This is a non-exhaustive list of some of the projects I have worked on since 2015.

Tackling Climate Crisis: Learning from CoVID-19

As a part of the Swiss #VersusVirus hackathon, I worked with a team of Climate Researchers across the world to better understand how we can adopt our learnings in handling the CoVID-19 pandemic to the biggest threat currently facing the human population. We compile our thoughts and suggestions into a presentation report available here.

Wikilimo - Open Climate Informatics

Wikilimo is an online-offline platform for hyperlocal weather and agri-insights built as a submission to the United Nations Summer of Solutions program. It analyses citizen science data and satellite imagery to provide actionable insights on agriculture, climate and finance to farmers in remote communities with limited connectivity.

As a collaborator for the OpenSuperQ project (an EU initiative to build a 100 qubit open source superconducting quantum computer), I have helped develop a software for fast calibration & characterisation of quantum devices. Specifically, I benchmarked a suite of gradient-free algorithms used for optimizing the Qubit Control Microwave Pulses. I also helped build APIs for integration with Qubit Control & Characterisation modules.

At Chubu Plant Services, we designed a fully automatic polisher for industrial fittings as demonstrated in this video. I programmed a Mitsubishi MELSEC Fx3U-48M PLC, wired up the mechanical and electrical components and prototyped the above design. I introduced fail-safe interlocks and developed a pseudo-pipelined algorithm that reduced per bolt polishing time. You can read a brief report here.

This is a 300MHz 50-50 Beamsplitter developed using Lange Coupling and fabricated as a Microstrip on Epoxyglass. A 4.5 dB coupling was reported and the losses are equal in both the output ports which have same energies. It was designed and simulated in CST Studio and fabricated in-house at RRI. It has application in MW Quantum Optics and the details are available here.

For my Bachelor's project, we built wearable gesture-recognition modules for patients with movement and speech disabilities. It uses Electromyography to detect tapping of fingers or turning of the wrist as well as complex motions such as drawing an alphabet in the air. My thesis was on portable pattern recognition of EMG signals. (Image from here)

This is a block diagram of an 8-bit processor coded in VHDL that can be programmed for general purpose use. The Instruction set is a set of 8 items comprising input, output, assignment, operations & jump. There is a separate program memory for when the processor is being used for some particular application e.g, temperature control or chronometer. Check the code here.

One of the much-hyped capabilities of Quantum Computers is their ability to crack current cryptographic protocols. But Quantum Cryptography is also subject to eavesdropping by tampered devices. Here, I study a few protocols that use Bell-type Inequalities to tackle the problem of Device-Independence. You can read a quick report here.
