  The proposed high luminosity high energy Electron-Ion Collider (EIC) will
explore the proton/nuclear structure in a wide Bjorken-x ($x_{BJ}$) and $Q^{2}$
phase space. Heavy flavor products are generated in initial collisions and have
their hadronization influenced by the nuclear medium. Heavy flavor hadron and
jet measurements at the future EIC will allow us to better constrain the nPDFs
especially in the poorly constrained high $x_{BJ}$ region, precisely determine
the quark/gluon fragmentation processes and directly study the quark/gluon
energy loss within the nuclear medium. These measurements can constrain the
cold nuclear medium effects for previous and ongoing heavy ion measurements at
the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC).
Silicon vertex/tracking detectors are essential to realize the heavy flavor and
jet measurements at the EIC. Feasibility studies in simulation for proposed
heavy flavor and jet observable with evaluated detector performance at the
future EIC will be discussed.
