DESCRIPTION:Despite the simplicity of their microscopic consti
 tuents\, electrons and nuclei\, the theoretical mo
 deling of condensed matter systems is very difficu
 lt. The origin of the problem is that a very large
  number of particles are interacting with each oth
 er. In my talk\, I will discuss\nvarious theoretic
 al approaches to deal with interacting many-partic
 le systems. In the first part\, I will introduce a
  new method to describe molecular liquids\, such a
 s water\, which plays an important role in\nbiophy
 sics and electrochemistry.  In the second part\, I
  will describe recent theories of electronic excit
 ations in materials. Specifically\, I will show ho
 w an accurate description of the interaction betwe
 en electrons and\nplasmons\, quantized charge dens
 ity oscillations\, can explain recent photoemissio
 n experiments in doped graphene and silicon.
