As an LSAMP scholar, I started doing research under Prof. Robert White who specializes in microscale sensors and systems. Since the beginning of fall 2018, I have been learning MEMS fabrication techniques. That semester, I worked in the Tufts nano and micro fabrication facility, and I focused on processing several cMUT wafers. I was trained on protocols for working in a cleanroom, how to operate several micromachining tools, and several processing techniques such as sputtering, lithography, evaporation, plasma etching, etc. 

Microelectromechanical systems (MEMS)

Martian Ultrasonic Anemometer

During the summer of 2019, I worked on a Martian Ultrasonic Anemometer project under Prof. Robert White. The point of this project was to develop a system that could accurately measure wind speed on the surface of Mars. I did some of the more mechanical aspects of this project. I helped in 3D printing and machining of several of the parts in the assembly. A peer-reviewed conference paper has since been written and can be accessed below. This project was also presented at the AIAA SciTech 2020 conference in Orlando, Florida.

During the fall semester of 2019, I have been working on an updated version of the previous Martian Ultrasonic Anemometer. I have been designing something that will be lighter than the prior version. I used SolidWorks and Fusion360 to do the modeling of the structure and doing simulations. This project is currently in the works and I have been testing to see what material is best to use such as VeroClear (a translucent Polyjet resin) or Onyx (a single composite containing nylon and chopped carbon fibers)

Visualizing Audio Data with Animations

During the summer of 2020, I participated in the Tufts T-TRIPODS Institute Summer Data Science Program. I worked with Prof. Intrilligator and another student in this project. The goal was to be able to find ways to visualize complex sets of audio data. We provided JavaScript code and implemented the use of "shaders" through p5.js and shadertoy.com resources to provide visuals for when microphone data from one's computer is picked up. 

In order for the code to use your microphone, you will need to expand the graphic displayed on the right.

Soft Robotics

During the summer of 2019, I also worked in a different lab with a student-led group. The project was to create a vest that could help correct a person's posture by means of soft robotics. I helped work on a Silicon 3D printer, where I did some PCB design work for it. I also helped make some silicon casts and did several silicone molds. 

Health Monitoring via Guided Based Waves

In the summer of 2018, I participated in the Shanghai Jiao Tong University Summer Research Internship Program. I worked in a mechanical engineering lab doing structural health monitoring via guided based waves. I used Abaqus 2016 to model and do FEA simulations for a steel plate structure. I then used an actual steel plate and actuators to run the same test to compare the results between the simulation and experiment.

Class/Group Projects

Instruments & Experiments:

Final Project

In the class, Instruments & Experiments, for our final project we created an experiment to track muscle fatigue via pose estimation and body movement. We did this by employing DeepLabCut software to track an individual's limbs and joints as they attempt to hold a certain position over time. Pose and fatigue estimation have already had some correlation due to past research papers using motion analysis with rehabilitation exercises. Evidence was shown that fatigue influences and alters the kinematics of movement in a person as they did exercises/tasks. The purpose of our study was to look further into if people show similar fluctuations in movement as they start to experience fatigue while holding poses

Senior Design Project:

Metal 3D Printer for Space

Douglas Matson, the team’s client and a research professor at Tufts University, is collaborating with NASA engineers to develop a novel 3D printing system for space. The design team’s objective was to assist engineers at NASA to design a small scale, powder based metal 3D printer that can sustain the zero-g environment and fit into a NASA Nano-rack CubeSat module, to future support astronauts in manufacturing required metal parts when needed.

Our scope provided a simplified version of the initial workflow provided from our client in our prototype. Our focus was to make our prototype modular enough to easily integrate those components in the future. The final solution provides the basis of a metal powder ink 3D printer that has the basic functions and subcomponents for an effective way for astronauts to produce parts and/or tools in a zero-g environment.

Intro Human Factors:

Designing Tufts Mobile App

In the class, Intro Human Factors, for our final project we redesigned the Tufts mobile SIS (Student Information System) website into an app. Our group used surveys, heuristics, among other UX/UI techniques to develop a product that was more user friendly to the student population at Tufts.

Intro to Computing in Engineering Science: Final Project

In the class, Intro to Computing in Engineering Science, we focused on developing coding skills in Matlab. We did a variety of assignments and we were able to choose our final project. I developed a program that does pendulum simulations. I created a GUI (graphic user interface) for users to adjust the mass, gravity, damping constant, and length of the string of the pendulum. The program then simulated the two pendulums and graphed the oscillations.

MAKE Project:

Giant Galton Board

I am a member of Tufts MAKE, which is a club where students collaborate and tackle different design/engineering challenges each semester. I worked on a giant version of a Galton Board. These boards are a means to demonstrate normal distribution. As you rotate the Galton Board on its axis, you set into motion a flow of balls that bounce with equal probability to the left or right through several rows of pegs. As the balls accumulate in the bins, they approximate the bell curve. I did some of the initial design work and helped put some of the parts together. 

Simple Robotics:

Shoot-Tac-Toe

In the class, Simple Robotics, my partner and I developed a game for kids to play that is a spinoff of tic-tac-toe. We used Lego Mindstorm parts to make the toys, which shot ping pong balls into a 3D tic-tac-toe matrix. The kids were also able to adjust the speed and angle of the shooter. The final product is shown in the video to the left.

We made several other contraptions/robots using Lego Mindstorm parts and python code. This is just one out of several. Click here to find more of the robots we made!

Mechanical Design & Fabrication:

Electronic Wand Twister

In the Mechanical Design class, my team created a product so that Tufts students could control the light in their dorms by means of an electronic wand twister that attaches to the wand already in the window sill. Our group went through the engineering process for this project. Through ideation techniques, we created a problem statement, house of quality, and several prototypes.

 

We then presented this project to our peers.  You can click on the picture to the left to see the full poster.

Food For Energy Project

Engineering Management:

Anaerobic Digester

In my engineering management class, we worked on a semester-long project that could improve the Tufts campus. We pitched our idea to the class and Tufts' environmental board. We proposed an anaerobic digester that would convert food waste into energy. Throughout the semester we also learned how to work in a cross-functional team, how to develop work breakdown structures, Gantt charts, risk matrixes, budget proposals, etc.

The final presentation can be accessed here.

Computer-Aided Design:

Final Animation

In my computer-aided design class, we used several Autodesk software such as AutoCAD, Revit, Inventor, and 3DsMax throughout the class. Our final project was to create a final rendered animation. I chose to do a "wacky" factory assembly loop sequence.

As a member of the Tufts Trading Fund club, we separate into sectors/subgroups during the semester. Each sector has a different focus like Emerging Markets, Derivatives, Commodities, etc. In each sector, we develop pitches for specific stocks that we have done research on.

 

Several pitches that I have worked on are on the left. Click on any of the pictures to view the full presentation.

 

Personal Projects

Halloween Daft Punk Helmet

I designed a replica helmet of one of the artists in Daft Punk. I 3D printed the majority of the parts using Fusion 360 and SolidWorks. I then cut and tinted the plastic screen to make it the right shape and color. I also added some LED's that change color depending on the setting.

Arc Reactor Lamp

I designed a lamp based on Iron Man's Arc Reactor. I used AutoCAD and Inventor for this project. I am still waiting to put the actual pieces together for the real-life lamp.

Gyroscopic Bike Cup Holder 

I made a gyroscopic cup holder that can attach to a person's bike. I modeled the main parts in Fusion 360 and 3D printed them out. Screws hold everything together. Once it is attached to the bike, the holder should mitigate the majority of the bumps so that there are no spills.
