About

Khaldoon Ishmael is pioneering the intersection of wireless communications and biomedical sensing, with a focus on leveraging next-generation network infrastructure for non-invasive health monitoring. His key research areas include millimeter-wave (mmWave) communications, channel state information (CSI) analysis, and contactless physiological sensing. Ishmael’s major contributions demonstrate that standard wireless signals can be repurposed to detect subtle human motions—such as respiration—by analyzing how these movements modulate CSI in NextG systems. His 2022 paper on “Physiological Motion Sensing via Channel State Information in NextG Millimeter-Wave Communications Systems” (8 citations) lays the groundwork for using high-frequency bands to monitor vital signs without wearable devices. In a timely application, his 2021 work on “Identification of COVID-19 Type Respiratory Disorders Using Channel State Analysis of Wireless Communications Links” (5 citations) proposes a non-invasive, scalable method for early detection of respiratory infections, addressing critical gaps in pandemic response. By transforming everyday wireless links into health sensors, Ishmael’s research promises to make continuous health monitoring ubiquitous, reducing reliance on invasive tests and enabling proactive public health surveillance.
