Following in Prof. Walker's footsteps, David Jovel wins the GEM Fellowship! GEM is a prestigious fellowship aimed at supporting underrepresented groups in STEM through their graduate program. One of David's personal objectives is mentor and empower underrepresented youth in STEM. David's focus is on the loss of performance efficiency due to heat generation in Hall Effect thrusters.
