My goal as a mechanical engineer is to glorify God through benevolent, quality engineering practice.

Improving Indian Beehives and Beekeeping
Problem: Smaller entrances help bees defend the hives but hurt ventilation.
Model: I have used CFD to model 100+ entrances to categorize ventilation effects.
Test: I rapid prototype and test entrances to gain key understanding of what works best.
Problem: Indian beehives are often painted dark colors absorbing sunlight.
Model: CFD shows that heat is wicked away on the edges and corners.
Solution: Edges and corners can be any color, but faces should be white.
Problem: Hive manufacturing in India, while less expensive, has less quality control.
Evaluate: I performed a factory analysis of 30k boxes / yr manufacturer.
Share: I have suggested practical improvements for the official Indian hive standard.
Summer 2014 - January 2016
Sponsored as an MIT Tata Fellow
, I used mechanical engineering to improve Indian beehives. The work delved into fluid dynamics, manufacturing, and mechanics, and I focused on the low-hanging fruit / highest impact items for Indian beekeepers.

Loop Control: Laser Light Show
Fall 2014 For a graduate mechatronics course, I stabilized two galvanometers from a prebuilt rig. I used feedforward lead-lag control to direct the laser to draw geometric shapes with minimal overshoot using Labview.
Spring 2014 I spent one semester with the Hover Research Group researching backdrivable robots using the Baxter with the goal of underwater use.
Intro to Architecture
To graduate from MIT a semester early, I took a studio based arts class that explored designing across scales with nature as inspiration. See my portfolio page
Engineering Balance Conceptually
I wrote my senior thesis on how to engineer systems requiring balance, especially with humans. Human balance is unpractical to clasically model, and so I derived a conceptual framework that isolates three mechanisms used to control one's motion. Read the thesis
2.009 Product Engineering Process (Senior Capstone)
The team of 19 made a navigational heads-up display for motorcyclists. I led 1) external and internal development of the Android app and 2) user input. Placed first out of eight teams. See the team presentation
Verilog Brick Breaker Game
With a partner I made a brickbreaker game that used camera input to move the paddle. This was made using all digital logic (hardware)! See the report
or watch the video
Voice Controlled Poker Game
Fall 2013 Our foursome laid down a working voice-controlled poker game proof-of-concept. I coded a round of betting logic in php interfacing to an external call recognition service. Included was a custom HDTV poker table to feature our original realtime rendering and a 52-page report. We had gone all-in for quad aces.
Automated Test Stand
At Vecna in Cambridge, MA, I designed and coded an internal application to test and calibrate hydraulic robots. The Python and Tkinter application improves the efficiency and safety of Vecna's engineers and technicians with real-time graphs of sensor readings, integrated calibration and data collection reports, and extensibility for endurance testing.

Study Abroad at Cambridge University
Spring 2013 During studying abroad at Cambridge University in England, I completed two team projects: a bicycle design project and a CAD/CAM project. The bicycle design project used fatigue analysis to determine the lifetime of bicycle handlebars and the CAD/CAM project introduced me to Creo, Abaqus FEM, and PowerMILL. (At MIT I have used SolidWorks and MasterCAM.)
2.008 Design and Manufacturing Yo-yo Project
Fall 2012 My team of eight designed an impressive yo-yo for which we created the molds and then injection molded / thermoformed. The center white gear spins freely.
2.671 Go Forth and Measure: Improving the Shape of a Jump Rope
I measured the shape of a jump rope and tested what happens when small weights are added to offer more width at the bottom. Read the report

Haptic Research at CINVESTAV's Mechatronics Group in Mexico City
Summer 2012 My Mexican partner and I compared two haptic (or touch) teleoperation interfaces. I designed the experiment, coding our Android remote control application with vibrational feedback to compare to his master robotic arm with force feedback. Concluded with a 30-minute oral presentation in Spanish.
2.007 Design and Manufactoring I
Spring 2012 I designed and manufactored a scissor lift robot to lift a slug. The robot fared alright and I gained experience with all the tools in the shop.
I worked at AirVentions Inc.
, a startup in Boston that makes collision avoidance systems. I worked in SolidWorks and helped to design the enclosure for the sensors. In a 12-page internal report, I presented four SolidWorks models for the enclosures, detailed the manufactoring and marketing benefits of my most recommended design, and outlined design requirements for future engineers.
Autonomous Line-following Robot
Fall 2011 With my partner Daniel Gonzalez, we won first in our 2.S994 Electronics for Engineers class of 30 MIT students for fastest time.
Technical Writing Class
Fall 2010 In my technical writing class 21W.732 with Prof. Dave Custer, I discovered I liked technical writing. I also liked that the projects became featured on MIT OpenCourseWare as examples.
My partner Kristina Johnson and I designed a dynamic speed bump. The idea was to save energy by letting nonspeeders pass at the speed limit, but catch those who speed. Report
Nolan Essigmann, Lilian Guevara, and I built and wrote about solar water heaters. Report
