OK OK - so most of this way out of date and my picture is a few years old
but I plan to update this all real soon now - REALLY!!! At least
here are some
pictures
from our August 2001 trip to Australia.
What I do
I am a principal computer scientist in the
biomed group
(our picture)
of the
Pittsburgh Supercomputer Center (PSC)
where I work mostly in medical image processing, visualization of
GByte to Multi-TByte
volumetric datasets and pattern classification from image and mass
spectral proteomics data.
My
Carnegie Mellon University
office is in the
Mellon Institute
building on the block
adjacent to
Heinz Chapel
and the
Cathedral of Learning. .
During the past several years I have been the principal investigator and
technical lead of
our group's
projects to deliver and visualize massive anatomical datasets including the
visible human,
the
4D visible mouse,
and now
C. elegans electron microscopy reconstructions
in collaboration with
David Hall and his team
in
The Center for C. elegans Anatomy
at the
Albert Einstein College of Medical
and
Richard Fetter
in
Cori Bargmann's
lab at
The Rockefeller University.
My first projects at PSC were in collaboration with Drs
Michael Becich
and
John Gilbertson
in the
Department of Pathology
at the
University of Pittsburgh Medical Center
to store, process and disseminate a database of pathology images and
use the data for
automated pathology diagnosis.
My particular part of that work was centered on the analysis of
microscopic prostate cancer images and techniques for comparison and
retrieval of images based on signature measures.
During the summer of 1995 I completed a test of my homegrown OCR system, Aurora, on
an interesting and relatively rare 956 page book of historical interest
- the 1849 Transactions of the American Medical Association.
(It was not a good idea to get sick in 1849!)
Processing of this text proved to be impossible with available
commercial OCR products that were tried.
See this page
from the University of Pittsburgh Libraries for a bit more
information about that project.
Aurora has been in development on an "hour here an hour there" basis
since 1988.
Previously I had worked on the image storage, display and delivery
components of Project Mercury,
an electronic library project at
Carnegie Mellon.
My main contribution was
"the world's fastest" FAX Group 4 decoder and viewer.
The home Front
Rose and I are usually jumping to keep up with all the
activities Nat and Annamarie get into.
Here's a vacation picture with (part of) Rose's
side of the family and one of Annamarie and Nat with their
cousin Jordan in the middle from 1995.
Much more recently ...
Nat attended
"Operation Catabupt" at Rose-Hulman during the summer of 2002.
Now Nat is entering his sophmore year at Pitt studying computer engineering
but also working with his Dad doing computer image processing for our
SuperWorm project. Annamarie is a senior at Franklin Regional HS and
was a featured dancer in the last three year's spring plays including
this year's presentation of
Once Upon a Mattress.
Here's the
Post Gazette review.
Teaching
I usually teach one course per term as an adjuct faculty member in the
Department of Information Science & Telecommunications
in the
School of and Information Sciences
at the
University of Pittsburgh.
My specialties are "techie" courses such as computer science
concepts, compiler construction, information theory,
operating systems, computer graphics, image processing and the like.
Recently I've been teaching
IS2610, Data Structures,
more often than any of the others.
Last term Stu Pomerantz and I co-taught CS1566, Computer Graphics,
for the
Pitt Computer Science department.
