<b><u>Abstract:</u></b> To portray the internal structure of hadrons, the understanding of the intrinsic properties of their building blocks i.e. quarks and gluons is indispensable. We present the study of spatial distribution of quark flavors of hadrons via
both chiral-even and chiral odd sector of generalized parton distributions (GPDs), emphasizing the difference arising from different quark flavors of hadrons. This structural anatomization is carried out by making the use of light-front dynamics. Distributions
in the forward limit and lowest moment of GPDs will also be discussed with their comparison to other available model predictions and lattice data. Additionally, we explore how quark dynamics alters in the presence of isospin asymmetric nuclear matter. </div>

<b><u>Abstract:</u></b> We discuss in detail the relativistic spatial distribution of transverse angular momentum, including both orbital and intrinsic spin contributions. Using the quantum phase-space formalism, we begin with the definition of the three-dimensional
spatial distributions of transverse orbital angular momentum and intrinsic spin in a generic Lorentz frame. By integrating these three-dimensional spatial distributions over the longitudinal axis, we derive for the first time the relativistic spatial distributions
of transverse orbital angular momentum, intrinsic spin, and total angular momentum for spin-0 and spin-1/2 targets in the transverse plane. We verify the transverse spin sum rule for spin-0 and spin-1/2 systems and find that the transverse total angular momentum
distribution is non-trivial, even for spin-0 targets. We also show how the distributions of transverse orbital angular momentum, intrinsic spin, and total angular momentum change with the target momentum.</div>
