Class project at UC Berkeley for ME C278 - Designing for the Human Body. As part of a team of 5, I designed and prototyped a rehabilitation device for patients suffering from muscle contractures.
My work included the design of a ratcheting mechanism to provide measurable and repeatable range of motion for the device.

Iterative Design
I worked on several projects Computer Aided Engineering (CAE) projects during this Summer internship with Ashok Leyland, India - the 4th largest manufacturer of buses in the world.
As a part of my time with the CAE team, I performed topology and lattice structure optimisations on new and exisiting vehicle components to achieve various optimisation targets such as natural frequency improvement and compliance reduction.
I communicated these optimisation results with design engineers and provided suggestions for improvement and new avenues of exploration of the design space.

Finite Element Analysis
Overview:
I worked on this as a side-project at the University of Illinois at Urbana-Champaign. We built building experimental hardware models for scaled-down electric propulsor arrays. These arrays were tested in a 3’ x 4’ windtunnel at the Aerodynamic Research Laboratory, Urbana, IL.
Skills Used:
• Solid Modelling
• Rapid Prototyping
• Engineering Analysis

Overview:
This was a year-long project during my undergraduate degree. I led a team of three to design and fabricate two solar collectors. To be precise, they are discrete-parabolic solar-thermal collectors. During this project, my peers and I worked with some 500 kg of various metal parts. We designed jigs to speed up the drilling process of aluminium support beams. The energy captured by means of these collectors was utilised in a dessicant-based evaporative cooling system.
Skills Utilised:
• Engineering Design
• Finite Element Analysis
• Design for Manufacture
• Solid Modelling
• Metal Fabrication
• Design of jigs and fixtures

Overview:
I spent one academic year with Pegasus Racing, PSG College of Technology’s student formula team. We designed and fabricated the team’s fifth functional car with a kerb weight of 232 kg. My role as a powertrain engineer involved powertrain intergration and maintaining powertrain CAD models. In the end, our car ranked 13th overall out of 121 participants in the 2015 SUPRA FSAE India event.

Overview:
This was a final project for a topology optimisation class at the University of Illinois at Urbana-Champaign. Along with three others, I developed a MATLAB program to optimise the topology of a design domain, given some boundary conditions. The program utilises the finite element method to solve the forward problem, and density filtering and gradient based parameter optimisation. The gripper was able to lift a load of 7kg without failing!
Skills Utilised:
• MATLAB
• Topology Optimisation
• Finite Element Analysis
• Rapid Prototyping
• Solid Modelling

Practising some machining and making sure I don’t lose touch with G-codes in my free time!

Being a tropical creature, I am currently working on an effective solution to wake up on cold Fall/Winter mornings. I am also using this project as an excuse to teach myself to program Arduinos and Raspberry Pis.
Overview:
I want to stimulate the body’s natural wake-up response to the break of dawn by increasing the body’s core body temperature and gradually increasing the intensity of light falling on the eye-lids. Essentially, this mimics sun-rise and makes waking up much easier!
I used a Raspberry Pi (RPi) to interface with a smart-phone through a webpage so that the user can set the wake-up time. The RPi acts as a timed switch to turn on a heated mattress pad and an array of LEDs.
Skills Utilised:
- Raspberry Pi (Python)
- Networks and Wireless Intefaces
- GPIO control
Taking time on Sundays to learn a much overlooked trade!
Overview:
During the final semester of my undergraduate program, I interned at the Indian Space Research Organisation (ISRO). In particular, I worked with the Thermal Systems Group at the U R Rao Satellite Centre (URSC) [formerly known as ISRO Satellite Center (ISAC)]. During my time there, I developed a computational module in C along with a classmate of mine. We wrote a program to calculate the view factors (a quantity essential in radiative heat transfer calculations) between obstructed surfaces. I presented this work as my Bachelor’s degree thesis. Moreover, our work was also presented at an international heat transfer conference the following year.
Skills Utilised:
• C Programming
• Numerical Methods
• Heat Transfer

Overview:
This is part of my work as a research assistant at the Aerodynamics and Unsteady Flows Research Group (AUFRG). In less than six months I developed a novel algorithm to decompose multidimensional and multivariate signals using a technique known as empirical mode decomposition. My research advisor and I authored a paper detailing the algorithm, which was published in the IEEE Signal Processing Letters. The latest version of this code can be found here. The program is being utilised to decompose various dynamic phenomenon encountered as part of the AUFRG’s research.
Skills Utilised:

• Digital Signal Processing

I did not have the heart to scrap a used brake disc. So, I turned it into a clock!
A parting gift that I made for a mentor.
This is just a rough sketch of an idea that I had before I realised that Gillette had already patented it.
I was tired of having a the First In First Out (FIFO) problem with clothing in my wardrobe, so I came up with a possible solution. The conveyor system is intended to travel by the of the imbalance in weight of each pallet. Thus, creating a Last In First Out (LIFO) stack and ending the monotony of your wardrobe!
An attempt to measure the viscosity of household fluids for a class project. Inspired by French physiologist, Jean Léonard Marie Poiseuille whose experimental results are lauded for their incredible accuracy given their age. (More details in the report)
Always looking for an opportunity to do a quick build!
