and non-destructive applications of ultrasonic transducers, smart sensor and actuator technology, and condition and structural health monitoring. He has achieved 180+ publications, including 7 patents for 6 inventions, 155+ SCI journal papers, and 15+ international conference papers.


Dr. Lam received an Early Career Award in 2014 presented by Research Grants Council of Hong Kong. He has been a Visiting Professor in South China Normal University since 2015. He is an Exco member of Ultrasound Transducers and Materials Society, China Association of Medical Equipment - Medical Ultrasound Equipment Society, a Secretary of IEEE Hong Kong Joint Chapter of PES/IAS/PELS/IES (IEEE JC PIPI), a Senior Member of the IEEE Society, and a Member of American Chemical Society. He has also served as a Member of local/overseas examination boards, an Organizing Committee Member of international conferences & seminars, and a Reviewer for over 50 prestigious international SCI journals.
