Student Advisory Committee

The Department of Electrical and Computer Engineering (ECpE) Student Advisory Committee (SAC) at Iowa State University is a group of electrical, computer, software, and cyber security engineering students currently enrolled in an undergraduate EE, CprE, Cyb E, or SE program of study at Iowa State who are interested in the vitality of the ECpE department. The committee acts as a consultant to the ECpE department chair to strengthen the department’s undergraduate academic and outreach programs; improve its facilities usage as it pertains to undergraduate teaching and research; and expand its available support to current students and future alumni. SAC members actively participate in the continual assessment of the department’s progress and the development of policies and activities as they pertain to the undergraduate experience in the department.

SAC members actively assist in recruiting new members, as well. The committee serves at the discretion of the ECpE department chair.

Json Rangel  Json Rangel 

Json Rangel is a senior in electrical engineering with an emphasis on communication systems and a background in music technology. He is from Rock Island, IL, and currently serves as the President of the Iowa State University Branch of the Institute of Electrical and Electronics Engineers (IEEE). Json chose to pursue electrical engineering due to his curiosity at youth on circuits and the uses of electricity, and his overall fascination with wanting to know how things worked. He ventured into communication systems after classes in signal processing and music technology and wanted to continue learning about the uses for signals in communication systems, such as radios, telecommunications, and networking. Outside of class, he enjoys watching sports, supporting Cyclone athletics, listening to and creating music, and spending quality time with family and friends.
