  We present time-resolved measurements of electron transport through a quantum
dot. The measurements were performed using a nearby quantum point contact as a
charge detector. The rates for tunneling through the two barriers connecting
the dot to source and drain contacts could be determined individually. In the
high bias regime, the method was used to probe excited states of the dot.
Furthermore, we have detected bunching of electrons, leading to
super-Poissonian noise. We have used the framework of the full counting
statistics (FCS) to model the experimental data. The existence of
super-Poissonian noise suggests a long relaxation time for the involved excited
state, which could be related to the spin relaxation time.
