one paragraph · read 30s

I build secure, low-latency systems where silicon meets physics — and data meets scientists.

I'm an Assistant Research Professor at the Institute for Applied AI Innovation (AAII) at The University of Texas at El Paso. My work centers on hardware security and cryptographic hardware on reconfigurable platforms — post-quantum KEMs, elliptic-curve and AES cores on FPGA — alongside signal/image processing and cloud-based AI/ML systems.

Before UTEP I was a Research Fellow at Florida Tech's Computational Mathematics & Data Science Center, building an AI-assisted, cloud-native repository for large-scale medical datasets on AWS S3 and Databricks. Earlier I spent two years at Lawrence Berkeley National Laboratory designing a GPU-accelerated Optical Frequency Domain Reflectometry platform with custom FPGA IP on the AMD Xilinx RFSoC 4x2 — <10 ms latency for distributed fiber-optic sensing. My Ph.D. at Concordia was on secure lossless image steganography, co-designed in hardware on Zynq-7000 SoCs.

Originally from Irbid, JO; grad school in Montréal, QC; currently in El Paso, TX. Off-hours: reading, gaming, building PCs, cooking, long drives, beach.
