With respect to issues of representation, Archangeli has proposed
underspecification: individual sounds have the minimal number of features
possible in their most basic representation.

In joint work with Doug Pulleyblank of University of British Columbia,
Archangeli has developed a parametric model for expressing relations between
representations, a model which makes clear predictions made about possible
and impossible relations.

Underspecification and parametric rules are fairly simple, straightforward
formal models. Despite their formal restrictiveness, neither takes into
account the physical side of phonology, nor the fact that the formal logical
possibilities vastly exceed the attested combinations found in natural
languages. In response, Archangeli (jointly with Pulleyblank) has developed
a model of feature co-occurrence constraints. This model restricts conditions
on relations and representations to those which reflect physical properties
of the articulatory and acoustic system.

Archangeli's most recent work in this area is exploring the sets
of rules which may or may not co-occur within a language. Her work in this
area takes an optimization approach to integrating the formal parameters
of the rule sets with their physically rounded conditions.

Archangeli's research also includes (I) study of prosodic templates;
(ii) fieldwork in Indonesia on the phonology of Sasak and Bugis; (iii)
exploration of the syntactic behavior of Sasak clitics (jointly with Dr.
Husni Muadz, Universitas Mataram).
