My name is Ali Abghari, Ph.D., and I am a biological engineer with more than 4 years of industrial experience in the field of biotechnology in the USA. I have been honored to know Amir Heydari since I was doing my graduate study. At that time he was my academic adviser. Amir has an extensive background in the development of DOE for the optimization of processes. He obtained his Ph.D. from the best engineering school in Iran. He knows how to use different statistical tools and programs to come up with most effective and practical DOE for optimizing processes. His record is impressive. He has authored/co-authored more than 20 research articles. Apart from his impressive publications, he has taught several academic courses at the undergraduate and graduate levels in person and on-line. In my experience, Amir Heydari has a unique way of teaching. He does his best to make sure that the student has learned a new practical skill to advance his career. He is very on time and considerate. He loves mastering new skills and teaching them to those who work in industries and academy. His accomplishments so far have distinguished him amongst his peers and propelled him to the forefront of chemical and biochemical engineering research.

I highly recommend Amir. He is so knowledgeable and patient. His method of teaching is impressive.

Dr. Amir is very cooperative. He guided me to learn in effective ways and made productive use of time.

I settled for Amir after receiving lessons from 3 tutors because he is not only an authority in thermodynamics but passionately shares his knowledge. He is dependable, keeping to scheduled lessons and replies to messages promptly and politely. I have no previous knowledge of thermodynamics but now I am confident with the subject. Thanks, Amir.
