I joined Raman Research Institute (RRI) as an Engineer with the primary goal of conducting scientific experiments using the engineering background I acquired. During my stay at RRI, I flourished in an environment full of resources and imbibed the engineering culture most essential for my profession from the professionals I worked with. I worked on several engineering problems encountered in the fields of radio astronomy and experimental cosmology. I feel it is a great honour and privilege to share the work I’ve done over the past thirty three years with everyone.
