Douglas Gordon wrote a letter of recommendation for his former professor Vahid Azadeh Ranjbar. Gordon took Ranjbar's Aero-Thermal-Fluids Lab course, which combined theoretical concepts with numerical methods, empirical observations, and data analysis. Ranjbar was skilled at teaching the diverse subject areas required for the course, clearly communicating interconnected concepts. He was interested in conveying the complex subject matter to students in a straightforward way while stimulating their interest. Gordon's experience in Ranjbar's class was excellent and he would recommend Ranjbar without reservation as a professor.
