It was being “bad” at math that resulted in my “loving” math! I grew up in a small farm town in Northern California. Pre-Algebra was not offered at my K-8 grade school, but I was still enrolled in Algebra 1 as a freshman. Lacking the proper prerequisite skills resulted in my struggles with that class. I wasn’t going to let math get the better of me, so I focused my efforts on conquering the subject. By the end of my freshman year, I had learned to love math!

Like many young people, when I graduated from high school I was confused about my place in the world. I wasn’t sure if college was for me, and took a few years off school in order to figure things out. It wasn’t until I took a few local community college math classes that I began to see the value of higher education and was able to form a plan for my future. From my local community college, I was able to transfer to UCLA and received a BS and MA in pure mathematics.

Math has always been my strongest and favorite subject. I began my collegiate studies at UCLA, where I earned a degree in Aerospace Engineering and gained a new appreciation for college academia through tutoring and my own studies. After undergrad, I decided to pursue my true passion and applied to graduate school at CSULB, where I successfully earned a degree in Applied Mathematics. There, I had my first experience with my own classroom and I have been hooked ever since!

Rachel Coleman
Assistant Professor, Math & Engineering

My interest in mathematics and problem solving led me to a bachelor’s degree in Mechanical Engineering from Stanford University. Following graduation, I worked for 15 years as a mechanical engineer in the aerospace and flow control industries. I followed my interest in mathematics and continued my education at CSU Fullerton obtaining a master’s degree in Mathematics where I also discovered my passion for teaching.

I always knew I wanted to teach mathematics to others. There is a feeling of accomplishment when a tough problem is not only solved but understood. I believe all my students are capable of being successful, even in a class, they may initially be nervous about. Participating in my classroom is about being supported and providing support to each other. We work together as a team as we strengthen our critical thinking skills and challenge ourselves with new material.

Kristin Hartford
Professor, Math & Engineering

I moved to California from Pennsylvania to accept a job at LBCC in 2000. Previously, I taught high school math and computer science in Stony Brook, New York, math and computer science at the International School of the Hague in the Netherlands, and undergraduate math courses at Penn State. ​​

Helping students reach their education goals, especially regarding completing statistics, is my passion.

I have always been a fan of solving math-related problems. I knew as soon as I have in contact with Physics in my freshman year at USC, this is my passion. I felt obsessed with seeking out unknown. One thing led me to major in Math and Physics. Later I decided to take more science classes such as Astronomy and Chemistry. My passion led me to seek out more education in Math and Physics in graduate schools. I did further studies at UCLA. There I fell in love with teaching. Many highly motivated students at USC and UCLA led to teaching at college level. It has been almost 20 years.

I am a tenured Professor with the Mathematics and Engineering Department at Long Beach City College since fall 1999. My degrees and experience in Mathematics and Engineering helped me to develop and implement the first online and hybrid courses in the Math department at Long Beach City College in the Fall of 1999. Consequently, I was approached by several colleges to collaborate and establish a web-enhanced course for them. This led to the start of the first online Math classes at East and West Los Angeles college as well.

My name is Jair, but most of my students call me Professor J. Since graduating from the University of California Santa Cruz, I knew I always wanted to teach math at the community college level. I take so much pride in being a full-time instructor for Long Beach City College (LBCC) because I was once a student here taking some of my general education courses. Also, it is pretty awesome to see the growth of LBCC, especially when I can say that the building my office is currently located in was once the parking lot that I would park in when I was a student.

I have known that I wanted to be a Math teacher since I was very young. I have a deep passion for Mathematics and for teaching and I love explaining the subject and answering questions, so ask away. I grew up in Romania and then moved to Germany where I earned my Master’s in Mathematics at the University of Tübingen. I came out to CSULB as an exchange student and ended up staying and earning another Master’s in Mathematics. I have been teaching at LBCC since 2000.

James Wan
Professor, Math & Engineering

I enjoy teaching math and have been doing that with dedication and love for nearly three decades. Graduated in 1990 from the University of California, Santa Barbara with Ph.D. in Statistics and Applied Probability, I came to teach at Long Beach City College and have taught most of the courses the Math Department offered. It gives me great pleasure knowing that I have made a difference in the lives of tens of thousands of students.

Conor Whelan
Assistant Professor, Math & Engineering

I always liked math. From a young age, I remember the satisfaction of finally solving an equation after hours of trying. After graduating with my Bachelor’s Degree in Math from Pitzer College, however, wanderlust got the best of me as I spent several years exploring various countries in Latin America and Asia. I am also an avid hiker having summited most of the highest peaks in California, several glaciers in the Andes, as well as having hiked the John Muir Trail.
