Opportunities

The Intelligent Radio and Integrated Systems (IRIS) Laboratory is actively recruiting motivated students and researchers to join the group. We offer a research environment that combines theoretical analysis, hardware development, and experimental validation using state-of-the-art design tools and measurement equipment.

Open Postgraduate Positions

• Postgraduate Student (Digital Signal Processing) Developing signal processing schemes and analytical models to counteract hardware limitations in high-frequency RF communication systems. Core topics include array calibration, transmitter linearization, and advanced test and measurement techniques for next-generation terrestrial and non-terrestrial communications. Preferred background: signals and systems, communications, applied mathematics, or closely related fields.

• Postgraduate Student (Antenna Design and System Integration) Designing antennas and arrays, RF passive circuits, and system-level integration for next-generation wireless systems, with emphasis on sub-10 GHz MIMO transmitters and millimeter-wave SATCOM beamforming arrays. Preferred background: electromagnetics, antenna theory, RF/microwave engineering, or related fields.

• Postgraduate Student (RF Active Circuit Design) Designing high-efficiency and ultra-wideband power amplifiers, frequency multipliers, and analog predistortion circuits for next-generation wireless and SATCOM systems. Preferred background: analog and RF circuit design, electronics, RF/microwave engineering, or related fields.

Undergraduate Research

The IRIS Laboratory welcomes undergraduate students interested in gaining research experience through the Undergraduate Research Opportunities Program (UROP) or research internships.

UROP students work closely with the PI and postgraduate researchers on projects related to RF circuits, antenna arrays, signal processing, and measurement techniques. These positions are well suited for students considering graduate studies or seeking hands-on research experience. Applicants from diverse backgrounds — including ECE, CPEG, CS, and MECH — are encouraged to apply.

How to Apply

HKUST values diversity and welcomes applications from all qualified individuals.

Interested candidates should email a complete application package to Prof. Ahmed Ben Ayed, consisting of the following:

• A cover letter stating your research interests and experience, and how they relate to one of the positions described above.
• A curriculum vitae, including the names and contact information of two or three academic or professional references.
• An electronic copy of your most significant research output (thesis, journal paper, or conference publication), if available.

Please attach all documents in PDF format and include the position title (e.g., “PG Application — Digital Signal Processing”) in the subject line of your email.

Undergraduate applicants may instead send a short statement of interest and a summary of their academic background.

We will respond to eligible candidates within a reasonable time frame. All positions remain open until filled.
