2. About Me
I am a sixth-year aerospace engineering
student at Cal Poly Pomona. I anticipate to
graduate in May of 2021. I am in search of an
aerodynamics internship to apply the
knowledge I have already learned through my
projects to a real-world application. This
portfolio is a collection of projects which I
have led or been a part of during my time at
Cal Poly Pomona.

3. Senior Project (pt. 1)
For my Senior Project, I performed duties as design lead, aerodynamics
lead, and deputy lead. My primary tasks were to design 15 wing/winglet
configurations, perform CFD analysis, and oversee the testing of the
parts.
Below is an example of the static
pressure analysis performed on
one of the wings. This was
performed using ANSYS Fluent to
predict the wind tunnel
performance
Above is an example of one of the wings.
The wing was modeled in such a manner
that the winglet sizing determines the
sizing of all the other parts through a
mix of equations and dependencies

4. Senior Project (pt. 2)
During my time with the project, I also worked with an industry expert
with other 30 years of manufacturing experience with composites to
produce all the wings and winglets.
In the above photo, I was
preparing pieces of fiberglass to be
used in making the fiberglass
molds of each part. To make the
molds, 3D printed models of the
wings were created and wrapped
in multiple layers of fiberglass.
Both epoxy resin and gelcoat were
used to ensure a clean, reusable
finish on each mold.
In the photo below, I am placing
the layers of fiberglass used to
create the molds with the help of
an industry expert (in the
background of the photo). Support
beams were used to keep the parts
stable while the resin cured.

5. Senior Project (pt. 3)
Below is a picture of the forward swept wing with a split winglet
attached to the end. The orange tuffs were used to show the
approximate air flow as a means of validating the PIV data collected.

6. New Member (2017-2018)
Designed and manufactured race box for Formula
SAE competition use.
I designed the handle
quick release system
as the bracing system
for the toolbox.
Below, I am welding
the baseplate for the
toolbox shelf to the
frame.

7. New Member (2017-2018)
Designed a composite heatshield to tightly fit the
exhaust system for the 2018 FSAE vehicle

8. New Member (present)
Full remodel of 2019 vehicle for use in CFD analysis
as the old model files are corrupt and out of date.
The new version has far higher detail than the
previous model, and therefore should yield more
accurate results.
The remodel is
necessary as the full
vehicle model is far
too complex for
meshing.

9. New Member (present)
Below is are examples of the CFD model. The
analysis was performed at 60 mph with a rolling
road and wheels simulated.

10. Current projects
Endplate redesign to maximize performance by
reducing strength of vortices from the wing
elements and tires. This will lead into the
implementation of a DRS system.
Also adding an
extra lower
element to
maximize rear
downforce.

11. Particle Image Velocimetry
Project
Served as CFD Technical advisor for the team. I am
responsible for performing CFD analysis on the
desired models as well as train the team members to
perform analysis as well
Above is the velocity plot for the “black wing” model
used by the PIV team for calibration. This data is
used as a reference for the team to see what
velocities the PIV system should read.

12. Northrop Grumman Collaboration
Project (pt. 1)
During my time with the team, I served as a general
member as well as the Testing lead. With the
project, I aided in the design of a blended wing
aircraft, performed stability analysis, and generated
the testing procedure/schedule for the project.
Below is the blended wing aircraft I helped design
for the 2018-2019 academic year. For this plane I
developed a matlab program for initial sizing then
performed aerodynamic and stability analysis.

13. Northrop Grumman Collaboration
Project (pt. 2)
The code I developed takes the basic parameters as inputs
and generates numerous plots through the different GUIs
shown below. Sliders were included on the graphs for
adjustment
The data can
then be used for
further
calculations as
well as modeling

14. Stefan Stocktracker
Below is are screenshots of interaction with a
discord bot I developed, named Stefan, that detects
the text in each dialogue and can track the value of a
stock. Once the stock reaches a specific value, Stefan
sends a direct message to the person who requested
the information.
