Research Interests

I work in the field of precision observational cosmology. Science focus of my research is to peek into the past and understand the evolution history of the Univserse using redshifted 21cm cosmological measurements.  My current research activities are (1) CMB spectral distortion measurements at low frequencies to detect the spectral signatures of the Global 21 cm signal from the Epoch of Reionization (EoR) and the Cosmic Dawn (CD), (2) Developing novel radio astronomy techniques for this challenging measurement, (3) Characterising the instrument and foreground interactions in power spectrum measurements. As an Electronics and Telecommunication Engineer I work on multiple aspects of my projects including radio telscope design and optimizations, theoretical modelling, developing statistical RFI mitigation technique and data analysis. I am also keenly interested in space based redshifted 21~cm observation and my current research is lays the roadmap of future redshifted 21~cm space mission by providing the ground based science and technological concept study. 


Personal Interests

I grew up in Kolkata, one of the oldest city of India and lived in Bangalore for 6 years during my gradschool. Both these cities that have unique cultural and academic identities groomed me all through. Following my childhood learning from various music schools in Kolkata, I received my first formal training in Hindusthani Classical music from Smt. Ratna Sharma, daughter of the musical maestro late Pt. Shankar Lal Mishra for six years in Bangalore. I am currently a student and a member of the "Vasundhara Choir" of Smt. Rita Sahay, a senior disciple of Sangeet Samrat Ustad Ali Akbar Khan. If you are in the Bay area and interested in Indian classical music, information on Smt. Rita Sahay, her Vasundhara Coir and our upcoming concerts can be found in http://ritasahai.com/events/ .


Biography

I am a Postdoctoral Fellow at the Radio Astronomy Lab, New Campbell Hall. Before my current position, I earned my PhD in 2015 at the Raman Research Institute, Indian Institute of Science, India while working with Dr. Ravi Subrahmanyan. I was a co-supervised PhD student at the Australia Telescope National Facility (2012-2014) with Dr. Ron Ekers who was my PhD co-superviser. I received a B.E. in Electronics and Telecommunication Engineering in 2007 from Indian Institue of Engineering Science and Technology , Shibpur (erstwhile known as Shibpur B.E. College) and worked as an Associate System Engineer at the IBM from 2007-2008 before joining my PhD.
