Jet Physics and Event Shape Studies at HERA
  A review is given of the latest results on jet production and studies of event shape variables in deep inelastic scattering at HERA. Jet cross sections studies for inclusive jet and dijet events are presented and compared to next-to-leading order QCD calculations. Extraction of the strong coupling constant alpha_s is discussed.
