A brief curriculum vita is available for download in PDF format.

I came to Kent State University in 1997, after I received my Ph.D. at the University of Utah, under the direction of Joseph L. Taylor. In my dissertation and early post-doctoral research, I used various tools from functional analysis to study geometric representations of Lie group representations. Other early research interests at KSU involved applications of functional analysis to perturbation theory and approximation theory. My current research interests are applications of functional analysis to numerical methods in linear algebra.
I've always enjoyed teaching very much and I particularly appreciate student participation in class and/or office hours. In addition to teaching and publishing math research, I served for many years as a Faculty Associate for the First Year Experience program, which is run by KSU Residential Living.. I also serve as the departmental community outreach coordinator, specializing in high school recruitment and freshman retention.

This semester I am teaching Trigonometry (Math 11022-003) and Calculus I (Math 12002-005). The Trigonometry class meets Tuesdays and Thursdays from 9:15- 10:30 AM in MSB Room 102. The Calculus class meets daily from 12:05 - 12:55 PM in MSB Room 121. In general, this semester I will be on campus in the mornings. Every weekday, I will be in or around my office from 11:00 AM - 12:00 PM. Then I teach calculus for an hour. Afterwards, I will generally be available as need. On Tuesdays and Thursdays I will be in or around my office from 8:45 AM to 9:15 AM. I then teach Trig until 10:30 AM and will back in my office until my calculus starts at noon. Generally, if nobody has contacted me asking to meet with me, I leave sometime after 1 PM. But I am often free to stay until much later. So, if you would like to meet with me just let me know before or after class or by email at lsmithie@kent.edu. My office is in the Mathematical Sciences Building (MSB 204, 2-9027).

    My research interest is the study of (linear) operators and operator-valued functions. My current research project is a study of Gershgorin-type sets with Richard S. Varga. This project evolved into a study of nearly normal matrices. Prior to this, I did a project, with Natacha Fontes, which combined the tools of operator theory and approximation theory. Before that, I worked with Jan Kover and Per Enflo on projects involving applications of operator theory to perturbation theory.

    Community Outreach

    from the Homepage of Laura Smithies

    I am the Outreach Coordinator for the KSU department of Mathematical Sciences. I serve as a liaison between our department and the community. I am especially interested in matters pertaining to KSU freshmen and high school students. I routinely represent our department at events directed at these groups. For example, Academic Discovery Days, College of Arts and Sciences, and KSU Residential Living Events.
    I also organize our department's annual High School Math Scholarship Contest. Awards range from $100 book scholarships to $4,000 in tuition waivers for KSU. Please contact me, if you have any questions about these or similar programs.
    Over the years, I've set up volunteer tutoring programs at local schools such as Rauch Intermediate and Brown Elementary. Many of these volunteer tutors are members of the KSU organization "Frasority". I am the faculty adviser for this service club which was formed by First Year Experience students.
    Last year, I started a Bunny Outreach program. The special education students at Roosevelt High School are growing herbs for my bunnies at a local community garden. I bring my bunnies into their class, and to the garden and teach them about bunny care and feeding. This year I will give several talks to a local math club for gifted students (at Stanton). Please contact me, if you would like me to work with your gifted (or struggling) math students.
    For the last five years, I have been a coach or assistant coach in basketball and soccer in the All Star Training Club. This is an athletic organization for mentally or physically challenged people. I am also a trainer for Special Olympics athletes in soccer and track.
