I am a researcher in Prof. Rich Wolski's MAYHEM (Middleware and Applications Yielding Heterogeneous Environments for Metacomputing) group at the Computer Science department of the effulgent UC Santa Barbara.

Previously, I had the privilege of working at the Universitetet i Tromsø of Norway in Prof. Dag Johansen's mettlesome WAIF (Wide-Area Information Filtering) research group.

And before that, I happened to have completed Ph.D. studies at UC San Diego under the perspicacious guidance of Prof. Keith Marzullo.
