I have recently completed my masters and got a job in finance.  I deal with the study of investments.  Do you know much about finance?
I try to invest on my own, but I certainly haven't studied it to the same extent. I'm an engineer by trade.
Finance is an interesting subject.  You must know a bit about it to do your own investing. In my work we aim to price assets based on their risk level and their expected rate of return.
Would you have any advice for someone like me who is a bit leery of jumping into equities at the moment?
Well it is difficult to tell you too much it all depends on your circumstances and personal financial situation.  
I'm a bit heavily invested in real estate and am looking to diversify. It's just that I don't have any confidence in any investment vehicles being a good buy today.
Real estate is a prime investment.  if you are unsure, stick with what you are comfortable with at present.  Dealing with the assets and liabilites over time under conditions of different degrees of uncertainty and risk can be stressful.
I know the stress for sure. I've been a bit concerned lately about flat yield curves on treasuries. Have you noticed that?
Yes interestingly it is something that is a big topic at work.  I will need to do a bit moe research myself though to ensure I am uptodate. The yield curv shows several yeild or interest rates accross different lengths whether it be 2 months, 2 years or more.
It looks like to did in the 80's right before interest rates jumped to astronomical levels. Maybe the best game is to sit and wait?
