Biography and Research Information
OverviewAI-generated summary
Frederick W. Spiegel's research focuses on the study of protostelids and other amoeboid organisms, investigating their evolutionary relationships and biodiversity. His work has contributed to the taxonomic validation of genera, such as *Pocheina*, and the phylogenetic placement of specific species, like *Microglomus paxillus*. Spiegel has also explored the biological functions of contractile vacuoles within eukaryotic cells.
His recent publications include a guide to identifying protostelids and discussions on the evolution and diversification of unikonts, with an emphasis on fungal-like forms. He leads a research group at the University of Arkansas at Fayetteville and has collaborated with other faculty members, including Jeffrey D. Silberman and Kevin Regis, on shared publications.
Spiegel's scholarship is marked by a h-index of 21, with over 6,600 citations across 52 publications. His research activities are ongoing, as indicated by recent publications in 2023 and 2024.
