Layout of Printed and Flexible Circuit Boards for use in vacuum and cryogenic environments with Altium Designer and SOLIDWORKS

Design and specification of cabling, connectors, and feedthroughs for the High resolution Infrared Spectrograph for Exoplanet Characterization (HISPEC) cryostat, including video and clock signals of the Teledyne Hawaii-4RG CMOS detector and 100+ four-wire temperature sensors; interface with mechanical engineers and project managers to ensure proper integration

Fabrication of custom wire harnesses for the Next Generation Palomar Spectrograph (NGPS)

Hand soldering of fine-pitch surface mount components on custom PCBs

Developed custom firmware and data visualization tools for the COO laser profilometer; ran scans of science grade CCD detectors for the DEIMOS Throughput Upgrade project to characterize focal plane alignment

Created and tested the first prototype of a 500MHz dipole antenna array for radio astronomy and Fast Radio Burst (FRB) detection

Simulated and optimized antenna performance with Ansys HFSS software

Designed and fabricated a low-noise amplifier (LNA) circuit board using KiCad and Keysight Advanced Design System (ADS)

3D modeled and printed mechanical supports for the antennas using OnShape

For my Senior Thesis, collaborated with RF engineer colleagues to scale up the design for a 256-element array to be deployed at Owens Valley Radio Observatory

Prototyping and testing of LoRa-based radio communications for (short term) high-altitude balloon payloads and (long term) an orbital CubeSat

Restoring Moore Lab's 6m radio antenna for astronomy and satcom applications (Receiver calibration, signal pathway component selection, RFI hunting)

Mentor junior members (mechanical, electrical, comp sci principles)

Analyzed "waterfall" data of Fast Radio Bursts (FRBs) from the CHIME/FRB Public Database utilizing unsupervised machine learning tools (UMAP, t-SNE, k-means)

Created interactive plots to visualize how the algorithms categorized individual FRBs

Arrived at evidence for a single astrophysical origin of FRBs

Integration and testing for flight models of AERO/VISTA CubeSats

Developed an open-source ground station interface with GNU Radio to automate satcom operations for Westford Radio Antenna UHF uplink/downlink

Prototyping and manufacturing design for electric vehicle battery packs

Used CATIA/3DEXPERIENCE software to design parts/assemblies

Ran environmental tests (vibration and ingress) on high voltage & structural battery components for integration into vehicles

Led hardware team and collaborated with software engineers; organized and integrated efforts to develop a suite of novel, low-cost, and patentable remote water sensors

Identified and resolved water analysis needs of industrial customers for process improvement and cost savings, e.g. in-situ water chemistry measurement, real-time data analytics, etc.

Designed plug-and-play sensor frameworks using 3-D CAD and simulation programs

Fabricated, tested, and deployed sensing solutions; ran on-site beta tests with customers
