PostDoc Opportunity in 5G/NextG Positioning

I am looking to hire a motivated postdoctoral fellow to conduct high-quality experimental wireless research in NextG Wireless Lab at George Mason University, starting August 2022 (or earlier). The successful candidate will contribute to the recently NIST-funded project on 5G-based Indoor Positioning System and will also have the opportunity to collaborate with other teammates at NextG Wireless Lab@Mason, and our academic and industry partners on the exciting topics of 5G/NextG communications, Open AI Cellular (OAIC), and spectrum sharing.

Project Description

This project proposes to design, prototype and demonstrate a highly precise 5G-based Indoor Positioning System (5G-IPS) that addresses three long-standing and difficult challenges in emergency environments (i) global navigation satellite system (GNSS) and traditional global positioning system (GPS) do not work reliably in indoor setting, (ii) reliable communication infrastructure may not always be available, and (ii) accurate mapping and visualization of the building map may not be available. UAVs mounted with 5G base stations or user equipment [UEs]) will be utilized for enabling cellular-based (viz. 5G NR) positioning along with specific enhancements to precisely localize firefighters within a building. Then, a key 5G capability, called network slicing, will be utilized to securely, reliably, and timely disseminate the time-critical position information (and other important audio/video or sensor information) from firefighters to the safety stakeholders that need to know it. Following this, a mapping and visualization tool will be prototyped to accurately track the position of firefighers within the visual 3D map of the building. The 5G-IPS system will be demonstrated in-lab using NextG Wireless Lab@Mason’s 5G O-RAN testbed, followed by in-field building test setting in collaboration with Arlington County Fire Department.

Required Qualifications

  • PhD degree in Electrical Engineering, Computer Engineering, Computer Science, Telecommunications or related areas.
  • Excellent knowledge of 5G/NextG wireless. Knowledge of machine learning will be a plus.
  • Hands-on experience with at least one of the SDR platforms and FPGA programming.
  • Very good publication record in top academic conferences and journals
  • Excellent team player and good communication skills while being able to work independently.

Your application must include:

  • A research statement (max. 2 pages) indicating your research interests, achievements, plans and how these fit with the above position requirements and our ongoing research
  • Curriculum vitae including the list of publications, R&D skills, awards, fellowships, grants etc.
  • Names of at least two references

How to Apply?

Send the required documents as a single pdf file directly to vshah22@gmu.edu, with Subject="Postdoc-application-FirstName-LastName".

Two PhD Positions Available

I am looking for two self-motivated students to join my group, starting Fall 2022 or Spring 2023. The selected candidate will be involved in carrying out experimental research and prototyping of next-generation wireless communications and networking, using in-lab 5G/NextG wireless testbed at Mason.

Required Qualifications

  • Hold a M.S. (or B.S.) degree in ECE, CS, IT, Cybersecurity, or other related disciplines.
  • Strong programming skills (e.g., Python, Matlab etc.)
  • Solid background in mathematics and analytical thinking

  • Ability to work in an inter-disciplinary team

Preferred Qualifications

  • Strong background in wireless communications and networking, particularly, 5G and next-G technologies
