Summary of Research

My first research project was in Dr. Thomas's Applied Optics Laboratory at NJIT, where we conducted experiments on nano drones using a laser system and eventually created a numerical simulation of nano drone rotors, for the characterization and weight estimation of the nano drones from raw optical data. We also created a numerical simulation of an entomological photonic sensor coupled with a mosquito population for population density retrieval.

I also worked in Dr. Dibakar Datta's Molecular Dynamics (MD) Simulation Group at NJIT, to study the interatomic friction between four different 2D material bilayers, including the well-known material graphene, as well as the effects of hydrogenation on nanoscale friction. We also investigated the effects of imperfections/dents on nanoscale friction in molybdenum disulfide by simulating an atomic force microscope (AFM) tip experiment. I received the 2020 Goldwater Scholarship for this work.

Starting my junior year at NJIT, I joined Dr. Kuzichev's Space Plasma Modeling Group at NJIT. We conducted a linear stability analysis of electron velocity distribution functions observed by the Wind Spacecraft, and modeled whistler wave-particle interactions of particles along magnetic field lines of the Earth.

During the summer of 2021, I interned virtually for Dr. Brunner's Ba-Tagging Group and the nEXO Collaboration at McGill University, through a Fulbright Canada Mitacs Globalink Internship, where I analyzed images of laser-ablated ion plumes using ImageJ software to characterize its features.

I am now part of Dr. Constantinou's Lattice QCD (LQCD) Group at Temple University, where we study the 3D tomography of the proton from LQCD. Such information is obtained through the generalized distribution functions (GPDs), complemented by the transverse-momentum dependent distributions; both are limitedly studied. We aim to advance knowledge on GPDs using numerical simulations of QCD, based on a novel approach to fully determine GPDs in the 3D parameter space.
