PORTFOLIO
Shown below are some of the most recent and relevant projects I am working on or have completed. This includes some examples of smaller projects as well. The projects shown at the top are the most recent and get older as you scroll down.
NORTHEASTERN UNIVERSITY: COLD SPRAY LABORATORY ( ADDITIVE MANUFACTURING)
June 2021 - December 2021
Supervisor: Dr. Ozan Ozdemir
For the summer and fall of 2021 I worked as a graduate research assistant in the Northeastern University. Cold spray technology is an additive manufacturing process that welds metal powders to surfaces at high velocity. The technology is used to strengthen and repair military vehicles and equipment, from periscopes and airplane panels to next-generation armor—and promises to revolutionize commercial manufacturing. The process can also be used to 3D print parts in desired metals. The cold spray manufactured parts can have even stronger mechanical properties than the metal parts would have if machined normally. My role focused on simulating the behavior of the spherical and irregularly shaped cold spray particles as they are accelerated by the propellant gas towards the substrate. The modeling was performed using Star CCM+ computational fluids software. The simulations being carried out were then experimentally reproduced to allow for comparison. Interferometry was used to characterize hundreds of actual Titanium particles that were then used in experimentation. Parameters of interest in the simulations were measurements such as rotational kinetic energy and impact velocity. The ultimate goal of the project was to determine the advantages and disadvantages of using irregularly shaped metallic particles to improve the efficiency and quality of Cold Spray manufactured devices. This was validated computationally and experimentally.
UNIVERSITY OF VERMONT - MODELING THE DISPERSION AND DROPLET BEHAVIOR OF COVID-19
August 2020 - May 2021
Supervisor: Dr. Yves Dubief
As an honors college member, the capstone of my participation is marked by an honors thesis where you are free to pursue a research interest of your choice. My honors thesis consists of using computational fluid dynamics to model the behavior of COVID-19. This challenge was approached using a high fidelity fluid simulation code in order to characterize the droplet and aerosol dispersion patterns of an infected individual. My focus of the project was to evaluate the feasibility of using low fidelity computational fluids software to describe small scales of turbulence such as those that develop as a result of nose breathing. The low fidelity results showed promise for gaining rapid computational results when waiting isn't an option such as in the case of COVID-19. The results were compared with an extremely accurate high fidelity code known as YALES2.

UNIVERSITY OF VERMONT - IMPROVING THE CURRENT MECHANICAL BI-LEAFLET HEART VALVE
Senior Capstone Design Project
August 2020 - May 2021
My Senior Capstone Design team was challenged with improving the current mechanical heart valve. I worked as the product manager for my own senior capstone design project, I understand what it takes to coordinate and connect all aspects of a project such as requirements, cost and deadlines. Leading this team of mechanical and biomedical engineers gave me great experience in working across disciplines, as it also required working with our client, a cardiology resident at the University of Vermont Medical Center. Our design team consisted of myself, two other mechanical engineers and two biomedical engineers. Current mechanical heart valve designs pose a high risk of clot formation due to platelet activation and hemolysis (red blood cell death), resulting from increased flow gradients and failure to open to 90 degrees. Patients with these implants must then take anticoagulant medication to reduce the risk of stroke, heart attack or other embolism events. Our novel design employs airfoil shaped leaflets opposed to the usual flat or curved geometries. The wing-like airfoil geometry attempts to take advantage of the Bernoulli Effect to help close the leaflets from their 90 degree position. The first half of the project consisted mostly of prior art and preliminary computational fluid simulations. Some examples of our preliminary results and computational set up can be seen below. I was personally very involved in all aspects of the computational fluid dynamic simulations which were performed using ANSYS fluent.
TUFTS UNIVERSITY - DEPARTMENT OF CHEMICAL AND BIOLOGICAL ENGINEERING
May 2019 - August 2019
Supervisor: Dr. Emmanuel Tzanakakis
This project consisted of designing a control loop using MATLAB as well as thread based flexible sensors for artificial pancreas regulation. The flexible sensors were designed to measure glucose levels in order to determine if the STEM pancreatic cells were performing as desired. The STEM pancreatic cells were stimulated using a control loop that employed PID control.
UNIVERSITY OF VERMONT - RESEARCH ASSISTANT IN STUDYING THE BEHAVIOR OF SILVER NANOWIRES
October 2017- January 2020
Supervisor: Dr. Frederic Sansoz
In October 2017 I began work with Dr. Frederic Sansoz, and I worked with him as a research assistant until January 2020. We were studying the deformation of silver nanowire networks to better understand where and why they deform so they can be better implemented into flexible nano-technology. To do so, I was designing and 3D printing experimental molds to be used in the lab in order to create specimens. These specimens are analyzed using scanning electron and Matlab using digital image correlation. The images below show the actual SEM image of the silver nanowire networks as well as visual data taken from experiments, and potential modeling ideas.
AMERICAN SOCIETY OF MECHANICAL ENGINEERS
International Human Powered Vehicle Competition
Created using Solidworks.Â
I am the Chair of Media for the American Society of Mechanical Engineers. This project is for the American Society of Mechanical Engineers Human Powered Vehicle competition. The goal for the project is to create a fast, adaptable, and sustainable human powered vehicle. The design shows the early skeleton for the tricycle, as the design is continuing to be improved and is beginning to be machined. This April our final design will compete in a National competition against many other universities to test speed, durability, and agility.
ASME COMPETITION VIDEO
I created this video after we raced the trike we designed in order to publicize the club.
