I was the lead engineer for the development of a real-time closed loop control system for the AOsystem. My responsibilities in the project were as follows:-1. In an AO instrument, a control system is used to extract the Shack-Hartmann WavefrontSensor(SHWFS) signals and compute the signals that are to be sent to the Deformable Mirror(DM). This is a compute intensive task, as the new DM feedback signal is computed from the raw SHWFS frame data typically at 1KHz rate. We worked on two-PC control system architecture in this problem.2. We developed an emulator for an AO closed loop control system. We used Webcam cameras and Arduino boards to program them such that their properties(like data transmission rate, data type etc.) resemble actual AO subsystems like SHWFS, DM and TTM.3. I had written C++ codes based on a multi-threaded scheduling algorithm for a real time closed loop control system. The scheduling policies of the operating system were adjusted to suit the needs of our application.

1. Development of a computational test bench – which is a computersimulation package with theoretical framework of AO system2. Setup of a laboratory hardware experiment where various concepts developed in thecomputational test-bench were verified3. A hot-air based turbulence generator was developed by me to mimic atmospheric turbulencein laboratory controlled conditions. The setup involved controlling the wind velocity and temperature of the air in order to achieve the desired Fried parameter4. Optical design of Adaptive Optics(AO) based Near Infrared (NIR) Camera instrument for PRL 2.5m telescope

A new instrumentation project to develop an Echelle based Spectro-polarimeter for PRL 2.5m telescope was initiated. My responsibilities in the project were as follows:-1. As a system engineer, I was responsible for synchronization and integration of several subsystems like optical, mechanical , detector, control and software etc.2. I was actively involved in detector system development of the instrument(2 detectors areinvolved)3. Identification of various requirements for CCD Dewar and thermal analysis to find outthe expected Liquid Nitrogen hold time.4. Contributing in the optical design and tolerance analysis of the instrument5. Procurement of several custom and commercially available components

1. Development of motion control system for MFOSC-P instrument2. Laboratory characterization of the several aspects (like optical, mechanical control system related) of the instrument

My task included optical designing, calibration of detector and image processing for various bio-medical imaging experiments.

Banking experiments were carried out in rural Tamil Nadu to explore the impact of social fabric of our society on prevalent economic models. The statistical analysis was most carried out in R.

Mt Abu Faint Object Camera and Spectrometer- Pathfinder(MFOSC-P) is a Camera-Spectrograph for PRL 1.2m Telescope. The Project was initiated in July 2015 and the instrument was successfully commissioned in February 2019. The instrument design is fully indigenous including optical, opto-mechanical, electronics and software.My contribution in this activity is as follows:-1. Conceptual design of the instrument2. Prepared optical design of the instrument using Zemax software3. Carried out tolerance analysis4. Temperature and pressure variation analysis to take care of ambient conditions at Mt.Abu

PARAS is an exoplanet search instrument attached with 1.2m Mt. Abu telescope, which works on the principle of precise radial-velocity(RV) measurement. The instrument is responsible for the first exoplanet discovery from India. I contributed in the project in the following ways:1. Significant contribution in developing and evolving data reduction and analysis pipeline.2. I helped in precise calibration of the instrument3. I contributed significantly in instrument characterization4. I critically analyzed and provided my inputs in maintaining the stability of the instrument.5. Independently carried out observations during several observing runs6. I explored the possibility of monitoring the stellar activity with PARAS data

I worked on the project "Radar Properties of Lunar Geological Units: Block Abundance and CPR of Impact Craters". This project was based on analysis of satellite imagery data. Data generated from MiniSAR instrument onboard Chandrayan-1 was used by me to detect presence of water ice on moon.
