DESCRIPTION:Research:\n\nI am committed to a career on foraminiferal resea
 rch and their use as indicators of ancient and modern marine environments.
  My research involves multidisciplinary investigations of recent and fossi
 l foraminifera that include fieldwork (both land and sea)\, traditional an
 d molecular taxonomy\, phylogeny\, stratigraphy\, faunal analysis\, sedime
 ntology\, and stable isotopes geochemistry.\n \nOne important part of my r
 esearch is focused on understanding the distribution of Late Cretaceous fo
 raminiferal habitats\, documenting their response to global climatic chang
 es\, and characterizing their taxonomy\, phylogeny and the ecological stra
 tegies of individual species. I have characterized foraminiferal assemblag
 es from many Late Cretaceous localities\, established a detailed depth ran
 king of species based on stable isotope analyses and demonstrated the impo
 rtance of high-resolution studies in tracing paleoceanographic changes.\nI
  am now also engaged on applying insights on fossil foraminifera and envir
 onments to the study of modern oceanic ecosystems. One of my recent studie
 s is aimed to document the response of benthic communities to possible fut
 ure climate warming by monitoring the effect of local warming on the benth
 ic foraminiferal population living in the shallow coastal Mediterranean en
 vironments. Another recently completed study involved ecological monitorin
 g of the benthic foraminifera response upon removal of aquaculture fishcag
 es in the Gulf of Aqaba-Elat.\nI have also recently established molecular 
 genetic tools in my laboratory to be able to explore fundamental ecologica
 l and oceanographic problems that concern the impact of environmental pert
 urbations on the marine ecosystem.  Our main focus at this point is to doc
 ument the large-scale invasion of alien tropical species\, into the Easter
 n Mediterranean by comparing the genetic diversity and morphological and e
 cological characteristics of selected foraminifera from the Israeli Medite
 rranean coast and the Red Sea.
