My research interests span the medical informatics, and clinical/health informatics requiring interdisciplinary collaborations with experts such as cardiothoracic surgeon, neuropsychologists, roboticist, psychologist, physical therapist, dietician, nurse and occupational therapist. Given my engineering background and interest in medicine, my research has evolved into various segments of biomedical informatics such as personalized medicine, sensor based assistive mobile technology, and robotic assistive technology. Sensor based assistive mobile technology In the area of sensor based assistive mobile technology my projects utilize sensors for tracking heart rate, blood pressure, body surface temperature, oxygen saturation, accelerometer, and pressure sensors to monitor and track various physiological conditions that play a role in prevention of pressure ulcers, tracking, monitoring and management of bipolar disorder, and detection of wandering in patients affected with dementia. In collaboration with Dr. Adriana Seelye, a neuropsychologist from the Department of Veterans Affairs, I am exploring the use of wireless sensors in predicting behavioral and psychological symptoms of dementia (BPSD). Most studies conducted in this area are reactive in identifying the BPSD while we are exploring a proactive approach of prediction. We are combining reminiscence therapy and wireless sensors along with mobile technology to help predict the onset of a BPSD episode. In an extension of this project I am also exploring the use of a combination of physiological and geolocation sensors in predicting wandering in individuals affected with Alzheimer’s Disease (AD). Continuing my research on Alzheimer’s, we are attempting to aid recall of deeply embedded memory, by building upon the research conducted by Neurologist, Dr. Oliver Sacks, where music is used to recover deeply embedded memories. A mobile application was developed by combining cues such as photos, music and videos from an event of significance importance to the affected individual, into a multimedia presentation to help jog deeply embedded memories related to this event. Robotic assistive technology More recently I have been working in the area of robotic assistive technology in helping patients recover after open heart surgery and help maintain quality of life in individuals affected with Alzheimer’s disease. I am currently collaborating with a cardiothoracic surgeon from the St. Lukes Hospital in developing a robot assistive technology to help patients recover after open heart surgery. We are using Baxter the humanoid robot in exploring impedance control to help a patient out of bed. I have secured the Whiteside grant ($20,533) to conduct a proof of concept study to explore the use of robotics in helping individuals recover after open heart surgery.
