Design & Build
96 Channel Pipette Matrix Spacer
for University of Minnesota Genomics Lab, 2021 Transferring samples from vials in a rack into a well plate is a tedious process for users at the University of Minnesota's Genomics Lab. On a team to automate the entire process, I worked on the channel matrix, which changes the grid spacing of the pipette tips. After three full iterations, the final design utilizes two 1/8" stainless rods in both lateral and longitudinal directions to support 96 resin 3D printed carriages. Pipette tips attach below the carriages and tubing is connected on top to syringes for pressure build up. The rods are supported on both ends by bearing carriages, which ride on square aluminum rails and are spaced by their width (closed configuration) and by limiting straps (open configuration). The device is customizable for the lab users based on the spacing of rack and well plate that is being converted, and each of the approximately 400 individual pieces can be easily serviced or replaced. |

Steering Rack and Pinion
for Blue Jay Racing 17XT, 2020 The steering rack and pinion converts the driver's torque on the steering wheel to linear force onto the tie rods to steer Blue Jay Racing's vehicle. After reviewing the past 5 years of the team's rack design, I determined the major previous design failures and recalculated the steering system's loading conditions from experimental strain gauge data. Major changes from previous years include the support tube to eliminate sleeve bearing alignment, 33% weight reduction due to the new bimetallic rack, and an ergonomic 210 degrees lock-to-lock steering angle. Designed and analyzed in Solidworks for desired FOS 2.0 and expected 50-60 hour lifetime. |

COVID Testing Vial Uncapping Machine
for University of Minnesota Genomics Lab, 2020 During the Fall 2020 college semester, the University of Minnesota tested each student and on-campus affiliate for COVID-19 on a daily basis, which resulted in approximately 1.5 million tests per month. To automate the process of uncapping the received vials, we created a machine to fit under a fume hood and process 96 samples at a time. I designed and tested numerous 3D printed gripper designs to slide down over the caps, latch underneath a lip, pull the cap off the vial, and dispose of the contaminated object through flexible tubes and down a main chute. Towards the end of the entire fabrication process, the Genomics Lab needed to switch to screw top vials, so I brainstormed an alternating lead screw to unscrew 12 caps at once. After creating a full prototype, I optimzed the final version to reduce friction and be fully sealed from any airborne contaminates. |

Mini Crane Boom Design Project
for Mechanics Based Design Laboratory, 2020 Working with two other mechanical engineering students, I worked to calculate loads, determine factors of safety, design the beam and a transmission system, CAD, and select materials for a small crane intended to lift 10 pounds at 18 inches off of a table. Unfortunately, we were unable to construct the final design due to the COVID-19 school closure. Click here to view the assembly drawing and component list of the crane. |

Brake System
for Blue Jay Racing 16XT, 2020 As Controls lead of Hopkins Baja, I designed the entire brake system, which includes the pedals, bias bar, master cylinders, brake line, calipers, and rotors. Following the goals of the overall vehicle, some components are off-the-shelf for easier manufacturing and serviceability. I utilized Solidworks to design some components, perform FEAs, and package the parts into the larger car assembly. Click here to view my presentation on the system. Read More
Goals - The goals of the 16XT brakes are to provide a reliable system to pass brake check, accommodate the additional 4WD components in the footbox, and to improve load verification of the system. Data Collection - Instead of simply estimating like in previous years, we conducted tests to more accurately define our loading conditions. For example, we experimentally found the coefficient of friction between caliper pad and rotor to be 0.31. With numerous inputs, including a desired factor of safety above 2 for both front and rear brake lines, the system requires 3000lb-in on the 16XT rotors to pass brake check. Design - The 16XT pedals are simple and easy to manufacture, floor mounted this year to improve driver visibility and reduce their profile. Rather than last year’s custom calipers and master cylinders, which led to manufacturing and performance failures, we switched to off-the-shelf components. Packaging constraints drove the selection of both the Wilwood MC Karts (0.5in bore), a reliable and small model that Blue Jay Racing has used in the past, and the Polaris Sportsman Calipers. Improving weight reduction over last year’s rotors, a leading spoke cutout design decreased moment of inertia by 4%. Both the rotors and calipers are mounted to axially float into the path of least resistance. Analysis - With the collected data and well defined loading conditions, FEAs were conducted on the manufactured pedals and rotors with 100lb applied at the pedal, creating 3000lb-in on the rotors. Validation - We conducted several brake checks with the system assembled on the car, simulating the competition event. Bleeding the 3AN brake lines to obtain sufficient incompressibility of the DOT3 fluid was a challenge, so we placed pressure gauges on each line to verify when we obtained 750psi in the rear line and 1400psi in the front due the driver pressing on the pedal. With an almost complete brakes testing rig, we can confirm the torque to turn the rotor at certain pressures. |

Center Driveshaft
for Blue Jay Racing 16XT, 2020 With a major rules change for the 2020 Baja SAE competitions, the Blue Jay Racing team switched to a 4WD vehicle for the first time in history. I took on the role of designing the car's center driveshaft, which provides power to the front differential from the transfer case. We will splice and extend a Polaris driveshaft, covered in SAE rules compliant casing for both the shaft and joints. |

