Mom pointed out that MD wasn't in the nomenclature.

 \subsection{History of simulations}
 
-Early molecular dynamics (MD) work on receptor-ligand breakage by Grubmuller 1996 and Izrailev 1997 (according to Evans 1997).
-\citet{evans97} introduce a smart Monte Carlo (SMC) Kramers' simulation.
+There is a long history of protein unfolding and unbinding
+simulations.  Early work by \citet{grubmuller96} and
+\citet{izrailev97} focused on molecular dynamics (MD) simulations of
+receptor-ligand breakage.  Around the same time, \citet{evans97}
+introduced a Monte Carlo Kramers' simulation in the context of
+receptor-ligand breakage.  The approach pioneered by \citet{evans97}
+was used as the basis for analysis of the initial protein unfolding
+experiments\citep{rief97a}.  However, none of these earlier
+implementations were open source, which made it difficult to reuse or
+validate their results.
