The advent of computers transformed science.  Large, complicated datasets that once took researchers years to manually analyze could suddenly be analyzed within a week using computer software.  Nowadays, scientists can use computers to produce several hypotheses as to how a particular phenomenon works, create computer models using the parameters of each hypothesis, input data, and see which hypothetical model produces an output that most closely mirrors reality. Computational biology refers to the use of computers to automate data analysis or model hypotheses in the field of biology.  With computational biology, researchers apply mathematics to biological phenomena, use computer programming and algorithms to artificially create or model the phenomena, and draw from statistics in order to interpret the findings.  In this course, you will learn the basic principles and procedures of computational biology.  You will also learn various ways in which you can apply computational biology to molecular and cell…

Today, the management of information systems is mostly associated with databases, the Internet, and server rooms.  However, “information management” has been around since before the invention of these tools.  It is as old as commerce itself, as traders, bankers, and merchants have always had reason to track sales and inventory.  Creditors must be aware of how much capital has been lent to borrowers and how much money has been deposited at banks.  Long before humans harnessed electricity, there was a need for information systems.  But currently almost all management of information systems is done electronically. Management Information Systems (MIS) is a formal discipline within business education that bridges the gap between computer science and the well-known business disciplines of finance, marketing, and management.  However, most students will only take one or two MIS courses in their undergraduate programs. You may not know it, but you use MIS every day.  If you use email, you are using MIS…
