Honors and Awards
Received
2013
Freeman
Hrabowski Innovation Grants Award for Founding “The Math Gym”.
The Math Gym (MG) is a place in the
campus where all the tools needed to stay in excellent math shape are available
to students. Students are referred to MG
when their performance in various diagnostic tests or in the proprietary
QuizZero, conducted by the Department of Mathematics and Statistics, indicates
that they may need to boost certain parts of their basic math skills. TMG is
also the place to review and reinforce the pre-requisite materials for students
who are currently in any course on campus in which students routinely use math
skills. Students can choose to go to the TMG on their own or because a faculty
member recommends it to them. MG is the place for students to go to get a quick
brush up of the specific skills they need at that time, and get back to work.
The Math Gym also provides personal trainers (PT) who will work with students,
one-on-one, keep up a strict customized daily regimen, developed in
consultation with knowledgeable math coaches, to improve and maintain basic
math skills. This just-in-time teaching coupled with mastery based learning
methods is the key feature of MG.” (MathGym.umbc.edu)
2013
University
System of Maryland Board of Regents’ Award for Innovative Excellence
“Nagaraj K. Neerchal has been a member of
the Mathematics and Statistics Faculty since 1986, and is known as an exemplary
researcher in the field of applied statistics. Since becoming chair of the
Department of Mathematics and Statistics in 2006, he has developed a reputation
as a pioneer for educational and administrative initiatives…….
………Neerchal is also a co-founder for the
Center of Interdisciplinary Research and Consulting (CIRC), which has been a
major contributor to active learning at UMBC. It combines the training of
graduate students with professional consulting, and has become the host of a
National Science Foundation (NSF) funded Research Experience for Undergraduates
(REU).” Quote from http://www.umbc.edu/newsevents/Awards2013/index.html
2010
Kauffman
Entrepreneurship Faculty Fellow for the College of Natural and Mathematical
Sciences, Alex Brown Center for Entrepreneurship, UMBC
“UMBC’s Alex Brown Center for Entrepreneurship encourages
that kind of thinking. The center received a gift from the Kauffman Foundation
to infuse entrepreneurship throughout UMBC’s curriculum. Three faculty fellows,
one from each college, lead the way. They serve as idea keepers, champions and
mentors to the campus community.” Quote from http://www.umbc.edu/innovate/
2011
Fellow,
American Statistical Association
“For research and service contributions
to the profession, with particular emphasis on applications of statistical
methods for interdisciplinary research; and for educating and mentoring
graduate and undergraduate students.”
2008
Received Service Recognition Award from the American Statistical Association’s
Maryland Chapter.
“In appreciation for the many years of
dedicated support to the ASA Maryland Chapter;
for serving several terms in Chapter offices; and especially for promoting
statistics on a regional level.”
2001

Graduate
Program Director for the Department of Mathematics and Statistics, UMBC, 1996—1999
- Implemented new ideas into the MS program
in Statistics. Introducing a track in Environmental Statistics. A proposal for
a track in Biostatistics is under consideration by the Graduate Council.
- Conducted weekly graduate student seminars to inculcate presentation skills. Brought
Toastmasters'' structure to the graduate student seminar. (A student is designated as a chair for a
session with two speakers and two evaluators. The Evaluators give concrete
feedback on presentation aspects of the speakers immediately following the
speech.) Faculty members are recruited as evaluators and this increased faculty
participation. Took the necessary steps to make the seminar mandatory for all
supported students. Seminar series has
been cited by many colleagues as ``the highlight'' among departmental
activities.
- Used my contacts at MathSoft, and
- Conducted annual departmental orientation
for the new graduate students. As a new feature incorporated a
workshop on teaching into the orientation program with invited speakers from Learning Resources Center.
- Pushed for a campus‑wide orientation
for all incoming graduate students. Participated in the planning of the first campus‑wide orientation of all
new graduate students.
- Arranged campus interviews for all local applicants for our graduate
program. This new approach has
proved to be a very effective. We have four local students admitted with
support this year.
- Worked with the Undergraduate Council of
Majors and Pi‑Mu‑Epsilon (the undergraduate honor society) to publicize the Combined BS/MS program
offered by the department.
- Increased
the recruiting efforts within the
- Organized bi‑weekly Software Study'' group meetings where Students and
interested faculty meet regularly and teach each other new developments in
statistical software. Meetings help to increase
the overall level of software knowledge
among students and to foster a community
spirit in the department.
- Re‑designed and updated the Gradate Program Web Page of the
department. Regularly contributed pictures of graduations,
departmental activities, and social functions to the web page.
·
Designed
courses in Applied Statistics, which emphasize data analysis using statistical
software such as SAS, SPLUS and R.
