Lindsey Possehl

A 2015 graduate, Lindsey Possehl double majored in Mathematics and Computer Science, which led to her current role as a data scientist for Ruffalo Noel Levitz. 

For Lindsey Possehl, being a Mountaineer runs in the family.

With both her grandfather and father (and, later, her younger brother) as Western alumni, Lindsey always suspected she might also end up on Western’s campus.

“It’s kind of a family thing … we grew up coming to Gunnison, [I heard] stories about Gunnison and the University. We came to basketball camp here. [Attending Western] was always something that lived in the back of my head,” Lindsey said.

Although she had always considered coming to Western, Lindsey hadn’t planned on majoring in both Mathematics and Computer Science.

“When I first went to Western, I didn’t know what path I wanted to do … [or] what path I wanted to take,” Lindsey said.

She started out as a geology major. When it came time to take math classes to fulfill the Biology program requirements, though, Lindsey realized that she really liked the mathematics courses—enough that she changed her major to mathematics.

Then, in between exploring new trails and experiencing the Gunnison valley’s culinary options, Lindsey took on a few Computer Science courses and found that she loved those classes, too.

After some gentle encouragement from her professors, Lindsey declared Computer Science as her second major. She credits her current success, in part, to encouragement and flexibility from her professors in the program.

“If I was in a class and we were focusing on software development, but I had an idea for a project, they would let me follow that—because they knew that was the career path I wanted to go down,” Lindsey said of her professors. “They kind of kept pushing, and I’m glad they did. Without that, I wouldn’t be where I am.”

Now, Lindsey works as a data scientist for Ruffalo Noel Levitz, a higher education consulting firm. In this role, Lindsey is able to flex both her computer science and mathematics muscles, creating predictive models and developing new products for various colleges and universities. She’s also the youngest sitting board member for the University of Iowa’s Tippie College of Business.

“Having math and computer science on any resume in today’s world is going to help you get into a good career … it’s going to give you good tools,” Lindsey said.

“In both majors I face problems every day, whether they’re design problems or literal math problems. It is fun, challenging, and rewarding to find solutions especially if it’s a problem I’ve been struggling with.” 

Erin Diller came to Western with a desire to explore the Art and Math majors offered. She found her passion in a Graphic Design emphasis after taking several art classes and meeting the professors.

Diller is from Weston, Colo.,—a small town that has a population of about 844 people.

“My town was pretty small. We had one school that was K-12, so I grew up knowing everyone in the town,” Diller said.  She was ready to head to college by the end of her senior year so she could meet new people and explore the Gunnison valley.

Diller has been studying Graphic Design and Math at Western for four years and is graduating in December 2017. She says her majors set her up well for life after college describes and that they remind her more of a profession than a major.

“I started as an Art major and I liked to draw but I realized that there’s no drawing major here. I decided on Graphic Design originally because it required me to study a lot of different things, then I fell in love with it. I have to have a variety of skills in order to be successful in my field,” Diller said.

Every day Diller confronts new challenges, and she confronts them all head on.

“In both majors I face problems every day, whether they’re design problems or literal math problems. It is fun, challenging, and rewarding to find solutions especially if it’s a problem I’ve been struggling with,” Diller said.

When these challenges emerge, Diller has help from her professors. With small classes, students at Western get a chance to get to know their professors and professors get to know the students. Professors learn the strengths of each student and know the best way to help each one.

“My professors would do anything to help aid me in my studies. They are super helpful and are always there when I need them. My advisor helps me the most with guiding my future and where my path is going to lead me,” Diller said.

When Diller graduates, she plans on pursuing a career in graphic design freelancing with a company and creating art on her own.

“I live in Quigley hall right now! I spend most of my time in the graphic design lab trying new and exciting things,” Diller said.

When Diller is not in Quigley, she is either filling her time with work-study in the studio or as a sports information student assistant or hanging out with her friends. She attends athletic events even when she is not working and enjoys hiking and exploring the valley.

“I wish that I would have started putting myself out there more as a freshman and gotten more involved. There is so much to do but I was quiet and shy,” Diller said.

Diller has enjoyed her time at Western, but she is ready to graduate and show the world what Western has taught her.

  • Bachelor of Science in Mathematics
    • Major
    • Minor
    • Secondary Licensure


    Mathematics students learn how to reason their way through unfamiliar territory, find familiar structures, make predictions and answer important questions. In a world saturated with big data, the ability to create meaning out of this information is increasingly relevant and desired in business, finance, engineering, medicine and the sciences. A major or minor in mathematics complements any degree that uses the scientific process.

    The Program

    • The Standard major gives a sound foundation from which one can pursue advanced degrees or enter the business world with excellent quantitative skills.
    • The Actuarial Science emphasis trains students to analyze risk for the insurance and finance industries.
    • The Secondary Licensure emphasis is for students who want to teach in high schools or middle schools, where a shortage of well-qualified math teachers provides excellent job opportunities.
    • The Data Analytics minor teaches students how to analyze large data sets and extract valuable knowledge from data. 

    Careers & Opportunities

    Job prospects are high for mathematics graduates. While many go on to earn advanced degrees, students can find positions right after graduation in the following areas: 

    • Actuarial science
    • Cryptography
    • Economics
    • Energy analysis
    • Financial planning
    • Fraud investigation
    • Investment analytics
    • Market research
    • Software testing
