Pasupuleti Kedhareswara Sairam
I am Dr. Kedhareswara Sairam Pasupuleti, currently a Postdoctoral Researcher in the Department of Biomedical Engineering at Texas A&M University, USA. Prior I was worked at the Institute of Quantum Systems, Chungnam National University (CNU), South Korea, where I also ahve earned my Ph.D. in Physics. I holds my Master’s degree in Physics from Sri Venkateswara University, Tirupati, India. My research expertise spans the development of flexible and wearable sensor devices, electrochemical and acoustic gas sensors, nanomaterials synthesis (including 2D materials, polymer nanocomposites, and metal oxides), and thin film fabrication for applications in environmental monitoring, healthcare diagnostics, photodetectors, and energy storage. My current focus lies in the integration of bioelectronics and biosensing technologies with real-time electronics for health monitoring platforms.
