About the Course

This course introduces you to the basic biology of modern genomics and the experimental tools that we use to measure it. We'll introduce the Central Dogma of Molecular Biology and cover how next-generation sequencing can be used to measure DNA, RNA, and epigenetic patterns. You'll also get an introduction to the key concepts in computing and data science that you'll need to understand how data from next-generation sequencing experiments are generated and analyzed. This is the first course in the Genomic Data Science Specialization....

It was well taught. I liked the fact the two professors focused on two different subjects- biology and statistics portion of this course. The paragraphs written below each video was extremely helpful.

Relatively nice introduction course, contents are maybe rather limited, yet as an instructive course, it does provide a clear overview which correlates well with the required answers for the quizzes!

This is from an AS Level student with relatively low knowledge about Genome and the technology regarding it, this course was perfect for beginners who wish to just learn. The basics were explained and at times acknowledged. But, after this course, I'm definitely determined to proceed in this specialization.

The instructors are proficient, well-spoken, and did an amazing job at explaining and the quizzes were definitely well-constructed. I loved learning about Genetics not just in terms of biology but through a computational and statistical perspective.

A good, very brief, overview of genomic data science covering basic molecular biology, techniques, CS and statistics. The quizzes are not difficult and the end project is quite interesting. Would appreciate explanations of the correct answers after getting our scores. You do need to have a bit of a background in high school / introductory college classes on these topics, especially for the biology part as the lectures go pretty fast. Overall a good overview.

I've learned many new things. Coming from the CS / Data Science background, this was a great introduction to biology side of genomics.

I'd also recommend to all students in this class an excellent book on the history of genetics and genomic research that was recommended in my Data Science course at Indiana University: "The Gene" by Sidhartha Muherjee. The book is non-technical, but gives a great background knowledge and motivation for further study.

This is a great course that covers a lot of ground very quickly, including an overview of the central dogma of biology, mitosis and meiosis, and basic concepts in computer science and statistics. The lessons are clear, understandable, move at a good pace, and are full of practical examples applying concepts to actual problems in genomic data science. This class was a great starting point for the specialization and I highly recommend it.

this was good course. Its really appreciating that you are teaching students sitting at home and learning online. this course was also good but i feel difficulty in learning 4th week course. Especially calculating p value and plotting data . I think that should be more precisely and should be describe with more examples. Thank you so much for this course and for increasing my knowledge.

This is my first online course I ever took. I did not know much about importance of online courses before this course but while taking this course I was only wishing that if only I had known these things before while I was doing my masters research, it would have been a great help. Still, I am glad that I am able to know these things now. Thanks to the creators of this course.

My name is Jose Antonio. I am looking for a new Data Scientist career (

I did this course to get new knowledge about Data Science and better understand the technology and your practical applications.

The course was excellent and the classes well taught by the Teachers.

Congratulations to Coursera team and Teachers.

I think this course was a good introduction to various aspects of genomic data science. The quizzes were great for testing the understanding of the material and the paper for the final exam was an interesting read. I liked the section on statistics, where a real life example was used to motivate the importance of statistics in genomic data science.

The content of the course is concordent with the course title. Videos and readings are spread into weeks classified within topics. Quizzes are qualified, some of them were challenging :) Special thanks to Dr. Salzberg and Dr. Leek. Happy to take to course and stepping into "Genomic Data Specialization". I am planning to take following courses.

This is the best way to keep up with the speed of innovation for a genomics veterans. I have been supporting bioinformatic solutions for 15 years and highly recommend this course. Even for the people involved in genomics for decades. Excellent instructors and content. Thank you JHMI!

There were a few minor points that I didn't agree with, but I posted those in the discussion forum.

Overall, I thought this was an excellent course. I am going to suggest that anyone who wants to perform a sequencing experiment be able to pass this course before they submit a sample!

As a clinical scientist, the course gives you a taste of the field in a way that you have not thought of before. The final project was a bit challenging and daunting!

Overall, the professors presented the material in a way that is easy to understand and follow up with.

This first course gives a high level overview of the material to come, and mentions many of the topics I hope to learn about like next-generation sequencing and DNA methylation patterns. I'm excited to move towards the next courses that involved diving into some code.

Strong intro. I have a good amount of Data Science experience, so intro lectures generally make me fall asleep. This is the first one I enjoyed. Felt like a good balance of a few key topics from general data science and genomics topics that were new to me.

I learned so much in this course. There are lots of basics in genomics that I "sort of" knew about but didn't really understand. Same for data science. This course helped me getting my footing in this exciting branch of contemporary biological inquiry.

Explains genomic technologies and important statistical tools needed to effectively start more in depth study. Highly recommend especially if you are already familiar with biology and/or computer science but want to specialize in genomics.

Totally love this course. Illustrated the basics of genomics, computational biology and statistics in a very simple and clear way. Helped elucidating many previously confounding concepts, eg, genomics vs genetics, permutaion test, etc...

The course had a relevant pace, gettnig more and more complex and difficult in later weeks. The overall explanations were easy-to-understand, well described and interesting enough that this was my only second course finished on Coursera!

Very interesting course. With a little investment of time, the course offer a good introduction, it is full of content and the final task is very interesting.

Very satisfied and lookin forward to the next course of the specialization.

It was a really good course for introduction with the genomics and all related to it. I like that the course can be attended without paying the fee, unlike some others in this Specialization. Keep up the good work!

Brilliantly put together with conversational language thus making it very easy to follow all the videos. The instructors are experts in the field thus were able to make the course very simple, yet with good depth!
