To all subscribers of ISOGEOCHEM,

as I recently subscribed to ISOGEOCHEM I want to introduce myself first.
My name and current address is listed in the signature at the end of this 
message.
I did my MSc. and Ph.D. with Jan Veizer at the Department of Geology, 
Ruhr University Bochum (Germany).
Currently I am working as a postdoc with John M. Hayes at the 
Biogeochemical Labs, Indiana University, Bloomington (USA).
My former work concentrated on the following topics (thesis titles):
"Geochemistry and isotopes of the river Rhine tributaries: The Wupper. 
Natural and anthropogenic impact as related to seasonal variations" (MSc.),
"Modeling high-resolution isotope stratigraphy (d13C,me/Aptian) d18O, 
87Sr/86Sr) of the Jurassic and the Lower Cretaceous 
(Bajocian-Barremian/Aptian)" (Ph.D.)
My current project is sponsored by the German Science Foundation (DFG) as 
a research fellowship entitled "High resolution GC/C/MS (GC-IRMA)
analyses of boreal Cretaceous black shales (Aptian, Fishshale), 
northern Germany."
My research interests are:
	Sedimentation and related low-temperature geochemistry
	Sedimentology and geochemistry of carbonate, evaporite and 
'black-shale' rocks and fossils (incl. inorg./organic carbon, oxygen, 
sulfur and Sr isotopes); diagenetic histories of the rocks and fossils; 
biogeochemistry of calcareous shells and organic material; isotopic 
evolution of seawater (incl. isotope stratigraphy).
	Behaviour of elements and isotopes in surficial environments; 
their surficial geochemical cycles; environmental 
implications; geochemistry of waters; ecology of rivers and lakes.
	Mathematical modeling of geological and geomorphological 
problems; application of nonlinear mathematics and statistics; applied 
computer science.
	Modelling geochemical cycles in the lowermost atmosphere; short 
term (daily) and long term (seasonal) fluctuations of oxygen and ozon 
near the surface; anthropogenic production and natural decomposition of 
ozon near the surface (individual transportation / industrial emissions).
	Modelling subrecent climates by the help of treerings & other 
proxies; Time Series Analyzes (TSA) of multisignal measures: (a) 
classical methods [e.g. Fourier Spectra / ARMA Models] and (b) other 
methods [e.g. applied chaos theory].

As a (more) detailed description I placed an extraction of my CV on my 
WWW homepage. The address is listed in my signature.

Regards,
Olaf
