to publish their work in journals of their respective fields
of research. We are truly blessed to have such talent in the
department for mentoring our students.
One big item on the department’s horizon is next summer’s
move to Patterson Hall. This past summer, the building
underwent a substantive renovation which included air
conditioning and an elevator for the building. In preparation
for the move, I downsized a lot of things in the department that
needed to be shredded, recycled or thrown away. Since this
has been our home for quite some time, you can imagine all
that has accumulated over the years – such as old grade books
from the 1920s and 1930s. Do not worry, I did not look up any of
your grades, but it was a bit nostalgic given the department’s
many years of solid educational history. Once again, we thank
you for your support of USD and our department. As always,
please stop in if you are ever in the area.

Greetings Alumni and Friends,
It is time once again to provide you
all with an update of our past year.
The department is making great
progress in its commitment to
educating our students with a solid
background that will provide them
success in their future endeavors.
One indicator of this claim’s fulfilment
is embodied by our two students who recently passed the
first actuary exam—an achievement of great value as they
seek summer internships that could then become full-time
careers. Also, two of our graduate students wrote a thesis
for their master’s degrees, and some of our undergraduates
have undertaken summer internships and research projects
with faculty. Along with these accomplishments, our faculty
offers rigorous courses that the students appreciate as
reported by the latest National Survey of Student Engagement
We were recently informed that Dr. Yuhlong Lio received the
President’s Award for Research Excellence in the Established
Faculty category. All of our faculty work hard and continue
From the Chair’s Corner
Joint Mathematics Meetings 2015
Mathematics graduate students
received student travel grants to participate in the
2015 Joint Mathematics Meetings in San Antonio, Texas, from
Cao presented a research paper, “A Dynamic System based on
Weibull Distribution,” co-authored with Dr. Yuhlong Lio, Dr. Nan
Jiang and Dr. T.R. Tsai.
Brown’s paper, “Maximum Likelihood Estimation for the
Generalized Exponential Distribution Parameter under
Progressive Type-II Censoring,” was co-authored with
Dr. Yuhlong Lio and Dr. Nan Jiang.
Dr. Lio accompanied the students to the conference.
Mathematical Association of America–
North Central Section Math Competition
Matthew Buhr, Corina Larson
represented USD in the annual Mathematical Association
of America (MAA)-North Central Section Mathematics
Competition held on Nov. 15, 2014. Ninety teams from
colleges in Minnesota, North and South Dakota and Manitoba,
Canada, participated. The USD team placed in the top one-
third pool, a performance which is considered commendable
and is acknowledged by the MAA on their website. Coached
by Catalin Georgescu and Gabriel Picioroaga, the students
prepared for about two months for the three-hour test.
