             abstract = "We present a study of the impact of photoionization feedback from 
                         young massive stars on the turbulent statistics of star-forming 
                         molecular clouds. This feedback is expected to alter the density 
                         structure of molecular clouds and affect future star formation. 
                         Using the AMUN-Rad code, we first generate a converged isothermal 
                         forced turbulent density structure inside a periodic box. We then 
                         insert an ionizing source in this box and inject photoionization 
                         energy using a two-temperature pseudo-isothermal equation of 
                         state. We study the impact of sources at different locations in 
                         the box and of different source luminosities. We find that 
                         photoionization has a minor impact on the 2D and 3D statistics of 
                         turbulence when turbulence continues to be driven in the presence 
                         of a photoionizing source. Photoionization is only able to disrupt 
                         the cloud if the turbulence is allowed to decay. In the former 
                         scenario, the presence of an H II region inside our model cloud 
                         does not lead to a significant impact on observable quantities, 
                         independent of the source parameters.",
