Seattle, Wa

- Spearheading effort for train control's standard specifications and directive drawings update, which involves a rewrite and update of our Specifications as well as an additional 23 new drawings added to our Directive Drawings- Resolving train-to-wayside communication (TWC) issues with bidirectional communication between train and wayside loops and auto-tuning feature of these loops resulting from EMI from light-rail vehicles- PTC support for Lakewood Subdivision, a sub operated by BNSF but owned by Sound Transit with maintenance contracted to local electrical contractor- Creating documents and whitepapers as needed for informing or motivating

Boston, Ma

- Completed capital projects such as the Maverick crossover activation, new vehicle testing for the Red Line, Green Line state-of-good-repair Microlok II replacement as well as maintenance projects like rewriting a LabVIEW program to perform track mapping for monitoring and recording track frequencies on the Red and Orange lines- Verified and checked control line logic for iVPI upgrades- Troubleshot service calls like signals not clearing, trip stops not going down, and OCC calls not going out to field- Set NTP time clock as source for the Green Line extension and helped as well as documented Comms getting Normal & Standby fibers to the right locations for new GLX- Participated in testing from Factory to Field Acceptance, Site Acceptance, and System Integration tests for the entire GLX and parts of Red Line/Orange Line Signals Upgrade

Boston, Ma

- Supported other departments with prospects, project management, and new technology R&D- Managed large-scale implementation of speaker and PA systems for customers across the world with projects as large as $750k- Tested speaker drivers and acoustic properties for ATI's flagship product, a 1600W giant voice tower- Closed sales with salespeople and maintained relationships with existing customers for their satisfaction- Tested software functionality and created requirements for development team for new projects- Helped with ISO processes and created documentation and spec sheets for products

Anaheim, California

Two-year post baccalaureate Bible truths and church service training focusing on leadership, service, community involvement and campus mentorship, and Biblical truths- worked on Django APIs in Python- automation testing using Selenium-Python- coded and troubleshot JS, CSS, and Django bugs

Omaha, Ne

- Implementation and installation of AEI tags in the rail that slow down remote control locomotives (RCL) in certain remote-controlled zones of a yard- Project management of a safety critical system that improves the efficiency of switching cars by eliminating redundancy, preventing proneness to human error, and improving procedures- Work with vendors, contractors, and operating and supply departments to secure budget, request work gangs and crews, order parts, and test new remote control operation in yards- Use MicroStation (CAD) to create final version documents detailing the installation of RCL pucks in Kansas City, Salt Lake City, Oakland, Lake Charles, and locations throughout UP's network

Omaha, Ne

- Tested Positive Train Control (PTC) via Field Quality Tests (FQTs) on locomotives and mobile laboratory boxcar in the LA basin, ensuring valid communication on 220 MHz and evaluating vendor software for safe and efficient operation of a locomotive given trip-specific parameters- Monitored 10,000 wayside messaging servers (WMS) on the air via Spacewalk, checking for health and statuses of systems (clients) connecting to multiple servers, and fixed broken WMSs remotely or via technicians- Verified Linux-based radio communication system for Class I railroads provided by a third-party vendor- Wrote Python scripts to generate plots for radio performance analysis and performing statistical evaluations on radio performances using cumulative distribution functions and normal Gaussian parameters

Omaha, Ne

- Developed an Event Recorder Simulator for locomotive signals such as speed, throttle, cab signals, tractive effort, horn, brake pipe pressure, and EOT radio using LabVIEW.- Synchronized several tasks by using counters for digital, analog, and electropneumatic outputs in the compact DAQ chassis.- Developed bill of materials (BOM) software to push new firmware to radios using an auxiliary card cage located on locomotives; tested process for updating software on locomotives and wayside servers

- Conducted genetic research on the Y chromosome of Drosophila melanogaster- Performed pigment assays to determine effect of several gene mutations on Y-linked position effect variegation (PEV)- Published results as a second-author on genetic makeup of the heterochromatic Y chromosome and the pathways that monitor gene expression on the Y chromosome in a PLOS One paper- Verified mutations through specific experiments including primer design, PCR, qPCR, mitotic squashing, DNA sequencing, and gel electrophoresis

State College, Pennsylvania Area

- Configured a custom-made near-field scanning optical microscope (NSOM)- Systematically debugged and worked through system to determine root cause of failure- Determined the resonance frequency for the optical fiber attached to the tuning fork in order to use feedback control to operate the optical fiber tip- Achieved near-field nanometer resolution by raster-scanning the sample of interest using a piezoelectric motor- Used LabVIEW code to watch system and to monitor the output and input signals of the optical system

- Researched novel enzyme isonitrile hydratase and calculated kinetic constants such as Km and Vmax using fluorescence spectrophotometry.- Learned crystallography, protein purification, plasmid transformation, among many wet lab techniques- Published paper in Journal of Biological Chemistry
