His research interests and that of his students have focussed
on various aspects of the biology of the algae with an emphasis on seaweeds. Many of the seaweeds
that have been investigated are utilized by humans as well as being
intrinsically interesting organisms. These include certain red seaweeds
(especially Mazzaella [formerly Iridaea] and Chondracanthus (formerly Gigartina) that produce carrageenans
(note that much carrageenan now comes from aquacultured Eucheuma
and Kappaphycus, mostly from the Philippines), polymers that find many uses
for their gelling and viscosity regulating properties. More recently the biology
and systematics of several species of Porphyra was investigated. The edible product "nori" is made from certain species of Porphyra, and there are nearly two dozen
species of this seaweed in the
Recent and current studies have included the biology of eelgrass (a kind of seagrass) meadows (Nelson & Waaland 1997), the systematics and phylogeny of certain seaweeds (e.g., the Bangiaceae [Stiller & Waaland 1996, 1993] and Ceramicaceae (Carlile, Cho & Waaland 2010) in the red algae, and the Ulvaceae in the green algae (Hayden & Waaland 2004, Hayden et al. 20##).
