Thank you so much, sir. Yes, I already completed 50+ courses on Coursera, but now I'm thinking of software or tools that are necessary for Biological research.
It all depends on what you want the tools to do for you. If you are working with statistics and want to build charts, for example, Adobe Illustrator is a solid program. I have an ecologist friend who uses it in his research. Of course, there are other programs that will do the same, like Microsoft Excel. As far as online learning platforms, you can probably take a good quick class on Udemy or Skillshare.
The understanding of Information Graphics, Scientific Illustration and Data Visualization will be very helpful when you begin to design and present biological information, images and data.
Try to gain an understanding of the basic ideas of the latter and plan to develop and refine your skills over time. The best way I know is to work with someone
(a professor) doing research and publishing in your area of interest.
For information graphics I highly recommend a book by Edward Tuft, "Envisioning Information". In addition take courses that help you develop skills in scientific illustration and gain an understanding of the the basics of image processing and graphic design.
Lastly, I recommend ImageJ (from the NIH in USA) software. Its open source image processing software. And is supported by a diverse group of people develop tools and plug-ins for specific areas of research. in addition, Adobe Creative Cloud software and MS Excel.
