Mathematics & Science

Welcome to the Mathematics & Science Department! 

Science, Technology, Engineering and Math (STEM) based careers are pivotal in shaping today’s society. From the use of mathematics to project rocket trajectories, to drone technology assistance in areas devastated by natural disasters to cutting edge medical treatments that enhance patient outcomes, STEM based fields play a significant role in everyday life. 

The Redlands Community College Mathematics & Science Department offers the Pre-Professional Science degree (PPS) that will allow you to obtain a high-quality learning experience in a multitude of courses in life sciences, physical sciences, math and allied health sciences. In addition, we encourage students to reach outside of the classroom and participate in hands-on research through research based courses, service learning options, honors projects as well as internships.  Our grant funded programs in STEM based fields allow for a multitude of opportunities for our students. 

Redlands Community College Mathematics & Science Department offers courses that are used to satisfy the general education requirements for a multitude of degrees on campus. 

Whether a STEM major or taking our general education courses to fulfill a degree plan we strive to provide classes that will fit your schedule in a format that works for you, from a traditional classroom setting with daytime and evening classes to online courses. You will find a full spectrum of math and science courses. We also offer developmental math classes and have STEM tutoring centers on campus to help you get up to speed and ready for the next level. If you aren’t sure which math class you should take, visit with an advisor or take the Accuplacer assessment test

Our faculty strive to provide you with a learner-centered environment and one-on-one assistance to help you succeed in reaching your goals. 

Redlands Community College provides a learner-centered environment committed to academic excellence strengthened through service and civic engagement.

Scotti Charmasson, MNAS, Professor of Agricultural Science and Biology
Office: AGH-110 and ASC-119

Scotti Charmasson is originally from Northwest Missouri where she grew up on a cattle ranch.  She attended Northwest Missouri State University where she competed on the livestock judging team before transferring to Oklahoma State University to earn a Bachelor of Science in Animal Science. After graduating from OSU, she went on to earn a Master of Natural and Applied Science from Missouri State University in Springfield.  Her graduate research focused on the reproductive cycles of the highly endangered Grand Cayman Blue Iguanas. While in graduate school, she also had the privilege of traveling around the country to help artificially inseminate and ultrasound several different exotic species with the main focus being on elephants. Scotti joined Redlands in 2008 and currently teaches biology in the Science Department and several agriculture classes, such as animal science, animal reproduction, and artificial insemination in the Agriculture Department. Scotti feels it is a huge blessing to be able to work at an institution where she can share her passion for animal-related science with her students.


Brenda Allison Witt, M.S., Professor of Microbiology and Life Science
Office: ASC-109

Brenda Allison Witt earned her Bachelor of Science in Zoology and Master of Science in Biology from the University of Oklahoma where her research focused on better understanding the effects of toxic algae on zooplankton communities in lakes. She joined Redlands in 2015 and teaches several courses including microbiology, anatomy and zoology. She enjoys sharing her passion for science with her students, is always happy to mentor students on honors, service learning, and research projects, and strives to find ways to teach outside of the classroom. Her most recent venture is exploring the distribution of freshwater sponges in Oklahoma.

Gokul Kadel, Professor of Mathematics
Office: ASC-223
Dr. Gokul Kadel joined the Redlands Mathematics Department in 2018. He teaches variety of undergraduate mathematics and statistics courses offered by the department in the traditional face-to-face and online formats. Dr. Kadel earned his Ph.D. in Mathematics from Bowling Green State University, Ohio, Master of Science in Mathematics and Bachelor of Science in Mathematics, Statistics, and Physics from Tribhuvan University, Nepal. His primary research interests are in the area of Functional Analysis, and he has published his research articles in renowned peer-reviewed journals and has delivered research talks in regional and national level conferences. Before joining Redlands, Dr. Kadel held the position of Assistant Professor of Mathematics at Cameron University in Lawton where he taught courses ranging from developmental to upper division mathematics while being actively involved in the department’s undergraduate research program.

Peggy Clifton, Professor of Mathematics
Office: ASC-222
Peggy Clifton earned her Master of Education degree from Southwestern Oklahoma State University and completed the majority of her undergraduate course work at Tennessee Temple University in Chattanooga. She also holds a Bachelor of Science in Education from Oklahoma Baptist College with a minor in Mathematics. She joined Redlands in 1993 and has taught Statistics, Trigonometry, College Algebra, Basic Algebra, Intermediate Algebra and General College Math. She has also worked for various textbook publishers reviewing mathematics textbooks. Prior to teaching at Redlands, Peggy taught in private high schools in Tennessee and Oklahoma. Peggy’s mother dreamed of becoming a teacher and inspired her daughters to pursue teaching. Peggy’s three sisters, brother-in-law, and niece are all educators at the college or high school level. Peggy enjoys cross-stitch, her flower garden, church, traveling with her husband and spoiling her grandchildren.

Lisa Kastl, Professor of Mathematics
Office: ASC-221
