About Me

I received my PhD in Physics from Lehigh Univeristy under supervision of professor Joshua Pepper. I am interested in microlensing method of discovering exoplanets and developing algorithms that can quickly analyze and classify microlensing lightcurves and extract useful information from them.
Aditionally, I am an active member of the microlensing subgroup of the Rubin Observatory Transients and Variable Stars Science Collaboration, and have been collaborating on writing proposals for observing strategies that are suitable for science cases like microlensing. I am also a LSSTC Data Science Fellow and have been trained in data engineering, Bayesian statistics, machine learning, image processing, and advance data visualisation.
Furthermore, I am a member of the KELT science team, and I have taken part in sorting and vetting of exoplanet candidates. I have experience working with KELT lightcurves of M-dwarf eclipsing binaries and giant eclipsing binaries, and have used period finding algorithms to analyze these lightcurves.

Research

The full modeling of each binary-lens microlensing event often requires significant investment of human and computing resources. And in the era of large surveys, a fast technique is required to analyze large datasets and determine planetary system candidates for follow-up observations. For that purpose, I develope algorithms to find features in simulated Roman microlensing light curves. This includes features like smoothness of the peak, symmetry, number of extrema, number of peaks, and width and height of the small deviations from the main peak. This will allow us to quickly analyze a set of microlensing light curves and later use the resulting parameters as input to machine learning algorithms to classify the events. My works mainly focuses on Roman simulated light curves, but I am also interested in the synergy between Roman Space Telescope and Rubin Observatory. I am a graduated DSFP fellow and have been trained to work on large datasets and analyze them using statistics, machine learning, data visualization, software engineering, time-domain analysis, and image processing. I am also an active member of the LSST Transients/Variables Science Collaboration working on proposing observing strategies for the Rubin Observatory. Additionally, I am a member of the KELT science team and have taken part in sorting and vetting of transiting exoplanets. Here is the list of my publications:
