Statistics. I just finished my master's in biostatistics, but I didn't want to stop before PhD because, unlike most fields, a PhD is very desirable in industry outside of academia.
Very cool. I'll admit I'm not a fan of statistics but I appreciate the work and need for them. Good luck!
Thanks, and thanks for not giving me the usual response! Most people have a reaction somewhere between disgust and pity when I tell them my field. I absolutely love it though. It's creative, mentally taxing, and open-ended like pure mathematics as well as more immediately useful.
You're welcome. I did learn a lot when I studied it in undergrad for math requirements and I found that it was more useful than I thought. It's just not for me. I hope you get a glorious break before things start up again.
