Yes, but you have to add Department to STARTD_ATTRS in the config
file in order to get it considered by the negotiator in calculating
the rank.  Also you have to allow for the fact that DEPARTMENT
might not always be defined.

RANK=(ifThenElse(isUndefined(Target.Department),0,ifThenElse(Target.Department=="Chemistry",1000,0)

Be aware that doing it with the RANK statement can result in
jobs of other non-chemistry departments being pre-empted to make
room for yours.  You could also define an 
+AccountingGroup=chemistry.myusername
and then define GROUP_QUOTA_chemistry=nnn and/or 
GROUP_PRIO_FACTOR_chemistry=nnn
