Atit academy bioinformatics practical course
- 1. Bioinformatics Practical Course 80 Practical Hours Course Description: This course presents major ideas and techniques for auxiliary bioinformatics and the advanced applications. Points included incorporate arrangement, structure and capacity databases of DNA and protein particles, propelled succession and structure arrangement strategies, techniques for protein collapsing and protein structure expectation (homologous demonstrating, threading and ab initio folding) basics of molecular dynamics and Monte Carlo simulation, principle and application of machine learning, and techniques of protein structure determination (X-ray crystallography, NMR and cryo-EM). Accentuation is on the comprehension of the ideas instructed and the pragmatic usage, with the target to help understudies to utilize the front line bioinformatics devices/strategies to tackle issues in their own exploration. Prerequisite: Good ability of computer coding (with at least one language, such as MATLAB) are highly recommended. Instructor: Dr. Qais Yousef. Ph.D. in Computer Engineering. Specialized in Bioinformatics and Enabling Systems. Have worked on numerus researches in this field. Schedule and location: Three months. The practical course will be held in ATIT Academy. Projects and Assignments: Each session will contain practical project. Moreover, there will be homework assignments, including code writing and literature reading. Textbook: No one reference will be considered for this course, however, related materials will be shared with students.
