Spring Semester 2013  (Bioprocess Engineering, ChE453)

Green Hall L0159 Schedule: Tuesday and Thursday: 10~11:30am

Office Hours: 11:30–1:30 Tuesday and Thursday TA: Lian He (Computer Lab Instructor)

This course not only gives an overview of bioprocess engineering fundamentals, but also focuses on: 1. how systems biology and molecular biology have been applied to understand cellular metabolisms and to induce cellular production of useful compounds; 2. how modeling approaches can be used to analyze and optimize the bioprocesses; 3. Bioprocessing applications related to bioenergy. 



I highly recommend you to attend EECE 595C-BioMolecular Engineering lectures (taught by Fuzhong Zhang). You may just sit in the class without registration. . It will be very helpful for your PhD research, and it will also be helpful for your qualify exam. This class is on Tuesday and Thursdays (5:30PM-7:00PM; Lopata Hall  302 ).  The class's schedule is below.
