I validate and characterize hardware at the bench — from PVT corner sweeps and signal integrity analysis to bare-metal firmware on STM32 with statistical methodology and oscilloscope-driven debug. Currently seeking co-op or full-time roles in hardware validation, platform validation, or characterization engineering.
I'm Athish — M.S. Electrical Engineering at Case Western Reserve University. I validate and characterize hardware using oscilloscopes, DMMs, logic analyzers, and bare-metal firmware written at the register level. My work follows semiconductor-industry PVT methodology — every measurement includes sample count, mean, and standard deviation.
Right now I'm running a full platform validation campaign on an STM32F446RE — characterizing GPIO timing determinism, power rail integrity, and communication bus signal quality across voltage corners from 2.8V to 3.6V. I've also built a 5-stage pipelined RISC-V CPU with a custom systolic array coprocessor, hardware-validated on Zynq UltraScale+ at 138 MHz with 36/36 tests passing. Before grad school, I was debugging live transducer signals in a petroleum plant at ONGC — oscilloscope on noisy lines, root-causing grounding faults, calibrating field instruments. That hands-on instinct carries into every bench session.
Looking for a Fall 2026 co-op or full-time role in hardware validation, platform validation, characterization engineering, or system-level test.

Every project below is verified, synthesized, or deployed. The results are real.
A complete SoC — 5-stage pipelined RISC-V processor with the full RV32IM instruction set, zero-penalty data forwarding, load-use stall detection, branch flush, and a custom md_result_captured latch that solves a tricky M-extension pipeline timing hazard.
Register-level I2C driver for BME280, register-level SPI driver for ADXL345 accelerometer, CAN 2.0B transmission via SN65HVD230. FreeRTOS managing four concurrent tasks through queues and mutexes. Python host-side visualization via UART. No HAL, no Arduino — datasheets and peripheral registers.
An event-driven surveillance system running on a Raspberry Pi. A 4-state finite state machine classifies motion into four activity levels using frame-differencing and adaptive thresholds, then automatically adjusts the recording mode.
A research project exploring hafnium-oxide-based ferroelectric architectures — FeRAM, FeFET, and NCFET — for next-generation non-volatile memory and steep-slope logic applications. Covers material physics, phase transitions, polarization mechanisms, and CMOS fabrication compatibility.
Designed a streaming datapath computing y = (a×b) + (c×d) + e on signed 16-bit fixed-point inputs with a valid-ready handshake interface. Built both an unpipelined single-cycle version and a parameterized pipelined version with configurable depth (2–5 stages).
Three compute modes — sequential MAC, 4-way parallel MAC with an adder tree, and early-exit with a magnitude comparator. Controlled by a 5-state hybrid Moore/Mealy FSM with stall handling, output backpressure, and built-in hardware performance counters.
Modeled a one-dimensional abrupt p-n junction using COMSOL Multiphysics. Simulated electrostatic potential, electron/hole concentration profiles, net charge density, and electric field under equilibrium, forward bias (0 to +0.5 V), and reverse bias (0 to −1.5 V). Parametric sweep over donor concentration Nₐ ∈ {1, 2, 5} × 10¹⁶ cm⁻³.
Extended the 1D model to a full 2D p-i-n junction (12×6 µm) solved via coupled drift-diffusion PDEs in COMSOL. Studied photodetector and solar-cell behavior by sweeping optical generation rate G₀ under zero and −2 V reverse bias. Derived the logarithmic scaling of quasi-Fermi level splitting: ΔEf ≈ 2Vt · ln(G₀τ / nᵢ).
A hand-soldered analog signal conditioning circuit — op-amp gain stage plus LDR voltage divider — interfaced to an 8051 microcontroller via ADC. Built for fluid-level detection in medical IV bottles.
A remote monitoring system that publishes sensor data over MQTT with TLS encryption to AWS IoT. Supports actuator control through cloud-triggered GPIO callbacks and I²C sensor interfacing.
A Wi-Fi-enabled notice board that receives messages through a web interface and displays them on an LCD screen in real time. Uses ThingSpeak for cloud-based logging.
A closed-loop fan speed controller built with an Arduino and an LM35 temperature sensor. PWM-regulated. Hand-soldered on a breadboard.
The tools, languages, and platforms I use to design, simulate, build, and debug.

I'm actively looking for Fall 2026 co-op or full-time opportunities in hardware validation, platform validation, characterization engineering, or system-level test. Based in Cleveland, OH — happy to chat about any role that involves bench work, oscilloscopes, and quantitative hardware characterization.
