I've been watching the Andrew Huberman Podcast lately.

There are many things to learn from his podcast on a wide range of topics like mental health, physical health, etc.

He invites many professors and highly educated folks to share their knowledge in their specific expertise.

"expertise" and "knowledge" are interchangeable in this sentence so it's better to just pick one.

He himself is a Stanford university professor himself.

I think it's just more natural to put "himself" at the end here.

Even though he has also many(much) valuable knowledge on different fields also, still he ishe is still very passionate about learning new things.

knowledge is uncountable, so you would use "much" instead of "many" for it. But it's also optional in this sentence to include it all, I think.

You used "also" twice in the first clause, better to just keep one.

The last podcast that I listened was all about the idea of learning how to learn thing.

Originally is grammatically correct, but "thing" is pretty casual for this topic.

TOn this podcast he invited a computational neuroscientist, hewho is also a professor and PHD in physics.

Listening to and observing their way of communication helps me to improve my overall eEnglish skill.

That professor suggested that in order to learn the somethings properly and have mastery on the material we should do theory based learning as well as practically applying thoseat things by doing it.

And by writing here and getting feedback from amazing kind people it helps me a ton .

Traditionally it's "listening to" a podcast, but I know some podcasts are filmed, so maybe "watching" is correct.
