2001–2015 Institute for Pure and Applied
Mathematics (IPAM) at UCLA
On August 21, 2015 I concluded my fifteenth and final summer as director
of the RIPS program at IPAM, a
National Science Foundation's institute located at UCLA.
–Program director for Research in Industrial Projects for Students (RIPS)
I worked with IPAM
staff and the late Robert Borrelli of Harvey Mudd College to
create the RIPS program in 2001, and then to continue developing the
program over the fifteen summers of my directorship.
I enjoyed working with the many students and academic mentors who
participated in RIPS over all those years.
My approach to
managing the RIPS program,
was presented to the panel Starting
and maintaining a student industrial research progam in
the mathematical sciences at the MAA's MathFest of Aug 4, 2007 in San Jose, CA.
RIPS continued in the summer of 2016 under the directorship of the
talented Spanish mathematician and teacher Prof. Susana Serna of the
Autonomous University of Barcelona.
Prof. Serna had been an academic mentor for RIPS teams for the previous

A miscellany to include lecture notes, drafts and reminiscence
Some activites in mathematics
2011 I participated in review panels for the NSF and for
the S. -T. Yau High School Mathematics Awards.
2007–present, Instructor at the
LACES Calculus Camp (four days in April), the creation of Robert
Vriesman, Chairman of the Math Department at the LACES magnet school in
