F27 never dated, never been in a relationship, never been confessed to, is there any chance for me anymore ? Or am I too old?

I have been noticing recently that less and less people would want a person my age. Guys are going for younger girls. Everyone in my family is already married( younger than me) and i never ever experienced a man seeing me in that way. In my workplace there are only 2 guys and both of them are already married. Meeting up with strangers Online is dangerous where i am from as there are many many thugs. A bit of background: i am currently doing my phds in engineering. My only requirement is said person to be of similar educational level ( or any job that requires a higher education like pharmacist / doctor/ lawyer/ anything that needs a higher degree really) as I lived with a family with parents having drastically different job levels and income and it caused some tension in the home with one parent being reliant on the other completely for money. Is the phd a turn off? I do put it on my profile on my socials, is that a turn off??
