So I mentioned some allusions to Mae's backstory that I thought I'd elaborate on a little! There's obviously some stuff I won't get into for story spoiler reasons, but I wanted to give some context!
Mae's husband is Takeshi Ishikawa, she took his name when they got married, her maiden name is Hishiro. They've known each other since birth with their families having known each other for generations. It was actually the Ishikawas who helped the Hishiros immigrate to America! They grew up on the same block in New York and got married right after Mae got her bachelor's. They have two kids Ren, born 2060, and Shaun, born in 2077.
Her twin sister's name is Lin, and her notable surviving family members up until the bomb's drop are her father, her grandmother, and her aunt although her aunt and her aren't super close. Mae cut ties from her family when she went to college due to disagreeing with their... business, and Takeshi felt somewhat similarly although his parents weren't as involved. Eventually they fully reconnected, but it took a decade of miscommunication.
Mae ends up working on the PAM Initiative (or Project Oracle) as one of the core scientists along with Dr. Indra Ramarijan and Dr. Malcolm Davidson.
