How do you interpret the feedbacks of my boss I have a PhD in biological sciences but working (for two years by now) as a data analyst (I can say something like a bioinformatician) in a university analysing cancer omics

My boss says that I am an excellent bioinformatician but I must learn how to structure my data when presenting or even before any analysis

He says I would not get any credit unless I learn this

Every morning we have online lab meeting, when seeing my colleagues presentation I feel too bad about myself

I see how they are deep and accurate in their statement

But me only see frigid feedbacks, even PhD students in our lab don't take me serious never ask me to help them in their data

I feel too isolated.. I am getting to the end of my career but everyday I feel the current position would be my last job opportunity in my life

How would you approach such an annoying situation in your academic life?

Thank you for any word
There are certain conventions on how to structure thoughts, write texts, present information, and give talks. Find out and learn them. A first step is to ask your supervisor for specific advise, so you can improve these skills.

For example, is is common to finish sentences with a period and to group sentences together to form paragraphs. Note that practically everybody does this. It is a convention to efficiently convey ideas by giving the reader some expected structure she can hold on to. If you don't do this, this already sticks out as part of a "bad presentation". So, learn what conventions exist and use them.

This may help to address presentation and writing part:
