Graduate device research, undergraduate quantum optics, and independent projects
Built coupled electrothermal TCAD models of AlGaN/GaN HEMTs to characterize self-heating, junction temperature behavior, and DC/RF performance trade-offs across bias conditions. Calibrated material parameters, mesh strategy, and contact models against published device data.
Wide bandgap device physics, electrothermal modeling, self-heating behavior, and the connection between device-level findings and process integration, reliability, and yield. Includes work on vertical GaN power devices in the lab.
Worked with memristive devices in the lab, including device characterization and basic crossbar array configurations.
Applied model-comparison study for EUV/DUV lithography. Benchmarks aerial-image energy deposition predicted by a Double-Gaussian PSF (FFT convolution) against a Monte Carlo particle model. Includes partial-coherence modeling, flare analysis, and swing curves.
25 to 50 Gbps silicon photonics transceiver simulation framework using Lumerical-style modeling. Compact model development, link budget analysis, and process variation sensitivity.
Complete 28 GHz millimeter-wave frontend design covering GaN power amplifier, low-noise amplifier, 8×8 phased-array beamforming, digital predistortion, and adaptive impedance matching. S-parameter analysis, load-pull, and thermal management tied back to the GaN HEMT TCAD work above.
RF power amplifier design for 5G/6G mmWave using GaN HEMT devices (0.15 μm process) in a 2:1 asymmetric Doherty architecture, linearized with memory-polynomial digital predistortion. Design targets: 43 dBm P1dB, 65% peak PAE, 400 MHz instantaneous bandwidth, ACPR −48 dBc with DPD enabled, EVM 1.8% on 256-QAM.
Bridge between the AlGaN/GaN HEMT TCAD work and system-level RF design. Self-heating shifts I–V curves, moves fT/fmax, and degrades linearity at high drive levels — setting the scope for how thermal management feeds back into PA architecture choice and DPD coefficient drift.
Experimental and theoretical research on Electromagnetically Induced Transparency (EIT) in atomic systems for slow light demonstrations. Conducted as undergraduate research at UConn.
Undergraduate research on quantum memory demonstrations using EIT-based protocols in atomic systems.
Monte Carlo simulation across two contexts: photon transport modeling for the DUV energy deposition project, and molecular beam simulations from undergraduate research.
