Hi! I'm a first second-year PhD Student at Northwestern University, advised by Prof. Fabián E. Bustamante.
My research interests are broadly in network measurement, analysis, and engineering.
I enjoy studying how infrastructural and geolocational characteristics of network systems impact measurements, with the goal of leveraging these insights to develop performance enhancing solutions.
My recent research topics include cellular roaming and global connectivity, Bluetooth Low Energy (BLE) tracking, and satellite networks.
Previously, I was a research assistant at Communication Networks Lab in New York University Abu Dhabi, where I was advised by Prof. Yasir Zaki. I am also a recipient of the Tamayyuz (Excellence) Research Fellowship.
I watch professional baseball in my free time, although the lifelong experience of being a Hanwha Eagles fan has rarely proven stress-relieving.
