Karen C. Cheung received the B.S. and Ph.D. degrees in Bioengineering from the University of California, Berkeley, USA, in 1998 and 2002, respectively. From 2002 to 2005, she was a Postdoctoral Researcher at the École Polytechnique Fédérale de Lausanne, Lausanne, Switzerland. She joined the University of British Columbia in 2006.
Dr. Yan Li’s research focuses on the microsystems with the integration of multiple components (i.e., electrical, electrochemical, fluid) for biomedical applications. In 2015, Yan joined in the university of British Columbia as a postdoctoral research fellow and is currently focusing on piezoelectric inkjet systems for cell printing, microfluidic graphene systems for biosensing as well as graphene neural interfaces. Yan received his B.S. degree from Xidian University (Xi’an, China) and M.Eng. degree from Peking University (Beijing, China); and the Ph.D. degree from IMEC & KU Leuven-University of Leuven (Leuven, Belgium) in 2015, where he developed a microfluidic system for energy harvesting and biosensing. Before UBC, he also worked in the retinal prosthesis project in Shenzhen Institutes of Advanced Technology, Chinese Academy of Science (Shenzhen, China).
Dr. Loic Laplatine’s research is focused on industrial technology transfer of biosensing techniques for medicine and environmental monitoring. His research interests include silicon photonics, optical microscopy, microfluidics and instrumentation. His current work is geared toward the proof-of-concept of an inexpensive disposable cartridge biochips that can be analyzed by a portable readout device to simultaneously measure the concentration of multiple analytes within tiny samples of physiological fluids or water. This project funded by a 2-year MITACS Accelerate grant is a collaboration between the Bio-Medical Micro Devices laboratory and the Photonics Research laboratory at UBC, and Luxmux, an industrial partner in Calgary. He also works on BioMEMS which reproduce the physiological hypoxic conditions (i.e. oxygen level) found in real tumors on 3D cell spheroids grown in vitro. He is mainly focusing on experiments based on two-photon and confocal microscopy to quantitatively analyze the spheroids response over time.
In 2014, he defended a Ph. D. in instrumental development for Surface Plasmon Resonance (SPR) microscopy at CEA Grenoble, France. His research led to a ten-fold improvement in image quality compared with previous commercial or research-based devices. This project was led in collaboration with Horiba Jobin Yvon and Prestodiag and targeted applications in the health and food safety industries. In 2010, he defended a MSc in physics engineering at INSA Toulouse, France. His main project was the development of a new immobilization method to image yeasts and Aspergillus spores by Atomic Force Microscopy (AFM) at LAAS-CNRS, Toulouse, France. He also worked on a novel label-free biosensing technique based on the diffraction of Moleculary Imprinted Polymer (MIP) in collaboration with Innopsys.
Samantha is passionate about learning, solving problems, and working on interdisciplinary research. Her research focuses on using microfluidics to recreate the microenvironment of cells within tumours during in vitro experiments such as drug screening. Specifically, she uses 3-D cell culture and on-chip oxygen control to recreate chronic and time-varying low oxygen levels that can exist in tumours and influence cell behaviour and drug response. Samantha has also integrated optical oxygen sensors, measured using fluorescence microscopy, into these environments as well as worked on novel imaging protocols to improve data analysis from 3-D cell cultures. In addition to her thesis work, Samantha has designed and tested optical biosensors using silicon nanophotonics technology combined with microfluidics. Samantha has completed her PhD work and will receive her degree in November 2016.
Jonas is defending his PhD thesis, entitled “Enhancing the Performance of Silicon Photonic Biosensors”, in September 2016. He is a Product Marketing Manager at Lumerical Solutions, Inc.

Research topic and description: Monitoring Water Quality Using Silicon Photonics Sensors and Technologies.
The presence of pesticides in water monitoring is important for applications in drinking water and for monitoring agricultural run-off. This project investigates the design of a SOI chip with waveguides featuring strong fluid interaction to detect the effective index change caused by pesticide molecule on the silicon photonic sensor.
Research interests: Bio-Sensors, Optical Sensors, Microfluidics