Automated Sensor Resistance Tester
for FreshAir Sensor, 2019 FreshAir Sensor makes patented devices to detect tobacco and marijuana smoke in hotels and apartments. After printing the chemical solution on each plate, the resistance must be tested on all of the manufactured sensors. The device pictured clamps down onto the plate of sensors and contacts them with spring pins. PCB board (which I did not make) connects to an online portal and indicates which sensors are outside of the desired threshold. The device automates the process of testing each sensor with a multi meter to reduce manufacturing and production time. |

Aerospace Fastening: Bolts & Rivets, Welding, and Adhesives (2021)
Whether joining spacecraft structural members together or attaching skin to the wings of an airplane, it is critically important to consider all possible fastening methods available; choosing the wrong one could result in thermal or structural failure. This paper investigates three common types: bolts & rivets, welding, and adhesives within aerospace applications. Bolts are exceptional at connecting structural frame members, rivets are low profile and great for shear lap joints, welding offers a leakproof and mechanically sound joining option, and adhesives are best for hybrid joints and distributing the load over a larger area. |
Material Design for Acoustic Loads of Spacecraft during Launch (2021)
Spacecraft encounters numerous loads, including acoustical ones which emanate from the engines of the vehicle. These cause the material structure to experience acoustic fatigue, which is often difficult to predict. Payload design has been modified using material with increased acoustical absorption and reflection such as composite fibers. Future developments in the field involve using shot peening on oxidation coatings to increase the fatigue life of aerospace aluminums. |
Twisted Ribbon Geometry and Design (2020)
This paper is written for the Antioch Recovery Project, part of the Classics Research Lab at Johns Hopkins University. It serves as a journal surrounding my research into the Twisted Ribbon border pattern of the Antioch Mosaics, a meandering flat ribbon waving across the mosaic in a repeated manner. While there is thought to be no major significance to the pattern itself, it represents “the movement towards ornamental complexity” in the Antioch mosaics, “which was born in the late second century.” This paper will focus on the twisted ribbon that transverses sinusoidally, analyzing the pattern in a geometric, design, and mathematical context. |
Hedonic Price Model of New England Ski Areas (2019)
Using a database of 60 New England ski areas, the correlation between several primary resort characteristics and the 2018-2019 adult day ticket prices is analyzed. A hedonic price model is used to run an OLS regression on the data and determine the importance and significance of 13 variables. This study determines that ski area size (including number of trails, skiable acres, and vertical drop), the snowmaking capabilities of the mountain, the number of nearby restaurants, and the proximity of a ski area to local residents and population centers have the greatest positive influence on ticket price. The hedonic model is also used to form a ranked list of ski areas in New England by their expected ticket price, representing resort quality, and how this compares to their actual ticket price, representing resort value.This study can provide valuable information to ski area management and tourism offices across New England, who can better understand the motivations for alpine skiing customers in the region. |
Trump Twitter Discourse (2019)
Donald Trump, the Republican Candidate in the 2016 United States Presidential election, used Twitter to insult and troll his opponents, particularly Democrat Hillary Clinton. By looking at 230 @realDonaldTrump Tweets which address Clinton during the campaign, this study analyzes Trump’s statements sociolinguistically and statistically, comparing the tweets’ structure and rhetoric between two time periods. Once Clinton became his primary opponent, Trump’s tweets became slightly more multimodal, the number of tweets addressing Clinton decreased, and the average length of these tweets also decreased. However, there was no significant change in Trump’s rhetoric toward Clinton. Further analysis reveals that Trump’s shorter tweets gained more popularity, as well as statements referencing Clinton’s email scandal. These comparisons and linguistic analyses of Trump’s statements provide insight into his communication process and campaign strategy during the election. |

Computer Modeling
Flying Ring Optimization
for Design and Analysis of Dynamical Systems Final Project Spring 2021 We focused on the steadiness of a flying ring in order to maximize the distance it will travel. After researching the governing aerodynamic properties and relationships, we created equations of motions for the flight. Our MATLAB model incorporates the initial and iterated angle of attack of the disk into the distance calculation. We optimized for distance by varying radius and mass of the disk, averaging many throws across initial angle-of-attack angular position and velocity. We found that the radius of the disk does not have a significant effect on the flight and distance is maximized when the disk is 0.5kg. Click here to view the project report and code. |
Beam Stress and Displacement Analysis
for Extra Credit Mechanics Based Design Class Project Spring 2020 The goal of the project was to model a beam of any material and shape to calculate the maximum stress and displacement due to any forces or point moments, constrained as a cantilever or by a pin and roller. A partner and I implemented the model in MATLAB using the singularity function method and calculated approximate Von Mises stress. Click here to view the project report and code. |

Photography
Ever since I was 5, I have always been intrigued by a camera. Always striving for that perfect shot to tell the story in front of the lens. I have found that photography has abilities that humans lack; being able to slow down time or completely freeze it cannot solely be done with human eyes.
