Completed the course from Hochschule Karlsruhe as the part of a dual degree program. Thesis: Board Design for Citizen Science Cosmic Ray Muon Detector • Development printed circuit board for a Cosmic Ray Muon Detector using KiCAD and circuit simulation done using LTSpice. • Focuses on the design of two low-cost PCBs with a low-noise amplifier that is able to read out up to 50 diodes in parallel, with the components both machine and hand soldered.

Projects: 1. Thin-Film Based Sensor For Formalin Detection • substrates : glass and Kapton (deposited by RF sputtering) • Electrode: Aluminium (deposited via thermal evaporation) • Characterization-:(XRD). 2. Design for Wearable Blood Pressure Measurement Device • Implemented an algorithm in LabView to obtain Blood Pressure using ECG signals (extracted using AD8232HRM) and PPG signals (extracted using Pulse Oximeter) enabling Cuff-less, continuous monitoring of BP and Heart Rate in real-time.

Project: 1. Android Based Women Safety System • Developed a device to ensure women safety. • Uses voice recognition and a manual button to send an alert signal along with the location and an image. • interfaced various sensors like ADXL, GPS, GSM, camera and an electroshock device to a handheld device and developed an android application using Java.
