I write to resign my faculty positions in the Department of
Physics and the Department of Electrical Engineering and Computer 
Science effective June 30, 2002.  In addition, I request an 
unpaid administrative leave of absence beginning on April 8, 2000 
(corresponding to the first paid "work" day of the first semimonthly 
pay period in April) and extending through the effective date of 
my resignation.  (I propose that I will draw no salary from the 
University's central "Education and General" budget following
a final, full paycheck at the end of March 2000.)  During 
the administrative leave that I request, I will fulfill my 
teaching responsibilities at SU through the completion of the 
current semester.

The timing of my resignation and the leave that I request are 
intended to be responsive to the needs of SU students and sponsors
during my transition to a faculty position at Florida State University.
In particular, I would like to continue to serve as the advisor 
for several Ph.D. students who wish to complete their degrees from
SU under my direction.  In addition, I propose to continue serve as 
Principal  Investigator on several of my external grants and contracts,
which  will remain at Syracuse through their current
expiration dates (May through September 2000).  I am also willing 
to continue to set "computational science exams" for the Ph.D.
program in computer and information science, if this is of interest 
to the Department of Electrical Engineering and Computer Science.
In recognition of my continuing relationship and responsibilities 
at SU, I request that I retain my current office in the Center for 
Science and Technology through July 31, 2000.

I thank you for the opportunities given to me at Syracuse.
I look forward to continuing interactions with several Syracuse
colleagues and friends in the years ahead.
