Julio Fernandez

This professor has earned a CULPA gold nugget

Dr. Fernandez is a very engaging, funny, and passionate professor! The course is essentially a Physiology course based on excitable cells (only). The course is divided into two parts (1) the physiology of neurology, and (2) physiology of muscle. There is are few physics concepts that will continue to reappear. As well as some calculus in graphing. Don't get bogged down on the physics and math- it is never tested in the exams. However, a general understanding of the concepts and followed by applications of the concepts is critical to get a good grade. Without a developed understanding of what the researchers were aiming, you won't be able to to score on the midterm. The average of the midterm was like a 29/45 - again its hard. However, the curve is very forgiving and Dr. Fernandez really takes care of your grade in the end. Had scored the average on both exams (midterm and final) and received an A overall. Though the exams are difficult, the most challenging are the discussions. These discussions are graded. So every thursday you will have to be prepared to discuss on a paper that should have won or has won a noble prize according to Dr. Fernandez. I'm speaking of the last paper Dr. Fernandez (lol). So they go over the paper and ask questions, the more you speak up and answer the questions the more checks you get. The # of checks get put on a bell curve and you get your grades based on that. The overall grade is 30% midterm, 30% discussion, 40% final. Exams were challenging because they would essentially be a thought-problem and predicting the result in a graphical manner. So the best prep would be to ask question!

I have mixed feelings about this class. Julio himself is a really swell guy- his passion for science shines through and you can tell he actually likes teaching, unlike the vast majority of Biology professors I have had at Columbia. The book is extremely helpful and one of the most clearly written ones I've encountered. It is a little lengthy but it has helpful information and graphs. The class itself is not really about disease as much as it is understanding the underlying mechanisms for how various parts of the body work (explaining the electrical events that lead to an action potential, etc.). That said, it was interesting enough and the papers were generally fairly interesting. Don't be intimidated by the equations and whatnot- you don't need a lot of math or even physics background to grasp the class material. Probably the best thing about the course is how available everyone is for help. The TA's hold office hours twice a week but are really open to meeting just about anytime and Julio constantly offers opportunity for extra help, and if needed, extra credit. Both the TA's, Dan & Ted, were really nice and helpful.

Julio was probably the best professor I had at Columbia. He is incredibly intelligent and excited about science. Moreover, he is a great teacher-- always excited to share his knowledge and be challenged. This class in particular highlighted his teaching style. Instead of learning principles from cartoons and diagrams in a textbook, we looked at the original papers from which the theories in textbooks are taught. In doing so, you not only learn great science, but also the process by which science is made. All in all, it was one of my favorite classes at Columbia and possibly my favorite science class that I have taken. I would recommend this class for anyone who has a genuine interest in the scientific method or research. The subject matter itself is daunting and difficult, but if you put in some effort you can get a lot out of the class.

He scared me at first because he randomly calls on people during discussion classes, but, he's actually quite easy going whether you know the answer or not. His discussion lectures can be boring, but a few were actually intriguing. He's very helpful in office hours, and a nice guy once you get past the initial intimidation. He's a much better teacher in office hours than in discussion, he can do a great job explaining things if you take the time to visit his office hours

He's great guy. Very intelligent, of course. Expects a lot of out of his students, but at the same time, itsn't very hard to please. He mainly just wants you to show thought and effort. He was one of the lectures for my semester (spring 2005). His lectures were somewhat dense and dry, but I love that him, and the other lecturers as well (especially Horst Stormer), are really passionate about what they teach. I imagine he'll be a very difficult professor, but I hope he'll be teaching one of the upper level science courses I take. P.S. He really likes people to come to his office hours.
