I completed my Ph.D. in 2004 at ARIES, Nainital, and TIFR, Mumbai, India, with a focus on the search for microlensing events utilizing the pixel method. My doctoral thesis, titled 'Search for the Microlensing Events using Pixel Method,' was a significant contribution to this field. In 2001, I became part of the Indo-French project, specifically the Nainital Microlensing Survey. Here, I conducted an extensive photometric survey of the M31 disk using a 104-cm telescope to identify microlensing events. I played a key role in developing a reduction pipeline for the 'pixel analysis' technique, enabling the identification of optical transient events in the photometric data. This effort led to the successful detection of a microlensing event in the direction of the M31 galaxy. During the period of 1997-1999, I was actively involved in site characterization at Devasthal, Nainital, as part of the initiative to establish a 4-meter class telescope at the location. In the course of the Nainital microlensing survey, I contributed significantly to the detection of variable stars, particularly Cepheid variables. The use of these stars, with their well-known period-luminosity relation, proved invaluable for determining the distance of the host galaxy. Our photometric monitoring of M31 spanned four successive observing runs from October to January each year. Taking advantage of this extensive timeframe, we conducted a thorough search for novae erupted in our target field during the same period. Over the course of our four-year survey, we achieved notable results, including the detection of one microlensing event, 26 long-period Cepheids (P > 7.5 days) using DAOPHOT photometric technique, 39 low-period Cepheids (15 > P > 3.5 days) using the pixel technique, 2 classical novae, including one fast nova, and the identification of more than 300 variable stars in the M31 galaxy.
