Chair, Division of Science and Mathematics , 2011-present

As a Division Chair, my duties and responsibilities include those specified in the UMN Morris’s Constitution Article III Section 2. The following is a partial list of specific activities and outreach that I have done in support of my required responsibilities.

1. I have strongly encouraged faculty to develop new curricular in their areas or in support of UMN Morris’s General Education Requirements. For instance, we (in Science and Math) have developed and taught at least ten new IC courses and at least twenty new electives. We have also proposed a new academic minor program in Data Science which was approved by the UM Board of Regents.
2. I have worked with UMN Morris’s Alumni Relations Office and Fund Development Office on several partnerships since I began as a Division Chair and I have continued to do so. Since the Science and Math Faculty and Students rely on support from the Science and Math Alumni Foundation Funds, I took the initiative to reach out to these two offices and I have been continuously committed to doing “friend raising.” One of my goals has always been to make sure that the Science and Math’s Quasi Endowment Fund has a healthy capital to generate enough return on investment to sustain the additional annual resource requirement to support faculty and students’ learning and research experiences. For instance, I host the annual Science and Math Alumni and Students Networking Event over lunch time on the day before UMN Morris’s Homecoming. (I had to do this virtually in 2020 due to the pandemic.) I have travelled with our colleagues in Fund Development to Seattle and Bellingham in Washington State to host events for UMN Morris’s Alumni and Friends.
3. I have worked with offices across UMN Morris campus including Admissions, Office of Academic Success, Academic Center for Enrichment, etc.. For instance, every semester, pre-pandemic, I hosted a comprehensive Science and Math Tour in conjunction with an Admissions all-day campus event for prospective students who are interested in academic programs in the natural, physical, or mathematical sciences. I worked with the Advising Office and the Office of Academic Success on faculty-advisee issues and other academic retention initiatives. By and large, all requests for faculty participation from the aforementioned offices would go through me.
4. I served as Chair of the systemwide Senate Committee on Faculty Affairs (SCFA); and I led the subcommittee’s work to improve our Faculty Development Leave Policy as well as other faculty related policies. My six years on SCFA is beneficial in my role as a DC because I am very aware of university policies that are related to faculty. SCFA’s portfolio also includes human resources’ policies, faculty tenure/promotion, and faculty compliance policies; and my up-to-date knowledge on these policies is handy when I conduct faculty searches, review faculty (promotion/tenure/annual), or maintain standards of faculty’s teaching, research/scholarship, or outreach activities.
5. I work closely with the Office of the Provost of the University of Minnesota because the provost oversess issues related to tenure and promotion for all regular faculty.
6. Campus wide, I served on Curriculum Committee, the FREF Review Committee, and all other review committees that the DC has to be on. Due to my participation on systemwide senate committees, I also have served on UMN Morris’s Faculty and PnA Affairs Committee, UMN Morris’s Scholastic Committee, and systemwide Faculty Consultative Committee.
7. For some reason, I was often asked to lead search committees or to be on them. I think I have represented the UMN Morris very well by chairing the search committee for the UMN Morris’s Chancellor (twice) and for being on the University of Minnesota’s Presidential Search Advisory Committee.
8. I have done and will continue to do the following as part of my commitment to recruiting faculty and staff from diverse and underrepresented groups. I have represented our campus at the Southern Regional Educational Board's Conference on Teaching and Mentoring future faculty from underrepresented groups for four years, twice in Atlanta, once in Arlington, Virginia, and sadly, once in pandemic style, virtual. One of the goals of this endeavor is to connect with Ph.D. faculty, staff, and students from underrepresented groups so that they are aware of our campus and of possible faculty or staff opportunities as well.
9. In a typical year,
   • I approved an average of 750+ requisitions and additional 200+ of other types U of M Enterprise Financial Systems (efs) expenses, and managed the Science and Math Foundation funds and the allocations of all Science and Math Operations and Management funds. It is my fiduciary responsibility to make sure that I balance all our budgets at the end of every fiscal year.
   • Conducted only thirty three spring annual reviews of regular faculty, and 2.75, now 2.25, staff reviews.
   • Conducted P & T process for an average of two faculty, and fall annual reviews of an average of six additional faculty.
   • Led the financial discussions on short term renovation plans for the some teaching and research classrooms/labs/spaces.
   • I would resolve multiple student-related or student-faculty-related issues.

Assistant Academic Dean (Semester Conversion), University of Minnesota- Morris, 1998-2001.

As one of the assistant academic deans, my administrative responsibilities included the following:

1. Led the campus through the semester conversion from the quarter system.
2. Supervised three campus administrators, namely, Director of the Academic Advising Office, the Registrar, and the Director of Computing Services and Information Technology.
3. Collaborated with the UM-TC and systemwide administrators to make sure the transition process is smooth and the policies are updated.
4. During and after the first year of the semester system, I led discussions on adapting changes to the academic calendars including the addition of a Fall Break.
