Celal Ayder.

Celal Ayder

Celal Aydar has been teaching math for 17 years at the elementary, middle and high school levels. He loves teaching and working at Buffalo Academy of Science Charter School as a college guidance advisor. Among the positions he has held during his career as an educator — including director of counseling, AP coordinator, math department head and math teacher — he enjoys his current role as an advisor the most. Helping students to reach their goals gives meaning to his life.

Aydar earned a Bachelor of Science in mathematics education in 2000. After completing his master's in educational leadership this semester, he will be working toward his PhD in curriculum, instruction and the science of learning with an emphasis in mathematics education.

Anna Clifford

Anna Clifford.

Anna Clifford, a current graduate student earning her EdM in adolescent mathematics education at UB, recently graduated from SUNY Geneseo with a BA in mathematics and a NYS teaching certification in mathematics for grades seven to 12. Originally from a small town in northwestern New Jersey, she fell in love with New York after spending four years attending college here and decided to move to Buffalo to pursue her graduate education.

Clifford has gained valuable experience working closely with mathematics students. In Boston, she worked as a seventh grade TA at MathPOWER, an urban summer math academy. She taught eighth, ninth and tenth graders during her student teaching experience, covering math 8, algebra and geometry content. This past year, she worked at UB’s Gifted Math Program as a teaching assistant for the GMP I class. Clifford learns just as much, or more, from her students as they learn from her, and she is very excited to work with the bright young minds in Summer Math Program.

In her free time, Clifford enjoys hiking, traveling, cooking, yoga, reading, swing dancing and playing the French horn.
