Ted G. I think you could do web scraping like linkedin post scraper which is a chrome extension and it allows you to scrape posts from linkedin profiles.
Or else if u have a devoloper account you could also use some linkedin API .
Or if you want your linkedin data enriched you could also use enrichminion.com, i recently started using it and loving the quality and affordability.
sneha browser extension route would be pretty tedious, and I can't do this with LinkedIn API without a ton of approvals (that I probably wont get). I will explore enrichminion.com
