Where I live & work now: Gorgeous Bavaria in the South of Germany!!!




Where I used to work: the American Museum of Natural History

Tyrannosaurus rex
T-Rex attack!


Where I used to live: Manhattan


Lower Manhattan with the "tribute in light", seen from Brooklyn. For my first year in New York, I lived a few blocks south of Ground Zero, i.e. near the rays of blue light you see in the photo.

The remaining years I lived near the Empire State Building.
The colors of the lights on the ESB are different
every day. I thought this combination was
particularly pretty, especially with the way the
sky looked that very moment.

I was extremely lucky to find a house that has a garden in the back for the use of all tenants, especially right in the middle of Midtown Manhattan, where thousands of commuters pass through every day. This is where I sometimes had breakfast and dinner in the summer.


Collecting in Costa Rica and Panama
Canopy tower on Barro Colorado Island

In Corcovado National Park

In Rara Avis



Collecting in California
A nice spot that yielded Rhadinocerea and even Orussus



A beautiful river valley near Lake Tahoe
The malaise trap in that valley was very successful.



Collecting in Maryland, USA
That's me catching Macroxyela.
It's quite a stretch.

Collecting in Germany
Obviously, collecting Monoctenus
is much easier. By the way, this was
one of only three days of nice, warm
weather I had in three weeks in Germany.
I enlisted my mother as a parataxonomist.
She managed to collect some Monoctenus
without a net.
