Research Summary:
I have applied electrical engineering methods to solve problems in the areas of mobile and wearable sensors for activity, health, environment and wellness monitoring. My research has involved narrowing the gaps between larger clinical grade devices and various newly developed mobile and wearable health sensors in terms of the hardware, algorithms and signal processing techniques used by the two different areas. In particular, my research has focused on the development of wearable biosensors, bio-circuit systems and therapeutic devices for use in diagnostics and monitoring of chronic diseases such as hypertension, diabetes, obesity, and sleep disorder. To achieve these objectives, I use RF and analog/mixed signal circuit design knowledge for solving problems related to measuring, acquiring and processing an individual’s physiological signals. I believe ultra-low power yet high performance RF and analog circuit design technology helps us understand mechanisms of disease development and treatment.
