PhD Candidate in Electrical Engineering at McGill University

I design decoding algorithms and the hardware that runs them, so that 5G and 6G links can be both reliable and fast.

Open to industry and academic positions starting in 2027

I am a PhD candidate in Electrical Engineering at McGill University, where I work in the Integrated Systems for Information Processing (ISIP) Lab under the supervision of Prof. Warren J. Gross. My research is on modern error-correcting codes for 5G and 6G communication systems.

My work spans guessing random additive noise decoding (GRAND), ordered statistics decoding, polar codes, optimization-based decoders, and machine learning decoders, with an emphasis on algorithms that map well to efficient hardware. I co-authored the Springer book Guessing Random Additive Noise Decoding: A Hardware Perspective, and I have been a teaching assistant for computer organization and digital systems courses at McGill since 2020.

I am looking for industry or academic positions starting in 2027 in channel coding, digital communications, decoder hardware, and machine learning for communications.

Research

Universal decoding (GRAND & OSD)

Code-agnostic decoders that guess the noise rather than the codeword, including GRAND variants and partial ordered statistics decoding with better error patterns.

Polar codes & HARQ

Successive-cancellation and list decoders for polar codes, and making incremental-redundancy HARQ practical for them.

Decoder hardware (VLSI)

High-throughput, energy-efficient decoder architectures, from algorithm–hardware co-design to ASIC and FPGA results.

Optimization-based decoding

Casting decoding as an optimization problem, using QUBO formulations and simulated annealing.
