One of the most incredible professors I've ever taken at Northeastern. Not only is Professor Engen an excellent lecturer but he's passionate and that passion transfers over to his students. His assignments are manageable but definitely take loads and loads of hard work - he does try to make the content relatable though which is fun. Greatest guyCHEM5620 2021-01-24 20:08:54 +0000 UTC
Professor Engen's Protein Chemistry course was absolutely amazing. He covers a huge amount of material. All the tests are take-home, but dont be fooled, they are all hard as hell (avg grade ~70. It also helps that he is an amazingly attractive and personable man. If you like nerdy and sexy scientists...you'll love him.CHMG322 2009-07-14 15:22:45 +0000 UTC
He is very compreshensive in his teaching methods. You really learn alot not just memorize for tests. I highly recommend taking a class with him.CHMG222 2008-02-26 12:47:30 +0000 UTC
OMG, when I took this class a few years ago, it was so hard and I was frustrated with all the work. But I'm so glad now because I really learned a ton and it's been very valuable in my job.CHEM5620 2018-01-21 18:28:11 +0000 UTC
The lecture material is interesting and he is a good teacher. Outside of class, this is a total nightmare. Do not take this course unless it is a requirement. He told us he wants wants us to spend 1-2 hours on his homework per day and boy did he mean it. So much busy work and you basically have to teach yourself to use the software. Nightmare.CHEM5620 2017-02-05 07:35:36 +0000 UTC
Protein Chem is hard! but Professor Engen really teaches. You cannot get out of this class without learning a lot. Don't get behind in the reading or you will be dead.CHEM5620 2011-03-30 20:44:45 +0000 UTC
Protein Chemistry was the best class I've taken at Northeastern and Prof Engen is one of the best professors. If you have a chance, take a class from him - but get ready to learn something and to work for it.CHEM5620 2010-04-20 16:21:51 +0000 UTC
