Most of the long-term health problems associated with diabetes, such as nephropathy, retinopathy, neuropathy, cardiovascular diseases and cerebral vascular events, result from the sustained hyperglycemia (blood glucose > 11 mmol/L). Statistics Canada data shows that in 2005, 4.3% of adults was diagnosed with diabetes mellitus. This increased to 6.8% in 2008/09. According to the Public Health Agency, there are an estimated 60,000 new cases of diagnosed diabetes every year in Canada. Frequent glucose monitoring and tight glucose control have been shown to improved patient health, better quality of life, and tremendous healthcare savings. My research has taken two directions towards a common goal. The first direction of my research is specifically targeted towards the development of a physiological model suitable for simulation, performance assessment, and evaluation of diabetic managements for clinical purposes. The second direction is related to the measurement of blood glucose. Any frequent glucose monitoring requires the use of a reliable non-invasive glucose sensor. Different approaches have been used to develop such a sensor which is considered the "holy grail" in diabetic monitoring and control. Most common approaches include light-based and enzyme-based measurements of body fluids such as sweat and blood. My on-going work has been focusing on the light-based approach. We also developed the first multi-organ compartment diabetic model for type II diabetes mellitus and pioneered the first device to demonstrate the proof of concept to measure accurately glucose level in solution and serum. The long-term objectives of my research are 1) to improve the management of blood glucose by employing a clinically-relevant physiological model and fault detection features suitable for monitoring and control, and 2) to improve the accuracy of optical glucose sensors. For the next five years, four specific projects have been identified to guide this research program into reaching its long-term objectives: 1) Develop a fault detection and isolation scheme for the insulin-glucose system using advanced statistical methods. 2) Evaluate the pharmacological impact of different treatment approaches. 3) Develop multi-laser-based micro-sensor based on absorption/reflectance spectroscopy 4) Development of evanescent field sensors for glucose measurements. The ultimate goal of my research is to benefit our society by advancing engineering research into bioprocesses particularly in managing diabetes mellitus, which is one of the most prevalent diseases affecting Canadians today.

与糖尿病相关的大多数长期健康问题，如肾病、视网膜病变、神经病变、心血管疾病和脑血管事件，都是由持续的高血糖症（血糖> 11 mmol/L）引起的。加拿大统计局的数据显示，2005年，4.3%的成年人被诊断患有糖尿病。2008/09年，这一比例上升到6.8%。根据公共卫生署的数据，加拿大每年估计有60，000例新诊断的糖尿病病例。频繁的血糖监测和严格的血糖控制已被证明可以改善患者的健康状况，提高生活质量，并节省大量的医疗费用。我的研究朝着一个共同的目标采取了两个方向。我的研究的第一个方向是专门针对适合模拟，性能评估和临床目的的糖尿病管理评估的生理模型的开发。第二个方向与血糖测量有关。任何频繁的血糖监测都需要使用可靠的非侵入式血糖传感器。已经使用不同的方法来开发这样的传感器，其被认为是糖尿病监测和控制中的“圣杯”。最常见的方法包括基于光和基于酶的体液测量，如汗液和血液。我正在进行的工作一直专注于基于光的方法。我们还开发了第一个用于II型糖尿病的多器官隔室糖尿病模型，并开创了第一个设备，以证明准确测量溶液和血清中葡萄糖水平的概念验证。我的研究的长期目标是：1）通过采用临床相关的生理模型和适用于监测和控制的故障检测功能来改善血糖管理; 2）提高光学葡萄糖传感器的准确性。在未来五年，已经确定了四个具体项目，以指导该研究计划实现其长期目标： 1)使用先进的统计方法为胰岛素-葡萄糖系统开发故障检测和隔离方案。 2)评估不同治疗方法的药理学影响。 3)基于吸收/反射光谱的多激光微传感器的研制 4)用于葡萄糖量测之渐逝场感测器之发展。 我的研究的最终目标是通过推进生物过程的工程研究，特别是在管理糖尿病，这是当今影响加拿大人的最流行的疾病之一，使我们的社会受益。
