Jennifer (Jen) Li is a long term member of Spacesim. She is mostly associated with the group referred to as F4. Most of her contribution to Spacesim is in the realm of planetariums, though during the initial years of her association with the club, she also participated in many work session activities as well as PR efforts. Of the OCESS members graduated from high school in 2008, Jen is the earliest to have joined the club.
For the 2007-08 school year, she, in theory, served as the Planetarium Commander. However, due to her decreased participation in the club, incompatible personality with Education Commander Jeff Gao, and the assertive efforts by future Planetarium Commander Bryce Storey to fill the role, her real role as commander was ambiguous.
