Electrical Engineer
I am currently employed as an electrical engineer at Mobilion Systems Inc. Mobilion Systems develops an Ion Mobility product to be paired with an Agilent Q-Tof mass spectrometer to provide an additional dimension to mass spectrometry data analysis.
In my role as electrical engineer, I was responsible for electrical subsystem design for product development and proof of concept prototyping. This involves taking a design though our product development lifecycle, starting with the identification and acceptance of functional requirements, all the way through design release to our internal manufacturing team. As a part of the product development lifecycle, I was also responsible for the verification and qualification testing of subsystems and proof of concept prototypes, as well as designing and building any required infrastructure to carry out this verification testing. I also work closely with out internal Research and Development and Manufacturing team to provide support for their projects and ensure the accurate transfer of information between functional groups.
At Mobilion, I use a variety of engineering and project management tools as a part of my day-to-day responsibilities. I regularly use LTSpice for circuit analysis and solution conceptualization. I am well versed in utilization of STM32 based microcontrollers along with STM32CubeIDE to write firmware for design and verification testing. I am proficient in Altium Designer for schematic and PCB design, component library management, BOM management, and technical drafting using Altium’s Draftsman tool. I also am proficient in Jira and Confluence for issue/task tracking and documentation respectively.
Due to the sensitive nature of this position, I am unable to publish any design work I have completed in this role publicly. However, I would be happy to discuss my experience in greater detail in a confidential setting.
Engineering Technical Consultant
I worked under Robert Cargill III, P.E. for two years as a technical and engineering consultant at CBE Consultants. During my tenure, I assisted with the analyses of injury causations and accident reconstructions for a variety of projects. Some of my responsibilities involved assessing whether motions, accelerations, and loads can cause injury. I also contributed to analyses and reconstructions of motor vehicle crashes, sports and occupational injuries, and falls.
As a consultant, I also contributed to biomechanical analyses of incidents involving consumer devices. Some projects I lead focused on rolling knee walkers, hydraulic lifts, and amusement devices (e.g. roller-coasters and water rides). These evaluations would include the analysis of biomechanical issues and injury potential associated with alternate scenarios, such as changes in design or safety equipment.
At CBE Consultants I designed mathematical models of real systems, made 2-D and 3-D modeling of scenarios, evaluated and examined exemplar products, wrote scripts using the python library to rapidly iterate different potential solutions, and created and ran studies with human surrogates to recreate scenario conditions.
Due to the sensitive nature of my previous work, I am unable to publish all of my work products publicly. However, I would be happy to discuss my experience in greater detail in a confidential setting.
Revit Technician
My primary duty at HBS Inc. was designing Revit Families for our Hospital Equipment Planning department. Over the course of my employment, I created over 50 parametric families for placement in linked Revit projects. These families ranged from paper towel dispensers to entire operating suites. I also collaborated with clients and contractors to coordinate the equipment needs for new and existing hospitals. One project of note was a $200 million expansion to Penn State Medical in Hershey, PA.
Neural Stimulator
Animal locomotion and response to stimuli are common research topics for academic study. In my graduate thesis lab, we regularly conducted experiments into the h-reflex response of laboratory mice—a tedious and time consuming process. To elicit the proper responses, a technician would have to manually adjust the amplitude of an expensive power supply and then record the resulting waveforms. I knew there had to be a more efficient and cost effective way to run these experiments, but none seemed to exist. So, I decided to take matters into my own hands and focus my graduate thesis on improving the process.
The resulting solution was a low-cost and programmable constant neural stimulator. This device used developments in Op-Amp technology to allow for the inexpensive construction of a current source. It could be easily controlled with a consumer-grade microcontroller (Teensy 3.0) and be programmed by a technician to send a sweep of triggers. This automated the process of changing the source amplitude and recording of the resulting waveform.
Feedback Controlled Treadmill
As a member of my undergraduate locomotion laboratory, I would often test various animals’ responses to stimuli while they were in motion. To do this, I used our lab treadmill that could be programmed to speed up, slow down, and perturb the treadmill belt to elicit a pitching or rolling moment in the subject.
For my senior design project, I modified the functionality of the treadmill and added modules to assess the yaw-response of a cockroach. The module would track the position and speed of a target. After the target was in the middle of the running treadmill for a user-defined amount of time, a servo would activate. This would actuate the walls until the target left the moving area of the treadmill. The target would then step onto the stationary portion of the treadmill, causing it to yaw.
Personal Projects
Engineering is something I enjoy doing both in and out of the office. This recent passion project was inspired by my love for circuitry and disdain for a certain battle royal game.
I programmed my Plummet Pal to play an audio file whenever the accelerometer inside detects a certain threshold of motion (in this case, a fall).
Take a look.
